Types ¶
type Store ¶
type Store struct {
// contains filtered or unexported fields
}
func (*Store) AppendCommit ¶
func (*Store) CheckpointLeadership ¶
CheckpointLeadership persists a metadata-only leader/term/epoch transition after native-raft has proven that the desired revision and nonce history are unchanged. It never writes a new desired-state commit and therefore cannot be used to bypass normal proposal sequencing.
func (*Store) Health ¶
Health verifies that the PostgreSQL connection is usable before startup reads the control-plane snapshot.
