how to delete these redis key?

Answer 1

As in How to atomically delete keys matching a pattern using Redis, this will work, using Lua scripting:

redis-cli EVAL "return redis.call('del', unpack(redis.call('keys', ARGV[1])))" 0 "*Likes*"

And if you have thousands of keys

EVAL "local keys = redis.call('keys', ARGV[1]) \n for i=1,#keys,5000 do \n redis.call('del', unpack(keys, i, math.min(i+4999, #keys))) \n end \n return keys" 0 "*Likes*"
