             Summary: The DirectRunner slows down significantly as the number of keys increases
                 Key: BEAM-839
                 URL: https://issues.apache.org/jira/browse/BEAM-839
             Project: Beam
          Issue Type: Bug
            Reporter: Thomas Groh
            Assignee: Thomas Groh


For example, running WordCount on KingLear takes approximately 10 seconds, while running WordCount on all of Shakespeare takes approximately 5 minutes. Most of this time is spent with the transforms unable to make progress, as the time is spent updating the minimum hold.
