Jonathan Ellis commented on CASSANDRA-8692: ------------------------------------------- So with token-aware routing, the coordinator is always a replica and you get improved coalescing in the non-vnode cluster. We might be able to mitigate that at the network layer but I'm pretty sure we shouldn't try to "improve" this by redistributing vnodes; "I share data with most of the cluster" is exactly the design goal. That said, perhaps CASSANDRA-7032 would let us get by with a smaller number of default vnodes. > Coalesce intra-cluster network messages > --------------------------------------- > > Key: CASSANDRA-8692 > URL: https://issues.apache.org/jira/browse/CASSANDRA-8692 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Ariel Weisberg > Assignee: Ariel Weisberg > Fix For: 2.1.4 > > Attachments: batching-benchmark.png > > > While researching CASSANDRA-8457 we found that it is effective and can be > done without introducing additional latency at low concurrency/throughput. > The patch from that was used and found to be useful in a real life scenario > so I propose we implement this in 2.1 in addition to 3.0. > The change set is a single file and is small enough to be reviewable. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
