Subject [jira] [Created] (BEAM-2975) Results of ReadableState.read() should be snapshots of the underlying state
Date Wed, 20 Sep 2017 23:41:00 GMT
Daniel Mills created BEAM-2975:
----------------------------------

             Summary: Results of ReadableState.read() should be snapshots of the underlying
state
                 Key: BEAM-2975
                 URL: https://issues.apache.org/jira/browse/BEAM-2975
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-core
            Reporter: Daniel Mills
            Assignee: Daniel Mills
            Priority: Minor


Future modification of state should not be reflected in previous calls to read().  For example:

@StateId("tag") BagState<Integer> state;
Iterable<Integer> ints = state.read();
state.add(17);
// ints should still be empty here.
