Get nodes from cluster client

[nihohit]

@danprueitt has this issue been fully or partially mitigated in 0.25.0?

Routing will be exposed in the async cluster in the next release (

redis-rs/redis/src/cluster_async/mod.rs

Line 103 in a6df6e2

pub async fn route_command(&mut self, cmd: &Cmd, routing: RoutingInfo) -> RedisResult<Value> {

). If you want to contribute exposed routing to the sync cluster, that will be very much appreciated.

As for being able to iterate over the connections of each node - I believe that will be simple in the sync cluster connection, but not so simple in the async one, due to its disjoint structure. Again, contributions will be very much appreciated.
In any case you can get info on the structure of the cluster using CLUSTER NODES/SLOTS/SHARDS.

Not exactly a solution to this, but anyway, for reference, I was able to make something work by hashtagging my keys and obtaining a RoutingInfo like so:

  let routing_info = RoutingInfo::SingleNode(SpecificNode(Route::new(
            get_slot("{my_pattern}".as_bytes()),
            ReplicaOptional,
        )));

(Imports are from the cluster_routing.rs)

And then using that with the newly exposed route_command function to call my function specifically to the correct node:

 let foo_cmd = redis::cmd("SCAN")
            .cursor_arg(0)
            .arg("MATCH")
            .arg("{my_pattern}:*")
            .arg("COUNT")
            .arg(1000)
            .to_owned();

        let my_res = my_conn.route_command(&foo_cmd, routing_info).await?;
