Adar Dembo created KUDU-1973: -------------------------------- Summary: Coalesce RPCs destined for the same server Key: KUDU-1973 URL: https://issues.apache.org/jira/browse/KUDU-1973 Project: Kudu Issue Type: Sub-task Components: rpc, tserver Affects Versions: 1.4.0 Reporter: Adar Dembo
The krpc subsystem ensures that only one _connection_ exists between any pair of nodes, but it doesn't coalesce the _RPCs_ themselves. In clusters with dense nodes (especially with a lot of tablets), there's often a great number of RPCs sent between pairs of nodes. We should explore ways of coalescing those RPCs. I don't know whether that would happen within the krpc system itself (i.e. in a payload-agnostic way), or whether we'd only coalesce RPCs known to be "hot" (like UpdateConsensus). -- This message was sent by Atlassian JIRA (v6.3.15#6346)
