Altinity/clickhouse-operator release-0.25.5

on GitHub

Added

• The latest applied ActionPlan is now stored in chi-storage ConfigMap
• volumeClaimTemplate.volumeAttributeClass attribute. Closes #1818
• Configuration for DROP REPLICA behavior:

reconcile:
   host:
    drop:
      replicas:
        # Whether the operator during reconcile procedure should drop replicas when replica is deleted
        onDelete: yes
        # Whether the operator during reconcile procedure should drop replicas when replica volume is lost
        onLostVolume: yes
        # Whether the operator during reconcile procedure should drop active replicas when replica is deleted or recreated
        active: no

Now active replicas are never dropped. That solves a potential bug when replica could be dropped on a multi-volume node if newly added volume is not yet available.
