-pika的内存占用主要集中在sst文件的cache和连接申请内存，而通常连接申请内存会比sst的cache要大很多，pika目前已支持连接申请内存的动态调整、回收，因此连接占用的总内存大小是可以粗略估算的，如果你的pika内存占用远超预估或大于10g，那么可能是内存泄漏了，尝试依次执行命令`client kill all`和`tcmalloc free`来对连接内存进行强制回收，如果效果不好请升级到最新版本

 在建立主从的时候发现从库反复的进行全同步很可能是由于主库写入量太大，在全同步完毕期间清理掉了原先dumpdb时的binlog点位，导致从库在替换了db之后重新trysync发现点位又找不到，然后重新触发全同步，陷入了循环，这种场景下可以动态将主库的expire-logs-nums调大，让其保留尽量多的binlog, 建立主从成功之后再调节回来即可
