-----------------------------------
> 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
> Assignee: 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.
