Redis® 7 is here illustration

Redis® 7.0 introduces improvements to almost every aspect of the popular open source database. Here’s some of the most notable new features:

  • Enhanced scripting with Redis Functions
  • Improved access control management with ACLv2
  • The addition of almost 50 new commands

At the same time, a lot of effort has gone into making Redis even more performant and stable than before.

Redis Functions brings a new solution for scripting in Redis, allowing users to load custom function libraries to Redis. Unlike earlier ephemeral scripts using the EVAl command, which left management of the scripts to the applications, Redis now manages functions as an integral part of the database and ensures their availability through data persistence and replication.

ACLv2 adds two important new capabilities for access control lists, while maintaining compatibility with earlier versions:

  • ACLv2 adds support for multiple sets of ACL rules - called selectors - that are evaluated independently.
  • ACLv2 allows you to set access type permissions to specific keys, making it possible to to exclusively limit the user to read-only, write-only, or read-write operations to a subset of the keys.

Please note that ACLv2 is not yet available in Aiven for Redis®, but we are working on it and expect to release the functionality soon.

Redis version 7.0 adds almost 50 new commands and options to support the evolution of Redis, and to extend its existing capabilities. And the following data types, just for example, all have added functionality that supports their use cases for data management:

  • bitmap
  • list
  • set
  • sorted set
  • stream

If you already use Aiven for Redis, you can upgrade as you see fit. Otherwise, your service will be upgraded in specific cases - like if you change your current plan or the replacement of a node upon failure.

If you’re not using Aiven for Redis yet, maybe you should be! Go ahead and read more about Redis in our Introduction to Redis, or visit our Redis page to get started.
