Hi Mahesh,
Yes, it's a problem related to IGNITE_EXCHANGE_HISTORY_SIZE. Ignite
stored the data for the last 1000 exchanges.
It generally can be required for the case when the coordinator was
changed and new coordinator required to load last exchange history.
Exist two problems here:
1)Client nodes can't be a coordinator. So there is no reason to store
1000 entries there. Will be better to set this option to some small
value or zero for client nodes.
2)Server nodes also don't require 1000 entries. The required number of
exchange history can depend on the number of server nodes. I suggest
change the default value to small value.
Here is the ticket related to this problem:
https://issues.apache.org/jira/browse/IGNITE-11767
It fixed and should be available in Ignite 2.8 where these exchanges
will take less memory.
BR,
Andrei
