[jira] [Created] (IGNITE-5574) Try to get rid of blocking synchronization on cache entry for cache.localPeek operation

-----------------------------------

             Summary: Try to get rid of blocking synchronization on cache entry for cache.localPeek operation
                 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


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).
