    Description

      There are certain class of RPCs that need priority delivery. This applies especially to heartbeat RPCs that distributed systems (like HDFS) uses. Ability to deliver heartbeat RPCs earlier than other data-movement RPCs can improve the scalability of large scale distributed systems.
