Sometimes it is needed to store compressed data in the DB. Unfortunately not all the DBs have built-in compression and FUSE compressed FSes are not available for every OS. So it may make sense to store compressed binary blobs in the DB.

	if leader && s.raft.State() != raft.Leader {
		return nil, ErrNotLeader
