Thomas Groh created BEAM-723:
--------------------------------

             Summary: Provide a runner-internal ExecutorService for maintenance tasks
                 Key: BEAM-723
                 URL: https://issues.apache.org/jira/browse/BEAM-723
             Project: Beam
          Issue Type: Improvement
          Components: runner-direct
            Reporter: Thomas Groh
            Assignee: Davor Bonaci
            Priority: Minor


There are multiple locations throughout the DirectRunner that require some work to be done
at some later point (e.g. DirectMetrics.COUNTER_COMMITTER, EvaluationContext.watermarkCallbackExecutor).
These should use a common ExecutorService to ensure that if necessary we can manage the shared
JVM resources properly.
