Enum Constant Summary

Enum Constants

Enum Constant	Description
IN_TRANSITION_FROM_STANDBY_TO_LEADER	This partition is in the transition process from follower to leader, but it hasn't finished doing all the status check yet; so it's still running as a follower, but it will switch to the leader role at anytime.
LEADER	This partition is the leader.
PAUSE_TRANSITION_FROM_STANDBY_TO_LEADER	This partition is paused from follower to leader transition, to avoid two leaders in the process of store migration; so it's still running as a follower and won't switch to the leader role until the end of migration.
STANDBY	This partition is a follower.
