Load balancing in Redis cluster mode

[ChoSeoHwan]

Currently, when using redis-streams-adapter,
it appears that the load is only directed to one master node in the cluster.

If you check the code, it seems that streamName is used as a key for all requests,
and in this case, I know that it is concentrated on only one node according to the redis HashTable.

Is there a way to load balance redis when using this adapter?

At least I think I need to use different nodes for each Room/Namespace.

If there is a way to load balance, please let me know.

Hi!

You are right, there is currently no way to share the load between several primary nodes.

I am open to suggestions on this matter.

What we could do is to have N streams, and hash the namespace to select the stream to use.

This way:

• the load is divided between the namespaces (not evenly though)
• message order is still guaranteed

What do you think?
