Future Redis releases will continue to offer free and permissive use of the source code under dual RSALv2 and SSPLv1 licenses; these releases will combine advanced data types and processing engines previously only available in Redis Stack. Beginning today, all future versions of Redis will be released with source-available licenses. Starting with Redis 7.4, Redis will be dual-licensed under the Re
Operate Redis Community Edition and Redis Stack. Redis OSS was renamed Redis Community Edition (CE) with the v7.4 release.
Today we’re thrilled to announce Redis Stack. Redis Stack consolidates the capabilities of the leading Redis modules into a single product, making it easy for developers to build modern, real-time applications with the speed and stability of Redis. Prologue At Redis, we’re building a real-time data layer to meet the universal demand for responsive, low-latency applications and services. To build a
Note: this post has been edited to reflect the general availability of Redis JSON 2.0 and Redis Search 2.2 In July 2019, we introduced the private preview of a real-time document store with native indexing, querying, and full-text search capabilities powered by the combination of Redis JSON and Redis Search. During the preview, we’ve greatly improved the performance and stability of the offering,

Name change reflects the central role the company maintains in leading the evolution of open source Redis from a popular caching system into the leading real-time data platform Mountain View, August 11, 2021—Today, Redis Labs announced the company is now registered as Redis, dropping “Labs” from its name. The change signals the maturation of the company and the Redis open source project, which it
Download the JSON Web Tokens (JWTs) are not safe e-book here Sometimes, people take technologies that are intended to solve a narrow problem and start applying them broadly. The problem may appear similar, but utilizing unique technologies to solve general issues could create unanticipated consequences. To use a metaphor, if you are a hammer, everything looks like a nail. JWT is one such technolog

Your scientists were so preoccupied with whether or not they could, they didn’t stop to think if they should.—Dr. Ian Malcolm, in Jurassic Park “Best Practices” has become a trope in technology. Sure, you can do something with a given tool, but is doing so really a good i
Server-assisted, client-side caching in Redis Client-side caching is a technique used to create high performance services. It exploits the memory available on application servers, servers that are usually distinct computers compared to the database nodes, to store some subset of the database information directly in the application side. Normally when data is required, the application servers ask t

Well, the new Redis 6 is no shallow update to the world’s most-loved database—it’s so deep you can dive right in. Now that Salvatore Sanfilippo has made Redis 6 generally available, let’s take a dip in the new changes and features. The new stuff can be divided into a few dif
It’s that time of the year again. No, I’m not referring to the winter holidays, but to the reverberations of the announcements coming out of AWS re:Invent. Oftentimes when AWS makes a big move, IT ecosystems get shaken. In the database space, this year the effect focused on Apache Cassandra, after AWS announced a Cassandra-compatible serverless managed solution. Along with the announcement, AWS al
JSON support for Redis The JSON capability of Redis Stack provides JavaScript Object Notation (JSON) support for Redis. It lets you store, update, and retrieve JSON values in a Redis database, similar to any other Redis data type. Redis JSON also works seamlessly with Search and Query to let you index and query JSON documents. Primary features Full support for the JSON standard A JSONPath syntax f

It enables users to execute complex search queries on their Redis dataset in an extremely fast manner. The unique architecture of RediSearch, which was written in C and bui
Since the recent licensing change for our Redis modules, there’s been a lot of confusion and misinformation circulating about the implications of those changes. We want to address your questions and be crystal clear: the license for open source Redis was never changed. It is BSD and will always remain BSD. So what has changed? We recently did change the license for Redis modules developed by Redis
FAQs Why are you offering a dual license strategy? We believe the permissive approach of RSALv2 and the standard wording we use to define its limitations solves many of the challenges raised by our community, but we are also aware that, like any newly created license, it will take time for some users (and their legal teams) to digest it and therefore we’ve added an option to use SSPL.

I’ve been using Redis for about six years now, and over the years I’ve exploited its few data types to do some pretty versatile things such as geographical queries, text search, machine learning and more. But over the years, I can’t even count the number of times I’ve found myself (as did many other users) wishing that Redis would have this or other data structure, command or capability it is lack
For those of you familiar with Redis, it should be relatively straightforward to create a configuration that guarantees ACID-ish (Atomicity, Consistency, Isolation, Durability) operations: merely create a single Redis instance with a ‘master’ role and have it configured with AOF every write (‘appendfsync always’) to a persistent storage device. This configuration provides ACID characteristics in t
Introduction to writing Redis modules The modules documentation is composed of the following pages: Introduction to Redis modules (this file). An overview about Redis Modules system and API. It's a good idea to start your reading here. Implementing native data types covers the implementation of native data types into modules. Blocking operations shows how to write blocking commands that will not r
Overview of redis-cli, the Redis command line interface In interactive mode, redis-cli has basic line editing capabilities to provide a familiar typing experience. To launch the program in special modes, you can use several options, including: Simulate a replica and print the replication stream it receives from the primary. Check the latency of a Redis server and display statistics. Request ASCII-

Redis modules are add-ons to Redis that extend Redis to cover most popular use cases in a wide variety of industries. They seamlessly plug into Redis, are processed in-memory, and provide Redis’ simplicity, super high performance, scalability, and high availability. Modules can be created by anyone. With Redis modules you adapt your database to your data rather than the other way around. Use Redi

Discovering slow server events in Redis Redis is often used for demanding use cases, where it serves a large number of queries per second per instance, but also has strict latency requirements for the average response time and the worst-case latency. While Redis is an in-memory system, it deals with the operating system in different ways, for example, in the context of persisting to disk. Moreover
