    upstream-bot released this 2026-11-04 15:36:35 -05:00 | 11 commits to main since this release

    KeyDB 6.3.4 Release Notes:

    • Add keydb_modstatsd, a module for providing keydb stats to a local statsd server. Can be found under src/modules/keydb_modstatsd
    • Fixed FreeBSD compile(Thanks to @bra-fsn)
    • Fixed a bug in s3 bucket config that blocked startup(Thanks to Alexandre Chichmanian)
    • Fixed a bug causing crash if keys command is called after a blocking command (Fixes issues #659, #605, #532)
    • Added proper error checking of replica configs, now KeyDB will throw an error if replica-of config is passed before active-replica or multimaster configs
    • Fixed double free bug in lazy free
    • Added "overload-protect-percent" config, when enabled this will load shed clients whenever CPU usage exceeds configured value
    • Added "availability-zone" config, this can be passed any string which will then be reported by info command
    • Updated eviction logic to account for total system memory availability using sysinfo
    • Fixed a bug where repl-backlog-size config was modified in keydb.conf with the runtime value during config rewrite
    • Fixed a possible deadlock when running CLIENT KILL with large number of clients
    • Fixed a bug where KeyDB would overcommit memory during fork BG save
    • Fixed a bug with disk repl_backlog causing double free
    • Fixed integer overflow issue in the temp rdb file naming (Thanks to @karthyuom)
    • Fixed compile issue with GCC 13.1.1 (Thanks to @michieldwitte)
    • Removed expireset and restored redis expire behaviour
    • Fixed a bug causing forked processes to hang, specifically affecting RDB and AOF(Fixes issues #675, #619)
    • Added "CLUSTER REPLICATE NO ONE" to turn a replica into an empty primary
    • Added RDB-less full sync, can be enabled with config 'enable-keydb-fastsync'

    FLASH(Beta):

    • Added "flash-disable-key-cache" config to disable key cache which stores every key(but not value) in memory
    • Moved cluster slot to key map to being stored by storage provider, rather than in memory
    • Moved expires to be stored by storage provider, rather than in memory
    • Enabled expiry/eviction from storage provider, previously only data stored in memory could be expired/evicted(Fixes #645 along with the 2 previous updates)
    • Fixed a bug where swapdb result was not recovered after keydb restarts in FLASH mode (Thanks to @karthyuom)
    • Fixed double free bug when fast sync was canceled early
    • Fixed a bug where a temp rdb file with zero bytes is generated in flash mode (Thanks to @karthyuom)
