Highlights

This new release introduces significant features, improvements, and fixes.
A critical fix is that the server will crash when using ZRANDMEMBER for non-existent keys, please see #2982.

We introduce a few new commands and enhance some old commands, including:

  • CLIENT REPLY to allow clients to control server reply behavior
  • KPROFILE to enable/disable/dump the memory profiling
  • FLUSHMEMTABLE to flush memtables
  • FLUSHBLOCKCACHE to explicitly release the block cache

Another highlight is that the community is working to support the TDIGEST data structure, but we don't bring it to this release for stable consideration.

New Features

  • feat(cmds): Add support for CLIENT REPLY subcommand and related tests by @DCjanus in #2943
  • feat(tdigest): Add support for QUANTILE command by @SharonIV0x86 in #2849
  • feat(command): add a new command to enable/disable/dump the memory profiling by @git-hulk in #3007
  • feat(command): Add redis command to flush memtables by @Ryan4253 in #3022
