版本变更

弃用

watchdog_profile

这watchdog_profile设置已弃用，并将在未来发行版中删除。相反，请使用failure_detection_sensitivity预定义阈值和超时的策略：

rladmin tune cluster failure_detection_sensitivity [ high | low ]

The failure_detection_sensitivity policy has the following options:

  • high (previously known as local-network watchdog_profile) – high failure detection sensitivity, lower thresholds, and faster failure detection and failover

  • low (previously known as cloud watchdog_profile) – low failure detection sensitivity and higher tolerance for latency variance (also called network jitter)

Ubuntu 16.04

Ubuntu 16 support is deprecated, and support will be removed in a future release.

Active-Active database persistence

The RDB snapshot option for Active-Active database persistence is deprecated and will be removed in a future release.

Please plan to reconfigure any Active-Active databases to use append-only file (AOF) persistence with the following command:

crdb-cli crdb update --crdb-guid <CRDB_GUID> \
    --default-db-config '{"data_persistence": "aof", "aof_policy":"appendfsync-every-sec"}'

Resolved issues

  • RS97528 - Prevent self-signed certificate script error on Ubuntu 20.04 by changing the user instructions.

  • RS99643 - Fix cipher_suites configuration to allow default cipher suites according to the control plane, data plane, and discovery service.

  • RS99696 - Fix HINCRBYFLOT CVE

  • RS54226 - During upgrades, a CRDB worker process would intermittently get stuck in a restart loop. This issue is now fixed.

Known limitations

Feature limitations

  • RS78430 - When tuning module arguments, any typo or use of unsupported arguments can cause shards to get stuck after restart.

Operating system limitations

Ubuntu 20.04

By default, you cannot use the SHA1 hash algorithm (OpenSSL’s default security level is set to 2). The operating system will reject SHA1 certificates even if the mtls_allow_weak_hashing option is enabled. You need to replace SHA1 certificates with newer certificates that use SHA-256. Note that the certificates provided with Redis Enterprise Software use SHA-256.
