List keys

Usage: ELL *
Output is type|key|value|last_update_time|expire_time.
It shows more information than ELS.
📍Output (query) count limit: limited by redis.conf ll_max 10000.
📍Why the limit: if there are very many keys (e.g. 10 million or more) and there is no limit, other commands cannot run while this command runs, which can be a problem on production servers.
The default ll_max is 10000. You can change it at runtime with CONFIG SET if needed.
