> Key: IGNITE-2234
> URL: https://issues.apache.org/jira/browse/IGNITE-2234
> Project: Ignite
> Issue Type: Sub-task
> Components: general
> Affects Versions: ignite-1.4
> Reporter: Vladimir Ozerov
> Assignee: Yakov Zhdanov
> Labels: performance
> Fix For: 1.6
>
>
> GridCacheMvccManager.contextReset() method operates on a thread-local
> LinkedList. Only two operations are used: "add" and "getLast".
> Once cache op is finished, it is reset - new LinkedList is created.
> Proposed solution:
> 1) Use TLS (array + index) instead of LinkedList;
> 2) Reset = (set index to 0) + (nullify all previous elements). The latter is
> needed because GridCacheMvccCandidate migth contain references to cache
> entries.
