This guide shows how to create a Pro database in an existing subscription.
- If you don't yet have a Pro subscription, see Create a Pro database with a new subscription.
- If you'd rather create an Essentials database, see Create an Essentials database.
To create a database in an already existing Pro subscription:
-
Sign in to the Redis Cloud console.
-
Select the New database button.
This displays the Create database screen.
-
Select the type of subscription you need. For this guide, select Existing subscription, and then select your existing Pro subscription from the list.
After you select your existing subscription from the list, select Continue to go to the New database page.
You can also select your subscription from the subscription list and select Create database in this subscription.

The New database page is divided into sections, each dedicated to a specific category of settings. The following sections provide more details.
When you've configured your new database, click the Activate database button to create and activate it.

General section
The General section defines basic properties about your database.

The available settings vary according to your subscription plan:
Setting name | Description |
---|---|
Subscription | Read-only description of your Pro subscription, including cloud provider and region |
Active-Active Redis | Checked when the subscription supports Active-Active databases |
Auto Tiering | Checked when the subscription supports Auto Tiering |
Database name | A name for your database (required) |
Database port | Automatically or manually assigns a database port (range: 10000-19999). You cannot assign a port that is reserved or already in use. |
Type | Controls advanced database capabilities and protocol. Supported values include Redis and Memcached |
Advanced capabilities | Advanced data types used by the database. Choose from Search and query, JSON, Time series, or Probabilistic. Databases with Search and query have specific sizing requirements, see Search and query sizing for more information. |
Query performance factor | (Search and query databases on Redis 7.2 or later only) Adds additional compute power to process your query and vector search workloads and boost your queries per second. See Search and query sizing for more information. |
Supported Protocol(s) | Choose between RESP2 and RESP3 (Redis 7.2 only). See Redis serialization protocol for details |
Performance section
The Performance section lets you manage the maximum size, throughput, and hashing policy for a database.

Setting name | Description |
---|---|
Dataset size | Maximum size (in GB) for your dataset. See Dataset size for sizing considerations. Databases with Search and query have specific size requirements, see Search and query sizing for more information. |
Throughput | Defines throughput in terms of maximum operations per second for the database. See Throughput for more info. Databases with Search and query have specific throughput requirements, see Search and query sizing for more information. |
High availability | Replicates your data across multiple nodes, as allowed by your subscription plan. See High availability for more info |
Hashing policy | Defines the hashing policy. |
OSS Cluster API | Enables the Cluster API for a database When this option is enabled, you cannot define a custom hashing policy. |
To learn more about these settings and when to use them, see Database clustering.
Durability section
The Durability section helps you keep your database (and your data) available when problems occur.

Setting name | Description |
---|---|
Data persistence | Defines whether (and how) data is saved to disk; available options depending on your plan type |
Data eviction policy | Configures which policy is applied when your database reaches its memory limit |
Remote backup | When enabled, identifies a location and interval for data backups |
Active-Passive Redis | When enabled, identifies a path to the linked database. See Migrate data for more information. |
Tags section
The Tags section lets you add tags to the database.

Select Add tag to add a tag.

You can select the tag's Key and Value from the suggestions, or you can enter your own.

A valid tag must follow these guidelines:
- Tag keys must be between 1 and 64 characters long, and values must be at least 1 character long.
- Tags can only have lowercase letters, numbers, spaces, and these special characters:
-
,_
,.
,+
,@
, and:
.
After you add your first tag, you can:
-
Select the Key or Value field of an existing tag and enter new text to edit it.
-
Select Delete next to a tag to delete it.
-
Select Add additional tag to add another tag.
Security section
The Security section helps you control access to your database.

Setting name | Description |
---|---|
Default user | When enabled, permits access using a simple password |
Redis password | Password assigned to the database when created |
CIDR allow list | Allow list of IP addresses/security groups permitted to access the database |
Transport layer security (TLS) | Enables transport layer security (TLS) encryption for database access |
Alerts section
The Alerts section defines notification emails sent to your account and the conditions that trigger them.

The available alerts vary according to the subscription type.
Setting name | Description |
---|---|
Dataset size has reached | When enabled, sends an an email when the database reaches the defined memory limit |
Latency is higher than | When enabled, sends an an email when the latency exceeds the defined limit |
Replica Of - database unable to sync with source | When enabled, sends email when the replica database cannot sync with the primary (source) database |
Replica Of - sync lag is higher than | When enabled, sends email when the sync lag exceeds the defined threshold |
Throughput is higher than | When enabled, sends an email when the operations per second exceed the defined threshold |
Throughput is lower than | When enabled, sends an email when the operations per second falls below the defined threshold |
Billing Unit types
The Redis Billing Unit types associated with your Pro subscription depend on your database memory size and throughput requirements.
Billing unit type | Capacity (Memory/Throughput) |
---|---|
Pico | 100MB / 100 ops/sec |
Nano | 500MB / 500 ops/sec |
Micro | 1GB / 1K ops/sec |
High-throughput | 2.5GB / 25K ops/sec |
Small | 12.5GB / 12.5K ops/sec |
Large | 25GB / 25K ops/sec |
Very large1 | 50GB / 5K ops/sec |
XLarge2 | 50GB / 10K ops/sec |
Prices vary according to the cloud provider and region. Minimum prices apply. To learn more, see Cloud pricing.
