*Programming with Redis

  • The full list of commands implemented by Redis, along with thorough documentation for each of them.
  • Pipelining: Learn how to send multiple commands at once, saving on round trip time.
  • Redis Pub/Sub: Redis is a fast and stable Publish/Subscribe messaging system! Check it out.
  • Redis Lua scripting: Redis Lua scripting feature documentation.
  • Debugging Lua scripts: Redis 3.2 introduces a native Lua debugger for Redis scripts.
  • Memory optimization: Understand how Redis uses RAM and learn some tricks to use less of it.
  • Expires: Redis allows to set a time to live different for every key so that the key will be automatically removed from the server when it expires.
  • Redis as an LRU cache: How to configure and use Redis as a cache with a fixed amount of memory and auto eviction of keys.
  • Redis transactions: It is possible to group commands together so that they are executed as a single transaction.
  • Client side caching: Starting with version 6 Redis supports server assisted client side caching. This document describes how to use it.
  • Mass insertion of data: How to add a big amount of pre existing or generated data to a Redis instance in a short time.
  • Partitioning: How to distribute your data among multiple Redis instances.
  • Distributed locks: Implementing a distributed lock manager with Redis.
  • Redis keyspace notifications: Get notifications of keyspace events via Pub/Sub (Redis 2.8 or greater).
  • Creating secondary indexes with Redis: Use Redis data structures to create secondary indexes, composed indexes and traverse graphs.

*Redis modules API

  • Introduction to Redis modules. A good place to start learing about Redis 4.0 modules programming.
  • Implementing native data types. Modules scan implement new data types (data structures and more) that look like built-in data types. This documentation covers the API to do so.
  • Blocking operations with modules. This is still an experimental API, but a very powerful one to write commands that can block the client (without blocking Redis) and can execute tasks in other threads.
  • Redis modules API reference. Directly generated from the top comments in the source code inside src/module.c. Contains many low level details about API usage.

*Tutorials & FAQ


  • Quick Start: How to quickly install and configure Redis. This targets people without prior experience with Redis.
  • Redis-cli: Learn how to master the Redis command line interface, something you'll be using a lot in order to administer, troubleshoot and experiment with Redis.
  • Configuration: How to configure redis.
  • Replication: What you need to know in order to set up master-replicas replication.
  • Persistence: Know your options when configuring Redis' durability.
  • Redis Administration: Selected administration topics.
  • Security: An overview of Redis security.
  • Redis Access Control Lists: Starting with version 6 Redis supports ACLs. It is possible to configure users able to run only selected commands and able to access only specific key patterns.
  • Encryption: How to encrypt Redis client-server communication.
  • Signals Handling: How Redis handles signals.
  • Connections Handling: How Redis handles clients connections.

*Embedded and IoT


*Redis Cluster

*Other distributed systems based on Redis

  • Redis CRDTs an active-active geo-distribution solutions for Redis.
  • Roshi is a large-scale CRDT set implementation for timestamped events based on Redis and implemented in Go. It was initially developed for the SoundCloud stream.

*Redis on SSD and persistent memory

  • Redis on Flash by Redis Ltd. extends DRAM capacity with SSD and persistent memory.



*Use cases


The following is a list of books covering Redis that are already published. Books are ordered by release date (newer books first).

The following books have Redis related content but are not specifically about Redis:


Redis is developed and maintained by the Redis community.

The project was created, developed and maintained by Salvatore Sanfilippo until June 30th, 2020. In the past Pieter Noordhuis and Matt Stancliff provided a very significant amount of code and ideas to both the Redis core and client libraries.

The full list of Redis contributors can be found in the Redis contributors page at Github. However there are other forms of contributions such as ideas, testing, and bug reporting. When it is possible, contributions are acknowledged in commit messages. The mailing list archives and the Github issues page are good sources to find people active in the Redis community providing ideas and helping other users.


The work Salvatore Sanfilippo does in order to develop Redis is sponsored by Redis Ltd. Other sponsors and past sponsors of the Redis project are listed in the Sponsors page.
