> Make page eviction start warning logged per data region instead of once per
> node
> --------------------------------------------------------------------------------

> Key: IGNITE-28099
> URL: https://issues.apache.org/jira/browse/IGNITE-28099
> Project: Ignite
> Issue Type: Task
> Reporter: Oleg Valuyskiy
> Assignee: Oleg Valuyskiy
> Priority: Minor
> Labels: ise
> Fix For: 2.19
>
> Time Spent: 20m
> Remaining Estimate: 0h

> h1. Description
> Currently the warning about page-based eviction start is logged only once per
> node, even if eviction starts in multiple data regions. The message is
> printed from {*}IgniteCacheDatabaseSharedManager#warnFirstEvict{*}:
> {code:java}
> Page-based evictions started. Consider increasing 'maxSize' on Data Region
> configuration: <region-name>{code}
> Although the log message contains the data region name, the internal flag
> *firstEvictWarn* is global for the whole
> {*}IgniteCacheDatabaseSharedManager{*}. As a result, the warning is printed
> only for the first data region where eviction starts and is suppressed for
> all subsequent regions.
> This behavior may be misleading in configurations with multiple data regions.
> If eviction starts in another region later, there will be no corresponding
> warning in the logs.
> h1. Proposed change
> Change the eviction warning logic so that the message is logged once per data
> region, instead of once per node.
> Expected behavior:
> * The warning is printed when eviction starts in a data region for the first
> time.
> * If eviction later starts in another data region, the warning is printed
> again for that region.
> * The warning should still be printed only once per region to avoid log
> flooding.
