示例1: raftTruncatedStateLocked
// raftTruncatedStateLocked returns metadata about the log that preceded the
// first current entry. This includes both entries that have been compacted away
// and the dummy entries that make up the starting point of an empty log.
// raftTruncatedStateLocked requires that the replica lock be held.
func (r *Replica) raftTruncatedStateLocked() (roachpb.RaftTruncatedState, error) {
if r.mu.truncatedState != nil {
return *r.mu.truncatedState, nil
}
ts := roachpb.RaftTruncatedState{}
ok, err := engine.MVCCGetProto(r.store.Engine(), keys.RaftTruncatedStateKey(r.RangeID),
roachpb.ZeroTimestamp, true, nil, &ts)
if err != nil {
return ts, err
}
if !ok {
if r.isInitializedLocked() {
// If we created this range, set the initial log index/term.
ts.Index = raftInitialLogIndex
ts.Term = raftInitialLogTerm
} else {
// This is a new range we are receiving from another node. Start
// from zero so we will receive a snapshot.
ts.Index = 0
ts.Term = 0
}
