----------------------------------------
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)
