release-0.25.0
Added
- Multiple service templates are now supported for a single purpose. Example of syntax:
defaults:
templates:
serviceTemplates:
- service-template
- service-template-internal
- Added availabilityZone attribute for ZooKeeper spec:
configuration:
zookeeper: # Add Zookeeper
nodes:
- host: zookeeper
port: 2181
availabilityZone: "my-azone"
- Operator can now inject version specific ClickHouse configuration, it is configured in 'addons' section of operator configuration. This closes #1603 but can be used for other use cases as well
- Added an option to specify reconciling.runtime.reconcileShardsThreadsNumber and reconcilingShardsMaxConcurrencyPercent on the CHI level
- [Helm] ServiceMonitor additional configuration by @nlamirault in #1624
- [Helm] Add namespace override capability for multi-namespace deployments by @bwdmr in #1640
- [Helm] Add common labels and annotations to all resources by @dashashutosh80 in #1692
- [Helm] Add support for rbac at namespace scope in @dashashutosh80 #1698
Changed
- When a new cluster is started with reconcilingShardsMaxConcurrencyPercent=100, all shards are created in parallel. Previously, first shard was always created alone.
- The new option to wait for replication to catch up when adding a new replica is enabled by default. It can be configured in operator reconcile settings:
reconcile:
host:
wait:
replicas:
all: no
new: yes
delay: 10
Fixed
- Fixed a bug with underlying replicated tables were not properly created when adding new nodes sometimes. Closes #1689
- Fixed a bug when service was not updated if clusterIP is changed from missing to None in service template
- Fixed a bug when annotations were not removed from service if removed from service template

release-0.24.5
What's Changed
- Follow-up to the previous release. CLICKHOUSE_SKIP_USER_SETUP is not added if default entrypoint is not used.
- Fixed a bug when ClickHouseOperatorConfiguration was not correctly merged sometimes
- Adjusted default configuration so configuration files with 'no_restart' in the file name would not cause ClickHouse restarts
- Changed how operator handles remote_servers.xml when doing rolling updates. Now instead of removing/adding a replica, it sets low priority to make sure replica does not get any traffic from distributed queries
- Bumped dependencies to address CVE-2025-22868 and CVE-2025-22870
- Fixed a typo in Keeper Prometheus alert by @morkalfon in #1657

ClickHouseInstallationandClickHouseKeeperreconciliation by @a7i in #1580. Controlled by.spec.suspendattribute. Closes #1433 - New clickhouse_operator_chi metric in metrics-exporter

Changed
- NormalizedCHI that is used to plan reconciliation was moved from CHI status to a separate configmap object. Closes #1444
- Changed a way ClickHouse is restarted in order to pickup server configuration change. Instead of pod re-creation it tries
SYSTEM SHUTDOWNfirst. That speeds things up on nodes with big volumes, since those should not be re-attached. - Unused fields 'HostsUnchanged' and 'HostsDelete' were removed from extended status output
- Upgrade prometheus-operator to 0.79.0 (alerts tested with prometheus 3.0.1) by @Slach in #1599

release-0.24.0
BACKWARD INCOMPATIBLE CHANGES
- ClickHouseKeeper support has been completely re-written. It is now fully compatible with CHI in syntax and supported functionality that closes multiple issues discovered by early adopters. The downside is that CHK resources created by operator 0.23.x will loose the storage and change service name due to different naming conventions.
See CHK upgrade instructions from 0.23 to 0.24 for detail.
This closes #1504, #1497, #1469, #1465, #1459, #1408, #1362, #1296
Added
- Added 'pdbMaxUnavailable' attribute to the cluster to manage PDB behavior. See 01-simple-layout-03-multiple-clusters-pdb-spec.yaml
- Added 'all-clusters' cluster into auto-generated remote_servers.xml that references multiple clusters in CHI with respect to shards and replicas. by @tanner-bruce in #1409
Changed
- Operator will now create zookeeper root path if specified in CHI configuration. Previously it assumed root path already exists.
- Operator now waits for the last host to be included in the cluster before marking CHI as completed
- Update helm chart to allow add pod labels by @bruno-s-coelho in #1359. Closes #1356
- Support install operator from local template by @orloffv in #1401
- Added prometheus zeros init for reconciliation metrics by @nmiculinic in #1398
- Update helm chart to allow adding topologySpreadConstraints by @naturalett in #1462
- Use ConfigMap instead of Secret for grafana dashboards by @cwrau in #1457
- Altinity_ClickHouse_Operator_dashboard.json: dashboard has been updated by @nmiakushina in #1512 and #1515
