Summary: Optimize RendezvousAffinityFunction Key: IGNITE-3905 URL: https://issues.apache.org/jira/browse/IGNITE-3905 Project: Ignite Issue Type: Bug Components: cache, community, general Affects Versions: 1.6 Reporter: Alexei Scherbakov Priority: Critical Fix For: 1.8 Currently RendezvousAffinityFunction.assignPartition generates a lot of garbage if called very often, on example in case of rebalancing a lot of caches. This causes excessive pressure on GC, which is not always fast enough to clear memory, producing long GC pauses leading to node segmentation. We should cache calculation of nodeHashBytes in node attribute or resort to more efficient node hash calculation. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
