Highlights

Added WAIT — Blocks after a write until N replicas acknowledge (or timeout), returning the ack count. Enables synchronous-style replication for stronger durability and consistency in Kvrocks.

Added T-Digest — Probabilistic data type for fast, memory-efficient approximate percentiles on streams and large datasets. Ideal for latency histograms, telemetry, and anomaly detection. See supported commands.

Lua scripting: strict key-access mode — Enforces access only to keys declared via EVAL/FCALL. In this mode the global lock is removed, delivering much higher concurrency and throughput. Recommended for workloads that heavily use Lua scripts.

Dep Updates — RocksDB is upgraded to version 10.6.2 in this release.

Other notable updates — Added RISC-V support; significant replication performance/stability improvements; and Search enhancements, including a compaction filter and skipping expired keys during queries.

Important Notice

This new release introduces significant features, improvements, and fixes.

Dependency Updates: RocksDB version bumps from 8.11.4 to 9.6.1.

2.9.0

Important Notice

This new release introduces significant features, improvements, and fixes.

Numerous new commands are now supported, such as DUMP, SORT, LCS, COPY, ASKING, READONLY, and READWRITE. These additions enhance Kvrocks' capabilities by improving data migration and cluster features. A big thank you to all contributors for their valuable input to Kvrocks.

The default value of CMake option ENABLE_NEW_ENCODING is set to ON, which means the new data type encoding (specified here) is enabled by default while all old data is still compatible. (Note: After you upgrade to Kvrocks 2.9.0 and write new data, if you roll back Kvrocks to 2.3.0 or earlier versions, these newly-written data will not be available.)

Async IO in RocksDB is enabled by default since this release which might bring the performance benefit for the scan behavior if the io uring is supported.

In addition, the config option compaction-checker-range is still available but is marked as deprecated. We recommend using compaction-checker-cron instead. Also, the cron syntax in the config file has been extended. For example, you can now use cron expressions like * */2 1,3-6,8 * *.

Kvrocks Search (compatible with both SQL and RediSearch queries) and stream groups are two experimental new features that are already available in the unstable branch, but they are not enabled in this release.

RocksDB is still in version 8.11 (8.11.4) for this version. However, in the next feature release, we plan to bump RocksDB to version 9.

New Features

  1. Add the support of the LCS command by @JoverZhang in #2116
  2. Add compression level option by @Beihao-Zhou in #2171
  3. Add support of READONLY and READWRITE by @LiuYuHui in #2173
  4. Support value setting for nonexistent paths in JSON.SET by @PragmaTwice in #2178
  5. Add BIT support to BITPOS by @sheharyaar in #2170
  6. Add support of the command MOVEX by @Chiro11 in #2225
  7. Add support of the command DUMP by @AntiTopQuark in #2227
  8. Add support of the command JSON.MSET by @zjregee in #2228
  9. Add support of the SORT command by @PokIsemaine in #2262
  10. Support ASKING command by @jjz921024 in #2273
  11. Add support of the command JSON.DEBUG MEMORY by @jackyyyyyssss in #2323
  12. Enable the rocksdb async io by default by @xiaobiaozhao #2308

Important Notice

Dependency Updates: RocksDB is bumped from 8.8.1 to 8.11.3 in this version.

Highlights:

Set the default value of redis-cursor-compatible to yes, so from this version, Kvrocks' SCAN will be compatible with Redis by default. We also proudly announce that RESP3 is fully supported now, you can enable the RESP3 feature via set resp3-enabled yes.

In addition, the cluster now can use the rocksdb write-batch to migrate slot data between instances via the APPLYBATCH command, which is faster and consumes less CPU compared to the replay command way.

It is worth mentioning that the community is working on the RedisSearch module, and we look forward to seeing RedisSearch in a future release.
