Subject [jira] [Created] (IGNITE-10920) Optimize HistoryAffinityAssignment heap usage.
Date Mon, 14 Jan 2019 09:11:00 GMT
Alexei Scherbakov created IGNITE-10920:

             Summary: Optimize HistoryAffinityAssignment heap usage.
                 Key: IGNITE-10920
                 URL: https://issues.apache.org/jira/browse/IGNITE-10920
             Project: Ignite
          Issue Type: Improvement
            Reporter: Alexei Scherbakov

With large topology and large amount of caches/partitions many server discovery events may
quickly produce large affinity history, eating gigabytes of heap.

Solution: implement some kind of a compression for affinity cache map.

On example, affinity history could be stored as delta to some previous version.
