> Key: IGNITE-5574
> URL: https://issues.apache.org/jira/browse/IGNITE-5574
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 1.9
> Reporter: Andrey Gura
> Assignee: Andrey Gura
> Fix For: 1.9
>
>
> Currently all read/write operations for cache entry value use
> 'synchronized(this)' on cache entry. This can cause very bad concurrency in
> scenarios when many threads try to read the same entry, or entry read
> operation suould wait for some long-running update (e.g. EntryProcessor in
> atomic cache is executed while entry lock is held).
