[jira] [Created] (ARROW-3958) [Plasma] Reduce number of IPCs

Philipp Moritz created ARROW-3958:

             Summary: [Plasma] Reduce number of IPCs
                 Key: ARROW-3958
                 URL: https://issues.apache.org/jira/browse/ARROW-3958
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Plasma (C++)
    Affects Versions: 0.11.1
            Reporter: Philipp Moritz
            Assignee: Philipp Moritz
             Fix For: 0.12.0

Currently we ship file descriptors of objects from the store to the client every time an object is created or gotten. There is relatively few distinct file descriptors, so caching them can get rid of one IPC in the majority of cases.
