[jira] [Commented] (IGNITE-9479) Spontaneous rebalance may be triggered after a cache start

    [ https://issues.apache.org/jira/browse/IGNITE-9479?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16605524#comment-16605524 ] 

Alexey Goncharuk commented on IGNITE-9479:
------------------------------------------

Also found out that we log each key during rebalancing at DEBUG level. This should be changed to TRACE.

>          Issue Type: Bug
>    Affects Versions: 2.5

> As an optimization, we do not run two-phase exchange latch release and do not validate partition counters during cache start.
> This can lead to a situation, when rebalance is mistakenly triggered under load after a cache start.
> We should treat cache start event the same way as other exchange events that need counters sync.
