> Key: IGNITE-6641
> URL: https://issues.apache.org/jira/browse/IGNITE-6641
> Project: Ignite
> Issue Type: Improvement
> Security Level: Public(Viewable by anyone)
> Components: cache
> Reporter: Sergey Chugunov
> Assignee: Sergey Chugunov
> Fix For: 2.4
>
>
> All in-memory caches share the same FreeList data structure which relies on
> pageId comparisons to manage its internal state.
> As described in javadoc for *FullPageId* class each pageId contains a
> partitionID part which is not guaranteed to be constant and is going to be
> changed as part of a linked ticket.
> Thus we need to exclude partitionID when using pageId for comparisons that
> expect pageId to be constant.
> h2. Notes
> This change is not applicable for persistent caches as they maintain separate
> FreeList for each partition so partitionID part is constant for pages from
> that partition.
