Altinity Kubernetes Operator ClickHouse Files

Changed

• Hosts are not excluded from remote_servers anymore if restart is not needed. Previously, replicas in replicated cluster might be removed for a short time even if restart was not needed.
• configuration.zookeeper section changes do not require restart anymore
• Last reconciliation error and list of errors are now stored in CHI status

Fixed

• actionPlan is now optional in status. That fixes operator upgrade problems that might happen in some environments.
• Fixed excessive reconciles triggered by endpoint slices. Closes https://github.com/Altinity/clickhouse-operator/issues/1873
• Fixed crash in CHK that might happen sometimes. Closes https://github.com/Altinity/clickhouse-operator/issues/1863
• Fixed an issue with handling fractional requests/limits that would result in excessive reconcile. Closes https://github.com/Altinity/clickhouse-operator/issues/1849 https://github.com/Altinity/clickhouse-operator/issues/1821
• Fixed a bug with operator crash in Terminating namespace. Closes https://github.com/Altinity/clickhouse-operator/issues/1871
• stdlib was upgraded in order to address CVEs in dependent libraries

NOTE: Due to regression in upstream ClickHouse https://github.com/ClickHouse/ClickHouse/issues/89693 schema propagation and DDL statements do not work with ClickHouse versions 25.8.10+ and newer until it is resolved.
