             Summary: IGFS: Optimize properties handling.
                 Key: IGNITE-2811
                 URL: https://issues.apache.org/jira/browse/IGNITE-2811
             Project: Ignite
          Issue Type: Task
          Components: IGFS
    Affects Versions: 1.5.0.final
            Reporter: Vladimir Ozerov
             Fix For: 1.7


*Problem*
We have properties map which constantly duplicated over and over again inside all {{IgfsFileInfo}} and {{IgfsListingEntry}}. This leads to substantial network traffic and most of the time these properties are a kind of defaults.

*Porposed solution*
1) If properties are deafult, do not pass them directly, but pass a special marker (e.g. boolean flag).
2) If well-known key is set (there ~3 such keys) pass only values without keys.
3) Investigate whether we need to store properties on {{IgfsListingEntry}} level.
