[jira] [Created] (BEAM-2501) Count should return a more specific type than PTransform

Thomas Groh created BEAM-2501:
---------------------------------

             Summary: Count should return a more specific type than PTransform
                 Key: BEAM-2501
                 URL: https://issues.apache.org/jira/browse/BEAM-2501
             Project: Beam
          Issue Type: Improvement
          Components: sdk-java-core
            Reporter: Thomas Groh


As {{Count.globally()}} and other static factory methods return objects of type {{PTransform}}, there is no way to communicate to the underlying {{Combine}} that we wish to have no default values, or to read the count as a {{SingletonView}} via the combiner.
