> At least for the RSProcedureDispatcher, with CompletableFuture we do not need to set a delay and use a thread pool any more, which could reduce the resource usage and also the latency.
> Once this is done, I think we can remove the ClusterConnection completely, and start to rewrite the old sync client based on the async client, which could reduce the code base a lot for our client.
