v8.0.0

Compare Source

This is the General Availability release of Redis Open Source 8.0.

Redis 8.0 deprecates previous Redis and Redis Stack versions.

Stand alone RediSearch, RedisJSON, RedisTimeSeries, and RedisBloom are no longer needed as they are now part of Redis.

Major changes compared to 7.4.2
  • Name change: Redis Community Edition is now Redis Open Source

  • License change: licensed under your choice of

    • (a) the Redis Source Available License 2.0 (RSALv2); or
    • (b) the Server Side Public License v1 (SSPLv1); or
    • (c) the GNU Affero General Public License (AGPLv3)
  • Redis Query Engine and 8 new data structures are now an integral part of Redis 8

    • (1) Redis Query Engine, which now supports both horizontal and vertical scaling for search, query and vector workloads

    • (2) JSON - a queryable JSON document

    • (3) Time series

    • (4-8) Five probabilistic data structures: Bloom filter, Cuckoo filter, Count-min sketch, Top-k, and t-digest

    • (9) Vector set [beta] - a data structure designed for Vector Similarity Search, inspired by Sorted set

    • These nine components are included in all binary distributions

    • See instructions in the README.md file on how to build from source with all these components

    • New configuration file: redis-full.conf - loads Redis with all these components,
      and contains new configuration parameters for Redis Query Engine and the new data structures

    • New ACL categories: @search, @json, @timeseries, @bloom, @cuckoo, @cms, @topk, @tdigest

    • Commands are also included in the existing ACL categories (@read, @write, etc.)

  • More than 30 performance and resource utilization improvements

  • A new I/O threading implementation which enables throughput increase on multi-core environments
    (set with io-threads configuration parameter)

  • An improved replication mechanism which is more performant and robust

  • New hash commands - HGETDEL, HGETEX, HSETEX

For more details, see the release notes of 8.0-M01, 8.0-M02, 8.0-M03, 8.0-M04, and 8.0-RC1
