Yandex Managed Service for ClickHouse® release notes

December 2025

  • Added detailed metrics for disk usage on cluster hosts.

  • ClickHouse® Keeper coordination service running on separate hosts is billable. It works faster than ZooKeeper and uses the Raft consensus algorithm. This configuration is recommended for the production environment.
  • Released a new ClickHouse® version: 25.11.

November 2025

  • ClickHouse® Keeper is now available to all Managed Service for ClickHouse® users and used by default in new clusters. In addition, now you can create separate hosts with ClickHouse® Keeper in your cluster. To learn more about ClickHouse® Keeper, see Replication.
  • Added the managed-clickhouse.restorer role for restoring clusters from backups. To learn more, see Access management.

  • The Failed insert queries per host, Failed queries per host, and Failed select queries per host charts now show the percentage of failed queries rather than their number.
  • The Max replication queue across tables chart now shows the total replication queue of all tables and is called Replication queue.
  • Renamed the following charts:
    • CPU → CPU usage.
    • Disk bytes → Disk read/write bytes.

  • Made the following parameters optional for the yc managed-clickhouse cluster restore command:

    • --name
    • --description
    • --host
    • --user

    Unless these parameters are explicitly specified, their values will be taken from the source cluster. At the same time, ClickHouse® and ZooKeeper hosts will have the same configuration as in the source cluster once restored. ClickHouse® hosts will only be restored for the shards whose backups are selected for restoration.

Q2 2022

  • The new ClickHouse® version is out: 22.5 (see the changelog).
