    Description

      When a coordinator fails, the group membership protocol tries to failover to a new coordinator without forcing all the consumers rejoin their groups. This is possible if the coordinator persists its state so that the state can be transferred during coordinator failover. This state consists of most of the information in GroupRegistry and ConsumerRegistry.
