The main idea is how to allow a master to load replication info from RDB file when rebooting, if master can load replication info it means that replicas may have the chance to psync with master, it can save much traffic. The key point is we need guarantee safety and consistency, so there are two differences between master and replica: 1. master would load the replication info as secondary ID and offset, in case other masters have the same replid. 2. when master loading RDB, it would propagate expired keys as DEL command to replication backlog, then replica can receive these commands to delete stale keys. p.s. the expired keys when RDB loading is useful for users, so we show it as `rdb_last_load_keys_expired` and `rdb_last_load_keys_loaded` in info persistence. Moreover, after load replication info, master should update `no_replica_time` in case loading RDB cost too long time. |
