[jira] [Created] (ARROW-7998) [C++][Plasma] Make Seal requests synchronous

Stephanie Wang created ARROW-7998:
-------------------------------------

             Summary: [C++][Plasma] Make Seal requests synchronous
                 Key: ARROW-7998
                 URL: https://issues.apache.org/jira/browse/ARROW-7998
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++ - Plasma
    Affects Versions: 0.16.0
            Reporter: Stephanie Wang
            Assignee: Stephanie Wang
             Fix For: 0.16.1


When handling a `Seal` request to create an object and make it visible to other clients, the plasma store does not wait until the seal is complete before responding to the requesting client. This makes the interface hard to use, since the client is not guaranteed that the object is visible yet and would have to use an additional IPC round-trip to determine when the object is ready.

 

This improvement would require the plasma store to wait until the object has been created before responding to the client.
