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.

NOTICE: JSON and BloomFilter is not ready for the cluster mode yet.
