   1、master 节点写入压力非常大的情况下，发现slave 与master的连接会断开，导致全量发起同步，引起雪崩
   
   2、master在compaction的时候，会卡顿，导致客户端连接断开，引起应用重连

   > slave断开后，master写入压力大，会超出wal size，所以需要全量复制。 尝试增大rocksdb.wal_ttl_seconds 和 rocksdb.wal_size_limit_mb 32768 会解决这个问题。
   
   不是slave断开引起的全量复制， 是在写入压力大的情况下，主从复制会断开，像是master会卡住一段时间，包括业务连接和主从复制的那条链接。    
   
   主从复制的连接断开后，会触发从master 的全量复制   @twoholes @PragmaTwice
