redis的大key如何识别？

在识别方面，Redis中的big key可以识别的程序是“redis-cli”，用户可以通过在终端中输入“redis-cli –bigkeys” 来获取Redis中的big key。当redis-cli被调用时，它将搜索所有Redis数据库中包含大量内存数据的key，并且会将其保存在本地标准输出文件中： ```java # 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). Biggest string found so far 'mykey' with 160012 bytes Biggest list found so far 'mylist' with 2304 items Biggest set found so far 'myset' with 1230 members ```
