Ivan Pavlukhin updated IGNITE-11289:
------------------------------------
Affects Version/s: 2.7
> BPlusTree.AbstractForwardCursor can use obsolete page
> -----------------------------------------------------
>
> Key: IGNITE-11289
> URL: https://issues.apache.org/jira/browse/IGNITE-11289
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 2.7
> Reporter: Ivan Pavlukhin
> Priority: Major
>
> There is a possibility that {{AbstractForwardCursor.nextPageId}} refers to a
> page which was already excluded from the tree. The problem reproduces with a
> scan query execution with put/remove load in background.
> Linked PR contains a reproducer and some tricks allowing to reproduce the
> problem more often (it is still possible to reproduce it without tricks but
> likelihood is significantly lower). The problem becomes evident when a
> problematic page is taken from REUSE_BUCKET. But there could be other hidden
> problems which do not cause any runtime errors but lead to data inconsistency.
