Alexander Belyak created IGNITE-6962:
----------------------------------------

             Summary: Reduce ExchangeHistory memory consumption
                 Key: IGNITE-6962
                 URL: https://issues.apache.org/jira/browse/IGNITE-6962
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.1
            Reporter: Alexander Belyak


GridDhtPartitionExchangeManager$ExhcangeFutureSet store huge message GridDhtPartitionsFullMessage with IgniteDhtPartitionCountersMap2 for each cache group with two long[partCount]. If we have big grid (100+ nodes) with large amount of cacheGroups and partitions in CachePartitionFullCountersMap(long[] initialUpdCntrs; long[] updCntrs;)
<cacheGroups>*<2 arrays>*<partCount>*<sizeOflong=8> = GridDhtPartitionsFullMessage size and we store 1000 of messages in history.
To reproduce: start few cacheGroup with huge number of partitions with few caches and analyze heap dump in Eclipse MAT (for example)
