> Currently, all commands queued for a datanode are stored in an ArrayList, which is sent to the DN on each heartbeat.
> In order to limit the number of commands queued on a DN at any time, it would be useful to be able to query the current queued count of each command type, allowing Replication Manager, for example, to stop sending more work to the DN until it has free capacity.
