Allowed Pod disruptions

You can configure the permitted Pod disruptions for Kafka nodes as described in Allowed Pod disruptions.

Unless you configure something else or disable the default PodDisruptionBudgets (PDBs), the operator writes the following PDBs:

Brokers

Only a single Broker is allowed to be offline at any given time, regardless of the number of replicas or roleGroups. This is because we can not make any assumptions about topic replication factors.

KRaft controllers

Only a single Controller is allowed to be offline at any given time, regardless of the number of replicas or roleGroups. This is because they build a quorum for metadata.
