Philipp Moritz created ARROW-4217:
-------------------------------------

             Summary: [Plasma] Remove custom object metadata
                 Key: ARROW-4217
                 URL: https://issues.apache.org/jira/browse/ARROW-4217
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Plasma (C++)
    Affects Versions: 0.11.1
            Reporter: Philipp Moritz
            Assignee: Philipp Moritz
             Fix For: 0.13.0


Currently, Plasma supports custom metadata for objects. This doesn't seem to be used at the moment, and it will simplify the interface and implementation to remove it. Removing the custom metadata will also make eviction to other blob stores easier (most other stores don't support custom metadata).

My personal use case was to store arrow schemata in there, but they are now stored as part of the object itself.

If nobody else is using this, I'd suggest removing it. If people really want metadata, they could always store it as a separate object if desired.
