-----------------------------------------
Labels: ignite-3 (was: )
> Memory leak in BaseQueryContext
> -------------------------------
>
> Key: IGNITE-16161
> URL: https://issues.apache.org/jira/browse/IGNITE-16161
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 3.0.0-alpha3
> Reporter: Vyacheslav Koptilin
> Priority: Critical
> Labels: ignite-3
> Attachments: image-2021-12-20-14-37-02-163.png

>
> BaseQueryContext contains a number of static fields that are used in order to
> store references to internal classes. For example, BaseQueryContext.CLUSTER
> which indirectly refers to ignite tables (TableImpl instances).
> Unfortunately, these references are not cleared even though the corresponding
> ignite node is stopped.
> The following trace based on a heap dump illustrates the issue:
> !image-2021-12-20-14-37-02-163.png!
> This issue can be partially mitigated by clearing ring buffers in
> StripedDisruptor, but the right way to fix the issue is a proper approach to
> handle static collections in BaseQueryContext.
