Upgrading Redis modules via rladmin

The rladmin CLI introduces several updates to the commands for upgrading modules. It is now easier to upgrade your modules to the latest module version. Find out more here.

Redis modules

The following GA releases of Redis Modules are bundled in RS 6.0:

To use the updated modules with a database, you must upgrade the module on the database.

Additional capabilities

  • Shard level metrics have been added to the metrics_exporter and are now available from Prometheus. You can find all of the metrics here.
  • The crdb-cli history log is now being added to support packages.

Important fixes

  • RS33193 - Improved log files handling in the proxy for large files.
  • RS43572 - Fixed a bug causing the UI to fail when enabling SMTP STARTLS.

  • RS44758 - Fixed non responding button for saving a new user via the UI.

Known limitations

Upgrade

  • RS 5.4.2 introduced new Active-Active Redis Database capabilities that improve its compatibility with open source Redis. Now the string data-type in Active-Active Redis Database is implicitly and dynamically typed, just like open source Redis. To use the new capabilities on nodes that are upgraded from version RS 5.4.2 or lower, you must upgrade the Active-Active Redis Database protocol.
  • When you upgrade an Active-Active Redis with active AOF from version RS 5.4.2 or lower to version RS 5.4.2 or higher:
    • If replication is enabled, you must run the BGREWRITEAOF command on all slave shards after the upgrade.
    • If replication is not enabled, you must run the BGREWRITEAOF command on all shards after the upgrade.
  • Node upgrade fails if the SSL certificates were configured in version 5.0.2 or above by manually updating the certificates on the disk instead of updating them through the API. For assistance with this issue, contact Support.
  • Starting from RS 5.4.2, to preserve the current Redis major.minor version during database upgrade you must use the keep_redis_version option instead of keep_current_version.

Redis commands

  • The capability of disabling specific Redis commands does not work on commands specific to Redis Modules.
  • Starting from RS 5.4.2 and after you upgrade an Active-Active database, TYPE commands for string data-type in Active-Active databases return “string” (OSS Redis standard).
