[jira] [Commented] (IGNITE-11767) GridDhtPartitionsFullMessage retains huge maps on heap ion exchange history

["Pavel Kovalenko (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-11767?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16821177#comment-16821177 ] 

Pavel Kovalenko commented on IGNITE-11767:
------------------------------------------

[~ilyak] Overall approach to solving the problem looks good. Partition sizes map in FullMessage is read only once during topology update, so it's safe to keep it in the serialized format every time.

> ExchangeHistory keeps a FinishState for every topology version.
> FinishState contains msg, which contains at least two huge maps:
> partCntrs2 and partsSizesBytes.
> We should probably strip msg, removing those two data structures before putting msg in exchFuts linked list to be stowed away.
