------------------------------------
Summary: Try to get rid of blocking synchronization on cache entry
for cache.get operation
Key: IGNITE-4932
URL: https://issues.apache.org/jira/browse/IGNITE-4932
Project: Ignite
Issue Type: Task
Components: cache
Reporter: Semen Boikov
Assignee: Semen Boikov
Fix For: 2.1
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).
