Issue
In my Redis DB I have a number of prefix:<numeric_id>
hashes.
Sometimes I want to purge them all atomically. How do I do this without using some distributed locking mechanism?
Solution
Starting with redis 2.6.0, you can run lua scripts, which execute atomically. I have never written one, but I think it would look something like this
EVAL "return redis.call('del', unpack(redis.call('keys', ARGV[1])))" 0 prefix:[YOUR_PREFIX e.g delete_me_*]
Warning: As the Redis document says, because of performance maters,
keys
command should not use for regular operations in production, this command is intended for debugging and special operations. read more
See the EVAL documentation.
