title: Active-Active Redis applications

title: Overview

text:
Active-Active databases store data across multiple regions and availability zones.  This improves scalability, performance, and availability, especially when compared to standalone databases.

To create Active-Active databases, you need a Redis Cloud Pro subscription that enables Active-Active Redis and defines the regions for each copy of your databases. See [Create an Active-Active database]() for instructions.

Active-Active databases are distributed across multiple regions (geo-distribution).  This improves performance by reducing latency for nearby users and improves availability by protecting against data loss in case of network or resource failure.

Active-Active databases allow read and write operations in each copy.  Each copy eventually reflects changes made in other copies ([eventual consistency]()).  Conflict-free replicated data types (CRDTs) synchronize read and write operations between copies.  CRDTs ensure consistency and resolve conflicts.

Active-Active databases use TLS to synchronize data between regions.  You can also use TLS to encrypt client connections.  See [Transport Layer Security (TLS)]() for more information.

When developing for Active-Active databases, you need to consider some important differences. See [Develop applications with Active-Active databases]() for related information.

Active-Active subscriptions on Redis Cloud are limited to a maximum of 10 regions and 10 databases.

title: Active-Active geo-distributed replication highlights

title: Multi-zone

text: Geo-distributed replication maintains copies of both primary and replica shards in multiple clusters. These clusters can be spread across multiple availability zones. Active-Active Redis uses zone awareness to spread your primary and replica shards across zones, which helps protect against data loss from regional outages.

title: Local latency with unique endpoints

text: Applications can connect to a specific copy of an Active-Active database using its unique endpoint. For local latency, configure your application to use a database endpoint in the closest region.

title: Conflict resolution

text: Active-Active databases use special data types called conflict-free replicated data types (CRDT). These automatically resolve conflicts that occur when writes are made to different clusters at the same time.

title: Failover handling

text:
After a failure at the process, node, or zone level, Active-Active databases automatically promote replica shards to replace failed primaries, copy data to new replica shards, and migrate shards to new nodes as needed. This reduces downtime and makes the most of your computing resources, even in the event of a failure.

However, Active-Active databases do not have a built-in [failover](https://en.wikipedia.org/wiki/Failover) or failback mechanism for application connections. To handle cluster-level failures, you should implement one of the following disaster recovery strategies to redirect traffic between regions:

- [Network-based](): Global traffic managers and load balancers for routing.

- [Proxy-based](): Software proxies handle detection and routing logic.

- [Client library-based](): Database client libraries with built-in failover logic.

- [Application-based](): Custom application-level monitoring and connectivity management.

For more information and guidance on which disaster recovery strategy to implement, see [Disaster recovery strategies for Active-Active databases]().

Data automatically syncs to a recovered cluster when it returns to a healthy state.

1. Select **Continue** to add the region to your Active-Active deployment.

Redis Cloud will provision the new region in the background and add it to all databases in the subscription. You aren't allowed to make changes to the database settings while this process is running.

Your database will still be available, but you may notice some increased latency. This process will take some time depending on the size of your database.

title: Edit regions

text:
To edit the local throughput settings for a database instance or remove a region from the deployment, select **Edit regions** in the **Regions** tab of the subscription page.

From here, you can:

- [Edit local throughput](#edit-local-throughput) for a database instance
- [Remove a region](#remove-region) from the subscription

After making the desired changes, [save and confirm the changes](#save-and-confirm-changes).

title: Edit local throughput

text:
To edit the local throughput settings for a database instance:

1. Select the region you want to edit.

1. Add or reduce the local read and write throughput for each database in that region in the **Local reads ops/sec** and **Local writes ops/sec** fields.

title: Remove region

text: To remove a region from an Active-Active deployment, select the **Delete** button for the region you want to remove.

title: Save and confirm changes

text:
After making your changes, select **Save changes** to apply them. You'll need to review and confirm the changes and any updated costs before they are applied. Select **Confirm** to apply the changes.

Redis Cloud will make the desired changes in the background. You aren't allowed to make changes to the database settings while this process is running.

Your databases will still be available, but you may notice some increased latency. This process will take some time depending on the size of your database.


title: Back up and export a database

title: Overview

text:
The backup options for Redis Cloud databases depend on your plan:

- Redis Cloud Pro subscriptions can back up or export a database on-demand and schedule daily backups that occur during a set hour.

- Paid Redis Cloud Essentials plans can back up or export a database on-demand and schedule backups that occur every 24 hours.

- Free plans cannot back up or export a database through the Redis Cloud console.

The number of database backups that can run simultaneously on a subscription is limited to 4 by default.

Backups are saved to predefined storage locations available to your subscription. Backup locations need to be available before you turn on database backups.  To learn more, see [Set up backup storage locations](#set-up-backup-storage-locations).

Backups are saved in RDB format. If the database is comprised of multiple shards, an RDB file will be created for each shard of the database. For more information on restoring data from a backup, see [Restore from an RDB file]().

Here, you'll learn how to store backups using different cloud providers.

title: Turn on backups

text:
To turn on database backups:

1. Sign in to the [Redis Cloud console](https://cloud.redis.io/).

1.  Select the database to open the **Database** page and then select **Edit**.

1.  In the **Durability** section of the **Configuration** tab, locate the **Remote backup** setting:

When you enable **Remote backup**, additional options appear.  The options vary according to your subscription.

|Setting name|Description|
|:-----------|:----------|
| **Interval** | Defines the frequency of automatic backups.  Paid Redis Cloud Essentials databases are backed up every 24 hours.  Redis Cloud Pro databases can be set to 24, 12, 6, 4, 2, or 1 hour backup intervals. |
| **Set backup time** | When checked, this lets you set the hour of the **Backup time**. (_Redis Cloud Pro only_) |
| **Backup time** | Defines the hour automatic backups are made.  Note that actual backup times will vary up in order to minimize customer access disruptions.  (_Redis Cloud Pro only_)<br/> Times are expressed in [Coordinated Universal Time](https://en.wikipedia.org/wiki/Coordinated_Universal_Time) (UTC).|
| **Storage type** | Defines the provider of the storage location, which can be: `AWS S3`, `Google Cloud Storage`, `Azure Blob Storage`, or `FTP` (FTPS). |
| **Backup destination** | Defines a URI representing the backup storage location. |

title: Back up and export data on demand

text:
After backups are turned on, you can back up your data at any time.  Use the **Backup now** button in the **Durability** section.

You can only use the **Backup now** button after you turn on backups.

title: Set up backup storage locations

text:
Database backups can be stored to a cloud provider service or saved to a URI using FTP/FTPS.

Your subscription needs the ability to view permissions and update objects in the storage location.  Specific details vary according to the provider.  To learn more, consult the provider's documentation.

Be aware that provider features change frequently.  For best results, use your provider's documentation for the latest info.

Select the tab for your storage location type.

**AWS S3:**

To store backups in an Amazon Web Services (AWS) Simple Storage Service (S3) [bucket](https://docs.aws.amazon.com/AmazonS3/latest/userguide/creating-buckets-s3.html):

1. In the [AWS Management Console](https://console.aws.amazon.com/), use the **Services** menu to locate and select **Storage** > **S3**.  This takes you to the Amazon S3 admin panel.

1.  Use the **Buckets** list to locate and select your bucket.  When the settings appear, select the **Permissions** tab, locate the **Bucket policy** section, and then click **Edit**.

    -  If there is no existing bucket policy, add the following JSON bucket policy. Replace `UNIQUE-BUCKET-NAME` with the name of your bucket.

        [code example]

    - If a bucket policy already exists, add the following JSON policy statement to the list of statements. Replace `UNIQUE-BUCKET-NAME` with the name of your bucket.

        [code example]

1. Save your changes.

1. If the bucket is encrypted using [SSE-KMS](https://docs.aws.amazon.com/AmazonS3/latest/userguide/UsingKMSEncryption.html), add the following statement to your [key policy](https://docs.aws.amazon.com/kms/latest/developerguide/key-policy-modifying.html). If you do not have a key policy, see [Creating a key policy](https://docs.aws.amazon.com/kms/latest/developerguide/key-policy-overview.html). Replace `UNIQUE-BUCKET-NAME` with the name of your bucket and `CUSTOM-KEY-ARN` with your key's [Amazon Resource Name (ARN)](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference-arns.html).

    [code example]

Once the bucket is available and the permissions are set, use the name of your bucket as the **Backup destination** for your database's Remote backup settings. For example, suppose your bucket is named *backups-bucket*.  In that case, set **Backup destination** to `s3://backups-bucket`.

To learn more, see [Using bucket policies](https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucket-policies.html) on the AWS docs.

An AWS S3 bucket can be used by only one Redis Cloud account. If you have more than one Redis Cloud account, repeat the setup steps for multiple buckets.

**Google Cloud Storage:**

To store backups in a Google Cloud Storage [bucket](https://cloud.google.com/storage/docs/creating-buckets):

1. Sign in to the Google Cloud console.

1. In the console menu, locate the _Storage_ section, then select **Cloud Storage > Buckets**.

1. Create or select a bucket.

1. Select the **Permissions** tab.

1. Select the **Grant Access** button and then add:

    [code example]

1. Set **Role** to **Storage Legacy Bucket Writer**.

1. Save your changes.

Use the bucket details **Configuration** tab to locate the **gsutil URI**.  This is the value you'll assign to your resource's backup path.

To learn more, see [Use IAM permissions](https://cloud.google.com/storage/docs/access-control/using-iam-permissions#bucket-iam).

**Azure Blob Storage:**

To store your backup in Microsoft Azure Blob Storage, sign in to the Azure portal and then:

1. [Create an Azure Storage account](https://docs.microsoft.com/en-us/azure/storage/common/storage-account-create) if you do not already have one.

1. [Create a container](https://docs.microsoft.com/en-us/azure/storage/blobs/storage-quickstart-blobs-portal#create-a-container) if you do not already have one.

1. Find your storage account's primary access key. See [Manage storage account access keys](https://docs.microsoft.com/en-us/azure/storage/common/storage-account-keys-manage) for instructions.

Set your resource's **Backup Path** to the path of your storage account.

The syntax for creating the backup varies according to your authorization mechanism.  For example:

[code example]

Where:

- *storage_account_access_key:* the primary access key to the
    storage account
- *storage_account_name:* the storage account name
- *container_name:* the name of the container, if needed.
- *path*: the backups path, if needed.

To learn more, see [Authorizing access to data in Azure Storage](https://docs.microsoft.com/en-us/azure/storage/common/storage-auth).

**FTP/FTPS Server:**

To store your backups on an FTP server, set its **Backup Path** using the following syntax:

[code example]

Where:

- *protocol*: the server's protocol, can be either `ftp` or `ftps`.
- *username*: your username, if needed.
- *password*: your password, if needed.
- *hostname*: the hostname or IP address of the server.
- *port*: the port number of the server, if needed.
- *path*: the backup path, if needed.

If your FTP username or password contains special characters such as `@`, `\`, or `:`, you must URL encode (also known as Percent encode) these special characters. If you don't, your database may become stuck.

The user account needs permission to write files to the server.

title: Advanced capabilities

summary: Describes Redis Cloud Advanced capability options.

title: Overview

text:
Advanced capabilities extend Redis database functionality by adding new features and data types.

Available options depend on your database plan and **Type**.

title: Redis Cloud Essentials {#essentials}

text:
All Redis Cloud Essentials databases with versions prior to Redis 8.0 support [Redis Stack](), which enables the most frequently used capabilities.

When the database **Type** is set to _Redis_, the Advanced capabilities section of the database details page displays the advanced capabilities included with the database and their versions.

Starting with Redis 8.0, all advanced capabilities provided by Redis Stack are included in Redis by default.

Redis Cloud is updated on a regular basis, which includes the advanced capabilities supported by the service. Versions displayed by the Redis Cloud console may vary from those shown above.  For the latest details of any capability, see [Redis Stack and Redis Software](). For more information about Redis Cloud version management, see [Redis version management]().

title: Redis Cloud Pro {#pro}

text:
By default, Redis Cloud Pro databases load all supported advanced capabilities. For versions prior to Redis 8.0, you can choose to load specific capabilities when you create your database. To choose which capabilities to load for your Pro database, [create it with custom settings]() and select **More options** when adding your database in the **Sizing tab** to view advanced capability settings.

You can select more than one advanced capability for a database, though there are limits:

- The following advanced capabilities can be combined in Pro databases:

    - Search and query
    - JSON
    - Time series
    - Probabilistic

- [Active-Active databases]() only support JSON and Search and query.

To remove a selected capability, clear its checkbox.

Starting with Redis 8.0, all advanced capabilities provided by Redis Stack are included in Redis by default.

To learn more, see [Redis Stack]() and [Redis Stack and Redis Software](). For more information about Redis Cloud version management, see [Redis version management]().

title: Search and query sizing

text:
When you create a Pro database with [Search and Query](), you must consider the sizing and throughput requirements for search and query when you define the dataset size and throughput for your database.

Use the [Search and query sizing calculator](https://redis.io/redisearch-sizing-calculator/) to estimate your index size and throughput requirements.

- **Dataset Size**: Add the estimated index size from the Sizing calculator to your expected dataset size.
- **Throughput**: Enter the total estimated throughput from the Sizing calculator when you enter your throughput.
- **Query performance factor**: The query performance factor adds extra power specifically for search and query. Select a factor to increase your queries per second by that amount.

#### Query performance factor

The query performance factor adds extra compute power specifically for search and query. When you create a Pro database with search and query, you can increase your search queries per second by the selected factor.

We recommend testing your application with a test database to see your baseline queries per second and determine how much you want to boost your query performance. After you have determined your queries per second and your desired performance factor, [create a new database]() with the desired performance factor and [migrate data]() from the test database to your new database.

For more info on how to use scalable search, see [Best practices for scalable Redis Search]().

The query performance factor is available for Redis Cloud Pro databases on Redis 7.2 and later.


title: Clustering Redis Databases

summary: Redis Cloud uses clustering to manage very large databases (25 GB and larger). Here, you'll learn how to manage clustering and how to use hashing policies to control how data is managed.

title: Overview

text:
For very large databases, Redis Cloud distributes database data to different cloud instances.  For example:

- When data grows beyond the RAM resources of a single server.

    Multiple shards should be used when data grows to 25 GB (50 GB for Auto Tiering) to create multiple shards.

- The operations performed against the database are CPU intensive enough to degrade performance.

    Clustering distributes operational load, whether to instances on the same server or across multiple servers.

This distribution is called _clustering_ because it manages the way data is distributed throughout the cluster of nodes that support the database.

title: How data is distributed

text:
A Redis Cloud cluster is a set of managed Redis processes and cloud instances,
with each process managing a subset of the database keyspace.
Clustering uses multiple cores and resources of multiple instances to overcome scaling challenges.

In a Redis Cloud cluster, the keyspace is partitioned into hash
slots. At any given time a hash slot resides on and is managed by a single
Redis server.

An instance that belongs to a cluster can manage multiple hash
slots. This division of the key space, known as _sharding_, is achieved by
hashing the key names, or parts of these (key hash tags), in order to
obtain the hash slot in which a key should reside. Redis Cloud supports several [hashing policies](#manage-the-hashing-policy).

Even when using multiple Redis processes, the use of a Redis
Enterprise Cloud cluster is nearly transparent to the application that
uses it. The cluster is accessible via a single endpoint that
automatically routes all operations to the relevant shards, without the
complexity of a cluster-aware Redis client. This allows applications to
benefit from using the cluster without performing any code changes, even
if they were not designed to use it beforehand.

When creating or editing a Redis database on Redis Cloud, the
system automatically calculates the number of shards needed based on
the database memory limit and required throughput.

title: Multi-key operations {#multikey-operations}

text:
Operations on multiple keys in a sharded Redis Cloud cluster
are supported, with the following limitations:

1. **Multi-key commands:** Redis offers several commands that accept
    multiple keys as arguments. In a sharded setup, you can run multi-key commands
    only if all the affected keys reside in the same slot (thus on the same shard).
    This restriction applies to all mulit-key commands, including BITOP, BLPOP, BRPOP, BRPOPLPUSH, MSETNX,
    RPOPLPUSH, SDIFF, SDIFFSTORE, SINTER, SINTERSTORE, SMOVE, SORT,
    SUNION, XREAD, XREADGROUP, ZINTER, ZINTERSTORE, ZUNION, ZUNIONSTORE, ZDIFF, ZDIFFSTORE
1. **Geo commands:** In GEORADIUS/GEORADIUSBYMEMBER/GEOSEARCHSTORE commands, the
    STORE and STOREDIST options can only be used when all affected keys
    reside in the same slot.
1. **Transactions:** All operations within a WATCH/MULTI/EXEC block
    should be performed on keys that are in the same slot.
1. **Lua scripts:** All keys that are used by the script must reside in
    the same slot and need to be provided as arguments to the
    EVAL/EVALSHA commands (as per the Redis specification).
1. **Renaming/Copy keys:** The use of the RENAME/RENAMENX/COPY commands is
    allowed only when both the key's original name and its new name are
    mapped to the same hash slot.
1. **Variadic commands**: The use of (MGET, MSET, HMGET, HMSET, etc..)
    and pipelining are supported with Redis Cloud cluster
    like if it were a non-cluster DB.

title: Hashing policies and hash tags {#manage-the-hashing-policy}

text:
The hashing policy determines how data is distributed across multiple Redis processes of a database. It uses a hashing function to map keys to hash slots in these processes, ensuring an even distribution of data for optimal performance and scalability.

The hashing function uses the entire key name to calculate the hash slot, unless the key name contains a **hash tag**, represented by a `{...}` pattern.

If the key contains a `{...}` pattern, only the substring between `{` and `}` is hashed in order to obtain the hash slot.

You can use the `{...}` pattern to direct related keys to the same hash slot, so that multi-key operations are supported on them. On the other hand, not using a hashtag in the key's name results in a (statistically) even distribution of keys across the keyspace's shards, which improves resource utilization. If your application does not perform multi-key operations, you don't need to construct key names with hashtags.

Redis Cloud offers 3 hashing policies, which differ in how hash tags are processed. These hashing policies are not always available.

Redis Cloud defaults to the [Redis hashing policy](#redis-hashing-policy) **when creating a new database**. You can select a different hashing policy during database creation, but you cannot change the hashing policy to or from the Redis hashing policy after the database is created.

title: Redis hashing policy

text:
The Redis hashing policy is identical to the [hashing policy used by Redis Open Source](). This policy is recommended for most users and you should select it if any of the following conditions apply:
- This is your first Redis Cloud account, and you are starting fresh.
- You are migrating data from Redis Open Source or other Redis-managed platforms.
- Your application does not use hashtags in database key names.
- Your application uses binary data as key names.

The Redis hashing policy allows for faster scaling where available.

title: Standard hashing policy

text:
The Standard hashing policy is mostly consistent with the Redis hashing policy, and will generate the same hash-slot calculation in the following cases:
1. Keys with a single hashtag: a key's hashtag is any substring between '{' and '}' in the key's name. That means that when a key's name includes the pattern '{...}', the hashtag is used as input for the hashing function. For example, the following key names have the same hashtag and are mapped to the same slot: foo{bar}, {bar}baz & foo{bar}baz.
1. Keys without a hashtag: when a key doesn't contain the '{...}' pattern, the entire key's name is used for hashing

In some cases, the Standard hashing policy behaves differently from the Redis hashing policy:
1. Using empty hashtags ("{}"): the Standard hashing policy does not ignore empty hashtags, so two keys that start with empty hashtags will be hashed to the same hashslot (while the Redis hashing policy would ignore them).
    For example: given 2 keys {}foo and {}bar, hashing would be:
    - Standard hashing policy: to the same hash slot
    - Redis hashing policy: to different hash slots
2. Using multiple curly brackets: when a key’s name contains multiple curly brackets, the Standard hashing calculation might be different than the Redis hashing policy.
    For example: given 2 keys {foo}bar} and {foo}qux}:
    - Standard hashing policy: substrings "foo}bar" and "foo}qux" will be used for the 1st and 2nd key respectively, hashed each key to a different hash-slot.
    - Redis hashing policy: the substring "foo" will be used for both keys, hashing them to the same slot.

To allow seamless transition between hashing policies, the following techniques are not recommended:
- Using empty hashtags to hash different keys to the same hashslot
- Using multiple curly brackets within a key’s name

title: Custom hashing policy

text:
The custom hashing policy is not available for accounts created after March 31, 2025.

For all other accounts, this policy is not recommended and will be deprecated in the future. Select this option only if you are already using a custom hashing policy with your existing Redis Cloud databases.

A Redis Cloud  cluster can be configured to use a custom hashing
policy. A custom hashing policy is required when different keys need to
be kept together on the same shard to allow multi-key operations. Redis
Cloud's custom hashing policy is provided via a set of Perl
Compatible Regular Expressions (PCRE) rules that describe the dataset's
key name patterns.

To configure a custom hashing policy, enter regular expression (RegEx)
rules that identify the substring in the key's name - hashtag - on
which hashing will be done. The hashing tag is denoted in the RegEx by
the use of the \`tag\` named subpattern. Different keys that have the
same hashtag will be stored and managed in the same slot.

Once you enable the custom hashing policy, the Redis Cloud's
default RegEx rules that implement the standard hashing policy are:

| RegEx Rule | Description |
|-----------|-----------------|
| .\*{(?\<tag\>.\*)}.\* | Hashing is done on the substring between the curly braces. |
| (?\<tag\>.\*) | The entire key's name is used for hashing. |

You can modify existing rules, add new ones, delete rules, or change
their order to suit your application's requirements.

If the Custom hashing policy is available, you can change the hashing policy between Standard and Custom after you create your database. However, hashing policy changes delete existing data
(using [`FLUSHDB`]()) before they're applied.

These changes include:

1. Changing the hashing policy, either from standard to custom or vice versa.
1. Changing the order of custom hashing policy rules.
1. Adding rules before existing ones in the custom hashing policy.
1. Deleting rules from the custom hashing policy.
1. Disabling clustering for the database.

title: Custom hashing policy notes and limitations

text:
1. You can define up to 32 RegEx rules, each up to 256 characters.
1. RegEx rules are evaluated by their order.
1. The first rule matched is used; strive to place common key name
    patterns at the beginning of the rule list.
1. Key names that do not match any of the RegEx rules trigger an
    error.
1. The '.\*(?\<tag\>)' RegEx rule forces keys into a single slot as the
    hash key is always empty. When used, this should be the last
    catch-all rule.
1. The following flag is enabled in our regular expression parser:
   - **PCRE_ANCHORED:** the pattern is constrained to match only at
        the start of the string which is being searched.

title: OSS Cluster API {#oss-cluster-api}

text:
The OSS Cluster API is only supported on Redis Cloud Pro databases. You can enable it in the **Performance** section of the configuration screen.

After you select OSS Cluster API, you can select **Use external endpoint** if you want to use the external endpoint for the database. Selecting **Use external endpoint** will block the private endpoint for this database.

The OSS Cluster API is supported only when a database uses the [standard hashing policy](#standard-hashing-policy).

Review [OSS Cluster API architecture]() to determine if you should enable this feature for your database.


title: Data eviction

summary: Data eviction policies control what happens when new data exceeds the memory limits of a database. Here, you'll learn the available policies and how to change which one is used for a database.

title: Overview

text:
The data eviction policy of a database controls what happens when new data exceeds the memory size of a database.  Typically, such situations require _evicting_ (or deleting) data previously added to the database.

You can [edit database details]() to change the **Data eviction policy** setting at the database level.

title: Available policies

text:
For each database, you can choose from these data eviction policies:

| **Available policies** | **Description** |
|:------------|:-----------------|
| allkeys-lru | Keeps most recently used keys; removes least recently used (LRU) keys |
| allkeys-lfu | Keeps frequently used keys; removes least frequently used (LFU) keys |
| allkeys-random | Randomly removes keys |
| volatile-lru | Removes least recently used keys with `expire` field set to true (*Default*) |
| volatile-lfu | Removes least frequently used keys with `expire` field set to true |
| volatile-random | Randomly removes keys with `expire` field set to true |
| volatile-ttl | Removes keys with expire field set to true and the shortest remaining time-to-live (TTL) value |
| no eviction | New values aren't saved when memory limit is reached

When a database uses replication, this applies to the primary database |

title: Prevent data eviction

text:
To avoid data eviction, make sure your database is large enough to hold required values.

Redis Cloud supports [Auto Tiering]() on Redis Cloud Pro and [Redis Flex]() on Redis Cloud Essentials
to prevent data eviction but maintain high performance.

Auto Tiering and Redis Flex can extend your database across RAM and Flash Memory and intelligently manage "hot" (active) data in RAM and "cold" (less active) data in Flash memory (SSD).

title: Active-Passive replication considerations

text:
When using [Active-Passive replication](), eviction and expiration only operate on the source (active) database. The target database does not evict or expire data while Active-Passive is enabled.

Do not write to the target database while Active-Passive is enabled. Doing so can cause the following issues:

- The target database cannot rely on eviction or expiration to manage local writes, requiring sufficient memory to handle both replicated data and local writes.
- Local writes create differences between the source and target databases, causing replicated commands to behave differently on each database.
- Inconsistent data can cause replicated commands to fail with errors, which will cause the synchronization process to exit and break replication.

title: Active-Active replication considerations

text: The eviction policy mechanism for [Active-Active databases]() kicks in earlier than for standalone databases because it requires propagation to all regions. The eviction policy starts to evict keys when one of the Active-Active instances reaches 80% of its memory limit. If memory usage continues to rise while the keys are being evicted, the rate of eviction will increase to prevent reaching the Out-of-Memory state.


title: Data persistence

summary: Data persistence enables recovery in the event of memory loss or other catastrophic failure. Here, you learn data persistence options, when they're available, and how to apply specific settings to individual databases.

title: Overview

text: Redis Cloud can persist data to enable recovery in the event of memory loss or other catastrophic failure.  When you enable data persistence, in-memory data is copied to persistent storage attached to the underlying cloud instance.

title: Persistence options

text:
Data can be persisted in one of two ways:

- An _Append-Only File_ (AOF) maintains a record (sometimes called a _redo log_ or _journal_) of write operations.  This allows the data to be restored by using the record to reconstruct the database up to the point of failure.

    The AOF file records write operations made to the database; it can be updated every second or on every write (_Redis Cloud Pro plans only_).

- Snapshots are copies of the in-memory database, taken at periodic intervals (one, six, or twelve hours). You can restore data to the snapshot's point in time.

AOF files provide greater protection (durability) than snapshots at the cost of resources and recovery time.
Although snapshot recovery is faster, the risk of data loss is higher, depending on the time between failure and the most recent snapshot.

If you turn off data persistence, data is lost when the database goes down.

title: Configure data persistence

role: configuration

text:
In Redis Cloud, data persistence is a database configuration setting that can be changed by [editing your database]() settings.

The availability of the setting depends on your plan:

- Free Redis Cloud Essentials plans do not support data persistence; the setting is disabled entirely.

- Paid Redis Cloud Essentials plans support AOF every second and all snapshot options.

- Redis Cloud Pro enables data persistence settings for every database.

When enabled, you can change the **Data persistence** setting to one of the following values:

| **Options** | **Description** |
|------------|-----------------|
|  None | Data is not persisted to disk at all. |
|  Append Only File (AoF) every write | _(Redis Cloud Pro only)_ Every write is recorded (synchronized to disk using `fsync`) |
|  Append Only File (AoF) every 1 second | Record is updated every second (synchronized to disk using `fsync`)|
|  Snapshot every 1 hour | A snapshot of the database is created every hour |
|  Snapshot every 6 hours | A snapshot of the database is created every 6 hours |
|  Snapshot every 12 hours | A snapshot of the database is created every 12 hours |

When you save changes to data persistence settings, the updates are applied in the background.  This means there is a brief delay while the new settings are applied.

When replication is enabled for a database, persistence is performed against replicas (copies) to reduce performance impact on the primary (_master_) database.


title: High availability and replication

summary: Describes database replication and high availability as it affects Redis Cloud.

title: Overview

text:
Database replication helps ensure high availability.

When replication is enabled, your dataset is duplicated to create a replica that is synchronized with the primary dataset.

Replication allows for automatic failover and greater fault tolerance.  It can prevent data loss in the event of a hardware or zone failure.

title: Options and plan support

role: parameters

text:
Redis Cloud supports three levels of replication:

- _No replication_ means that you will have a single copy of your database.

- _Single-zone replication_ means that your database will have a primary and a replica located in the same cloud zone. If anything happens to the primary, the replica takes over and becomes the new primary.

- _Multi-zone replication_ means that the primary and its replicas are stored in different zones. This means that your database can remain online even if an entire zone becomes unavailable.

Your replication options depend on your [subscription plan]():

- Free Redis Cloud Essentials plans do not support replication.
- Paid Redis Cloud Essentials plans and Redis Cloud Pro plans let you choose between multi-zone or single-zone replication when creating a subscription. You can also turn off replication.

Whether or not you can change your replication settings after database creation depends on your plan type and what type of replication you originally selected.

- For Redis Cloud Essentials, you select the kind of replication when you create your database. If you selected Multi-zone replication when you created your database, you can't change it to Single-zone or turn it off after database creation. However, if you selected No Replication or Single-zone replication, you can switch between the two at any time by [editing your Essentials subscription]().
- For Redis Cloud Pro, you select whether you want a multi-zone deployment during subscription creation. You can't change this setting or any [Zone settings]() after subscription creation. However, you can activate or deactivate replication for each database within the subscription at any time by [editing your database]().

title: Performance impact

role: performance

text: Replication can affect performance as traffic increases to synchronize all copies.

title: Dataset size

text:
For both Redis Cloud Essentials and Redis Cloud Pro, replication requires a memory limit that is double the dataset size of your database.

For Redis Cloud Essentials, the size of the plan you choose includes replication. Therefore, if you choose replication, the dataset size you can use is half of the stated plan size. For example, if you choose a 1 GB plan, Redis allocates 512 MB for the dataset size, and the other 512 MB for replication.

For Redis Cloud Pro, you select your dataset size when you create your database, and we calculate your memory limit based on the replication settings you choose.

title: Zone setting maintenance

text:
Zone settings can only be defined when a subscription is created.  You cannot change these settings once the subscription becomes active.

This means you can't convert a multi-zone subscription to a single zone (or vice-versa).

To use different zone settings, create a new subscription with the preferred settings and then [migrate data]() from the original subscription.

title: Availability zones

text:
You can reduce network transfer costs and network latency by ensuring your Redis Cloud Pro cluster and your application are located in the same availability zone.

To specify the availability zone(s) for your cluster, [create your Pro database with custom settings](), and select *Manual Selection* under **Allowed Availability Zones** in **Advanced options**.

For Google Cloud clusters and [Redis Cloud BYOC](), select an availability zone from the **Zone name** list.

For all other AWS clusters, select an availability zone ID from the **Zone IDs** list. For more information on how to find an availability zone ID, see the [AWS docs](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html#concepts-availability-zones).

If **Multi-AZ** is enabled, you must select three availability zones from the list.

For more information on availability zones, see the [Google Cloud docs](https://cloud.google.com/compute/docs/regions-zones/#available) or the [AWS docs](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html#concepts-availability-zones).

title: Size a Redis Cloud database

title: Content

text: Here, you'll find background info and conceptual details to help you customize your Redis Cloud databases to meet your needs.


title: Size a Redis Cloud database

title: Dataset size {#dataset-size}

text:
The dataset size of a database is a part of the full memory limit for the database. The memory limit represents the maximum amount of memory for the database, which includes data values, keys, module data, and overhead for specific features.  High availability features, such as replication and Active-Active,  increase memory consumption, so your dataset size and memory limit will be different.

For Redis Cloud Essentials, the plan size refers to the full memory limit, not the dataset size. Both the total memory limit and dataset size are listed under **Database details** when you create an Essentials database.

For Redis Cloud Pro, you define your dataset size when you create the database, and we calculate your total memory limit based on the features you choose.

Here are some general guidelines:

- Memory limit represents an upper limit.  You cannot store more data than the memory limit.  Depending on your other selections, available memory for data may be less than expected.

- [Replication]() doubles memory consumption; that is, 512 MB of data requires at least 1 GB of memory limit when replication is enabled. This affects both Redis Cloud Pro and Redis Cloud Essentials. For example, if you subscribe to a 1 GB Essentials plan, Redis will allocate 512 MB for your dataset and the other 512 MB for replication.

- [Active-Active]() also doubles memory consumption and the effect is cumulative with the impact of replication. Since Active-Active requires replication to be turned on, the memory limit impact can be as large as four times (4x) the original data size.

- [Advanced capabilities]() also consume memory. For search databases, consider index size when you size your database. See [Search and query sizing]() for more info.

Memory limits in Redis Cloud are subject to the same considerations as Redis Software; to learn more, see [Database memory limits]().

title: Throughput

text:
Throughput is the number of operations a database can handle over a certain period of time. For Redis Cloud databases, throughput is defined in operations per second (ops/sec).

For a Redis Cloud Pro subscription, you define throughput for a database when you create it. For a Redis Cloud Essentials subscription, your maximum throughput depends on your plan.

We use this setting to guide the allocation of compute power and network bandwidth, ensuring your database can handle the expected workload. However, the throughput specified is not guaranteed - actual throughput may be higher or lower depending on your workload and database configuration.

title: Throughput factors and variability

text:
Some factors that can affect throughput include:
- **Request size**: Smaller requests (under 3KB) consume less network bandwidth and may result in more operations per second than requested, while larger requests may result in fewer operations per second.
- **Command complexity**: Simple commands, like `GET` and `SET`, are faster and require fewer resources, whereas more complex commands involve more processing time and can reduce throughput. See the [Command list]() to see which commands are more complex than others.
- **Replication**: Using [multi-zone replication]() affects throughput as each write operation is executed asynchronously in each zone.
- **Security**: Some security options, such as [transport layer security](), may affect throughput.
- **Number of client connections**: The number of client connections affects throughput. Increasing or decreasing the number of client connections can result in higher or lower throughput.

title: Optimize throughput

text:
Here are some things to keep in mind for optimizing throughput:
- Optimize capacity planning and sizing of your Redis Cloud databases to meet your app performance requirements.
- Benchmark your app to understand what latency expectations are required, and adjust throughput accordingly.
- Test and monitor your app's performance and adjust the set ops/sec based on how if performs in real-world conditions.
- If your average request size is larger than 3KB, consider setting your throughput higher than expected.
- Track the slow logs using the [`SLOWLOG` command]() or the **Slowlog** tab on the [database screen]().
- Use [pipelining]() and [concurrent connections]() effectively to optimize throughput and latency.
- Search databases have their own throughput requirements. See [Search and query sizing]() for more info.

title: Frequently asked questions

text:
**Can my workload exceed the configured throughput?**

Yes, many workloads perform better than expected, especially with optimized configurations and ideal conditions.

**Why is my application getting less throughput than what I set?**

Factors like high connection counts, complex commands, large payloads, and network limitations can affect throughput. Test and adjust based on your application’s needs.

**How do I know the optimal throughput for my application?**

Start with the expected ops/sec. Most of the time, it’s more than enough. For an average request size of less than 3KB, we suggest specifying lower ops/sec than expected to reduce costs. For request sizes higher than 3 KB, we suggest specifying higher ops/sec than your target. Benchmarking your application under production-like conditions will help you find the best configuration.

**How does network bandwidth impact throughput?**

Insufficient bandwidth can bottleneck performance, especially with large request sizes.

**What is the expected latency for my application?**

Latency expectations vary by use case. Some applications tolerate milliseconds, while others require sub-millisecond performance. Benchmark your application to understand its latency profile.

title: Create a Redis Flex database

summary: Shows how to create an Redis Flex database on Redis Cloud and describes the best use cases for Redis Flex.

title: Overview

text:
Redis Flex databases have a tiered solid state drive (SSD) and RAM architecture. Using SSDs instead of RAM significantly reduces infrastructure costs, which means developers can build applications that require large datasets using the same Redis API.

Redis Flex databases are compatible with most existing Redis applications, except for applications that use Search and Query and Time Series.

Redis Flex is available on both Redis Cloud Essentials and Redis Cloud Pro.

title: Redis Flex use cases

text:
The benefits associated with Redis Flex are dependent on the use case.

Redis Flex is ideal when your:

- working set is significantly smaller than your dataset (high RAM hit rate)
- average key size is smaller than average value size
- most recent data is the most frequently used (high RAM hit rate)

Redis Flex is not recommended for:

- Broad access patterns (any value could be pulled into RAM)
- Large working sets (working set is stored in RAM)
- Frequently moved data (moving to and from RAM too often can impact performance)

Redis Flex is not intended to be used for persistent storage.

title: Where is my data?

text:
When using Redis Flex, RAM storage holds:
- Key indexes
- Dictionaries
- Hot data (working set), including frequently accessed keys and values

All data is accessed through RAM. If a key or value in flash memory is accessed, it becomes part of the working set and is moved to RAM. This data is referred to as "hot data".

Inactive or infrequently accessed data is referred to as "warm data" and stored in flash memory. When more space is needed in RAM, warm keys and values are moved from RAM to flash storage.

    - Select **Delete my subscription and stop my payment** to delete both the database and the subscription.

    - Clear **Delete my subscription and stop my payment** to delete the database but keep the subscription.

You will continue to be charged for your subscription until you delete it, even if there are no databases in your subscription.

1. Select **Delete database** to confirm your choice.

When the operation completes, the database and its data are deleted.


title: Import data into a database

title: Overview

text:
You can import an existing dataset into your Redis Cloud instance from an existing Redis server or an RDB file.

Data imported into an existing database overwrites existing data.
- If you import a dataset into the target database of an [Active-Passive setup](), the dataset will be overwritten by any changes to the source database.
- If you import a dataset into one region in an [Active-Active database](), the dataset will also be replicated across regions.

<br/>

Expired keys are not imported.
As a result, the number of keys in the source and destination databases can be different after the import is complete.

title: Prerequisites
