what should i do, if i want to scan somekeys in a specific node?

[NaraLuwan]

now, the scan fun only the following params are supported:
Scan(ctx context.Context, cursor uint64, match string, count int64)

Is it possible to add the node param? If not, how do we do that now?

You could use ForEachNode to iterate over all nodes and pick the one you need. But we should probably add something like cluster.ShardForKey(string) *redis.Client to get the node for the key.

but my redis has a proxy cluster, When I create the client, I call method NewClient instead of method NewClusterClient

I tried it this way, it works for me

ScanNode := func(ctx context.Context, rdb *redis.Client, cursor uint64, nodeId string) *redis.StringSliceCmd {
	cmd := redis.NewStringSliceCmd(ctx, "scan", cursor, nodeId)
	_ = rdb.Process(ctx, cmd)
	return cmd
}

res, err := ScanNode(ctx, rdb, 0, "xxx").Result()
