Altinity Kubernetes Operator 0.21.1 Release Notes

Added

• Added configurable shard-level concurrent reconciliation by @zcross in https://github.com/Altinity/clickhouse-operator/pull/1124. It is controlled by the following operator configuration settings:

reconcile:
  runtime:
    # Max number of concurrent CHI reconciles in progress
    reconcileCHIsThreadsNumber: 10
    # Max number of concurrent shard reconciles in progress
    reconcileShardsThreadsNumber: 1
    # The maximum percentage of cluster shards that may be reconciled in parallel
    reconcileShardsMaxConcurrencyPercent: 50

• Added default configuration for ClickHouse system.trace_log table with 30 days TTL

Changed

• ZooKeeper manifests were rewritten to store configuration separately

Fixed

• Fixed a bug in metrics-exporter that might stop working on ClickHouse nodes with certain types of system.errors. Closes #1161
• Fixed a bug with ClickHouse major version detection for Altinity.Stable builds
