Redis KEYS Method

[woozyking]

Hi,

When I call redis.keys("*") method, it would give me only the keys from one node from the cluster.

So I gave the map() method a try:

with redis.map() as c:
    r = [c.keys(*)]

Which still gives me the single node's values. Maybe I just used the map() wrong. Then I tried redis methods like info() and dbsize(), they all report back a list of values representing the whole cluster.

Please let me know if it's possible to achieve this.

Thanks in advance.

There's no good way to do this at the moment. You'd have to call out to each individual connection or setup a custom router which understood the keys command and ran it on all nodes.

It's pretty awful but you can do this:

keys = []
for db in cluster:
  keys.extend(cluster[db].keys())

Thanks @dcramer, that's not so bad, given that my use case here is just to occasionally inspect the keys of all nodes.
