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.
