Unfortunately, txredisapi doesn't work well with Redis Cluster yet. Pull Requests are welcomed :)

MOVED mean redirect to ip port then repeat command how to do it ?

IlyaSkriblovsky commented 6 years ago

I'm personally have no experience with Redis Cluster yet (i'm only using Sentinel for failover for now). So I don't have the full picture of how Redis Cluster actually works.

You may try to implement something like we did in TxMongo: https://github.com/twisted/txmongo/blob/master/txmongo/connection.py#L174 See retryNextHost. It replaces host and port attributes of self.connector to make it reconnect to different address.

Unfortunately, I have no time right now to dive into Redis Cluster and investigate it myself :(

can i fix ???

IlyaSkriblovsky commented 6 years ago

Sure, that would be great. You can clone this repository and try to fix it yourself.
