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

Dependency Updates: RocksDB version bumps from 8.11.4 to 9.6.1.

Highlights

The new data structure HyperLogLog and its commands are supported now, users can use PF* commands in Kvrocks. Thanks to contributors: @mapleFU @tutububug.

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.

2.8.0

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.

2.7.0

Important Notice

Dependency Updates: RocksDB is bumped from 8.3.3 to 8.8.1 in this version.

Highlights:

We're thrilled to announce that the JSON data structure is supported now, huge thanks to @PragmaTwice and all contributors for making this happen. Also, basic capabilities of Functions have been supported to make up for the lack of modularity of the EVAL-series commands.

From this release, the speedb is allowed to be used as an alternative to rocksdb, you have a try as simple as to append the build option -DENABLE_SPEEDB=ON. Additionally, dynamic change number of worker threads is also supported and users can change it via CONFIG SET workers {NUMBER}. Furthermore, numerous new commands and bug fixes have been implemented.

Important Notice

Dependency Updates: RocksDB is bumped from 8.3.2 to 8.3.3 in this version.

Full Changelog: v2.4.0...v2.5.0-rc2

2.4.0

Note: In this release, we have upgraded RocksDB to version 8.1.1. In addition, we have introduced a new storage encoding format that can accommodate 64-bit element count and expiration time in milliseconds. To enable this feature, you must include -DENABLE_NEW_ENCODING=ON during the build process (which is not enabled by default). Once the new encoding is enabled, data stored using the old encoding will remain accessible for reading and writing as usual. However, any new data will be written using the new encoding format.
