## As weighted quorums are not supported, it is imperative that an odd number of replicas
## be chosen. Moreover, the number of replicas should be either 1, 3, 5, or 7.

replicaCount: 3 # Desired quantity of ZooKeeper pods. This should always be (1,3,5, or 7)
podDisruptionBudget:
maxUnavailable: 1 # Limits how many Zokeeper pods may be unavailable due to voluntary disruptions.
terminationGracePeriodSeconds: 1800 # Duration in seconds a Zokeeper pod needs to terminate gracefully.
## OnDelete requires you to manually delete each pod when making updates.
## This approach is at the moment safer than RollingUpdate because replication
## may be incomplete when replication source pod is killed.
