Alexei Scherbakov resolved IGNITE-5385. --------------------------------------- Resolution: Won't Fix Fixed as a part of exchange optimizations for 2.1.4 by [~sboikov] > Get rid of discovery custom message on exchange completion > ---------------------------------------------------------- > > Key: IGNITE-5385 > URL: https://issues.apache.org/jira/browse/IGNITE-5385 > Project: Ignite > Issue Type: Improvement > Components: cache > Affects Versions: 2.0 > Reporter: Yakov Zhdanov > Assignee: Alexei Scherbakov > Priority: Blocker > Labels: performance > Fix For: 2.3 > > > Currently if late affinity assignment is on we send full partition map as a > custom message to make sure all nodes get it. With greater number of nodes > and caches this can cause significant slowdowns. > We suggest to move sending to communication. In this case scenario with > coordinator failure requires special handling, since in this case some nodes > may receive full map, complete exchange and proceed with cache operations, > while others may not received full map yet. In this case full map should be > resend from new coordinator - it should be recalculated if none has received > one from former coordinator or should be requested from one of the lucky > receivers to get forwarded to other nodes. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
