Cluster Membership
Peer add/remove can only be performed on the leader node.
Bootstrap Baselines
— committed at first cluster formation
Emergency Recovery
— resync a diverged database from the leader
Drops this node's local copy of the selected database and re-downloads a fresh full
snapshot from the leader. Use when this follower has diverged (e.g. a
WALVersionGapException / snapshot resync required error).
Leadership
Leadership actions can only be performed on the leader node.
Move leadership to a node that holds a database the current leader is missing, then resync the
others (the #4522 recovery flow).
Database Consistency
Compares per-file checksums of each database across every node and reports any mismatch.
Danger Zone
These actions can disrupt the cluster. Use with caution.
