Redis has some powerful Lua scripting capabilities. One of the uses I’ve found for this feature is purging cache keys. On occasion I need to purge a set of keys that all have the same prefix.
The following command will do just that.
EVAL "return redis.call('del', unpack(redis.call('keys', ARGV)))" 0 prefix:*
prefix with whatever prefix you are looking for and they will be deleted from Redis.
