After returning to the open source family<\/a> in early May, Redis, a distributed in-memory key-value data store, officially rolled out version 8.2 a few days ago, building on the foundation set by Redis 8.0<\/a>.<\/p>\n\n\n\n

The headline figures are more than impressive: This update offers up to 35% faster command execution, 49% higher throughput\u2014surpassing one million operations per second on a single instance\u2014and memory savings of up to 67% in certain scenarios.<\/p>\n\n\n\n

Moreover, Redis 8.2 optimizes over 70 commands, with notable standouts like BITCOUNT<\/code> running 35% faster and list operations (LINSERT<\/code>, LREM<\/code>, LPOS<\/code>) seeing latency drops of more than 25%. Thanks to enhancements in I\/O threading, Redis 8.2 can handle nearly half again as many operations per second compared to 8.0 for workloads with a mix of reads and writes.<\/p>\n\n\n\n

On the memory side, Redis now employs a unified key-value object structure that tightly packs keys, values, and optional TTL data into a single memory allocation. This architectural shift not only reduces pointer overhead but also slashes memory usage for short string keys by 25\u201337%.<\/p>\n\n\n\n

JSON storage gets even more dramatic improvements: for numeric values, memory consumption drops by as much as two-thirds, which could have a big impact for data-heavy use cases like financial records or analytics workloads.<\/p>\n\n\n\n

Apart from that, Redis Streams, which are widely used for event-driven architectures, now come with two new commands\u2014XACKDEL and XDELEX\u2014that make it far easier to manage multi-consumer groups without elaborate application logic.<\/p>\n\n\n\n

Lastly, bitmap users also get an upgrade with four new logical operators for the BITOP<\/code> command\u2014DIFF<\/code>, DIFF1<\/code>, ANDOR<\/code>, and ONE<\/code>\u2014allowing more complex set operations in a single step. As our readers who bet on Radis know, these could prove especially useful in scenarios like gaming, ad targeting, or tracking user membership in various categories.<\/p>\n\n\n\n

Redis 8.2 remains fully compatible with popular client libraries, including Jedis, Lettuce, go-redis, node-redis, NRedisStack, and redis-py. The same goes for Redis OM, RedisVL for AI workflows, and tools like Redis Insight and the Redis VS Code extension.<\/p>\n\n\n\n

For more information, see the announcement<\/a>. Redis 8.2 is available now via Docker Hub (Alpine or Debian images), Snap, Homebrew, RPM, and APT.<\/p>\n\n\n\n
