Redis 8.2 released with performance boosts, new streams data structure commands, and more

Redis has announced the general availability of version 8.2, introducing substantial improvements for performance and efficiency, including up to 35% faster command execution and as much as 49% higher operations per second. Building on these enhancements, the release employs a new internal storage method for keys and JSON values, which can reduce memory usage by up to 67% for workloads with significant key and document storage.

For developers, Redis 8.2 streamlines workflows with new commands for manipulating stream data structures, reflecting features asked for by the community. Alongside this, the update adds advanced BITOP operators, enabling more complex bitwise operations to be completed with fewer commands and less client-side processing.

Redis 8.2 ensures full backward compatibility with the widely used Jedis, Lettuce, go-redis, node-redis, NRedisStack, and redis-py client libraries. Support extends to the Redis OM clients for object mapping, RedisVL for vector search applications, Redis Insight, and Redis for Visual Studio Code, allowing users to upgrade without disruptions or toolchain changes.
