             Summary: IGFS: Optimize file meta update operations using entry processors.
                 Key: IGNITE-2814
                 URL: https://issues.apache.org/jira/browse/IGNITE-2814
             Project: Ignite
          Issue Type: Task
          Components: IGFS
    Affects Versions: 1.5.0.final
            Reporter: Vladimir Ozerov
            Priority: Critical
             Fix For: 1.7


*Problem*
There are 3 operation types performed on files during write:
1) lock
2) unlock
3) length update

Some of there operations perform put/replace on cache to update meta. This is less than efficient because we have to pass the file {{IgfsFileInfo}} which is pretty heavy.

*Solution*
We must ensure that all these operations use light-weight entry processors instead.
