> The {{ClusterEntrypoint}} provides the executor of the common {{RpcService}} to the {{HighAvailabilityServices}} which uses the executor to run io operations. In I/O heavy cases, this can block all {{RpcService}} threads and make the {{RpcEndpoints}} running in the respective {{RpcService}} unresponsive.
> I suggest to introduce a dedicated I/O executor which is used for io heavy operations.
