Re: IGNITE_EXCHANGE_HISTORY_SIZE value for Ignite client

[Denis Mekhanikov <dm...@gmail.com>]

Cristian,

I don't see any critical consequences, if you set
IGNITE_EXCHANGE_HISTORY_SIZE to 0 on clients.
Exchange futures just will be removed after each exchange. By default they
are removed only once in a while.
Don't do it on server nodes though. Coordinator needs exchange history.

Your problem sounds similar to the following issues: IGNITE-7918
<https://issues.apache.org/jira/browse/IGNITE-7918>, IGNITE-7319
<https://issues.apache.org/jira/browse/IGNITE-7319>.
Try updating to one of the nightly builds:
https://ignite.apache.org/download.cgi#nightly-builds
Or you can wait for Ignite 2.7. Its release date is right around the corner.

Denis

Thank you very much for the answer.
We will test version 2.7 once it will be released.
