About command "keys * " in cluster--How can I get all keys in redis cluster?

How can I get all keys in redis cluster?
When I use keys * ,I get a result of the redis-server I have connected:
[admin@localhost src]$ ./redis-cli -c -p 7000
127.0.0.1:7000> keys *
(empty list or set)
127.0.0.1:7000> get foo
-> Redirected to slot [12182] located at 127.0.0.1:7002
"bar"
127.0.0.1:7002>

You can't. You would have to ask each node seperately. But please avoid KEYS * whenever possible. If you really must iterate the whole keyspace of an instance use SCAN.

Btw, this issue tracker should be used for bugs or improvements to the Redis server. For questions like your's please ask on the mailing list or in the irc channel.

Thank you for your answer.

@badboy this should be put into the documentation but thank you for the answer @mattsta

I'm not working on Redis anymore.

The docs are open at https://github.com/antirez/redis-doc, and this could belong in 'topics/cluster-tutorial.md'.

Newer versions of Redis include more cluster support in the cli. To answer the OP's question, you can do the following to have a command, such as KEYS execute on each node:

$ redis-cli --cluster call 127.0.0.1:7000 KEYS "*"

The cli also supports a --scan mode, for SCANning keys instead if using KEYS. That said, I don't think that --scan and --cluster modes play nicely together.
