Bookkeeper Sets

With a rack-aware deployment, KAAP Operator can set the data placement policy automatically. Every entry will be stored as much as possible in different failure domains to guarantee rack-level fault tolerance.

The auto-configuration of rack-awareness is enabled by default, and is configured in the Bookkeeper configuration section:

bookkeeper:
	autoRackConfig:
		enabled: true
		periodMs: 60000

The autoRackConfig feature requires bookkeeperClientRegionawarePolicyEnabled=true in the broker configuration. Fortunately, KAAP Operator will automatically add this configuration property in the broker and autorecovery values.

If you wish to disable the region-aware policy, you need to explicitly set bookkeeperClientRegionawarePolicyEnabled=false in the broker and autorecovery configuration.
