Support KEYS command

[mpangrazzi]

Hi,

sorry if someone already asking that, but is there any plan to support KEYS command?

@xmikex83 I don't think it would be possible to implement KEYS command, unless we send the KEYS command to all the backend servers

[bitthegeek]

Same with DBSIZE commands. I've seen another Redis Cluster substitute implementing that and adds up all responses from the backend servers.

These commands would be nice additions especially monitoring or debugging with twemproxy with lots of nodes.

It would be super useful, since there are applications like Sidekiq that uses keys command.

Any updates on this? I'm really interested in this. I'm using KEYS in my app to get a list of all non expired keys with a certain pattern (<user_id>:active:*)

👍

It could be nice if it works at least when using hash_tag in pattern.
with hash_tag: "<>",
keys *<foo>* should return keys
keys *<fo*o>* should fail
keys *foo* should fail

Please add keys support!!!

Since Keys command is considered evil don't know if it is worth it to invest time on it in twemproxy.

[idning]

keys is not possible(or very difficult) in twemproxy, we will not support it.

Would you be able to recommend a substitute to get similar behavior? @idning can you continue on your comment by explaining how to inspect the keys currently in a twemproxy'd redis instance?

@dawsbot why do you need keys? keys is very dangerous command.
If you need all keys list, connect each redis server and run scan command. I think It is better.
