用到的是redis提供--bigkeys
只能查询单个主节点，找到所有主节点依次查询即可
随便找个节点运行一下命令，如果是从节点，会告诉你去哪个主节点运行这个命令；
此处告诉我们要去172.19.161.24:6380执行（172.19.161.23:6379是172.19.161.24:6380的从节点）
[root@test ~]# redis-cli -c -h 172.19.161.23 -p 6379 --bigkeys
# Scanning the entire keyspace to find biggest keys as well as
# average sizes per key type. You can use -i 0.1 to sleep 0.1 sec
# per 100 SCAN commands (not usually needed).
TYPE returned an error: MOVED 23 172.19.161.24:6380
执行一下,看到那些事数据大的key如果大小不正常就通知存入方解决
[root@test ~]# redis-cli -c -h 172.19.161.24 -p 6380 --bigkeys
# Scanning the entire keyspace to find biggest keys as well as
# average sizes per key type. You can use -i 0.1 to sleep 0.1 sec
# per 100 SCAN commands (not usually needed).
