--------------------------------------
Assignee: Ivan Bessonov (was: Kirill Tkalenko)
> B+Tree corruption during concurrent removes
> -------------------------------------------
>
> Key: IGNITE-23588
> URL: https://issues.apache.org/jira/browse/IGNITE-23588
> Project: Ignite
> Issue Type: Bug
> Reporter: Ivan Bessonov
> Assignee: Ivan Bessonov
> Priority: Critical
> Labels: ignite-3
>
> {{ItBplusTreePersistentPageMemoryTest#testMassiveRemove2_true}} fails on TC
> sometimes.
> Can be reproduced locally. In order to make it faster, data region can be
> reduced to 32Mb, number of threads to 16 and number of keys to about 8000 (I
> used {{{}threads*50{}}}).
> It's not clear how precisely it happens, but during a remove the
> {{needReplaceInner}} logic does not work as it should sometimes, leading to
> an inner node that holds an obsolete key.
> Must be fixed in both Ignite 2 and Ignite 3.
