[jira] [Created] (BEAM-460) Implement support for size-estimation aggregators

Charles Chen created BEAM-460:

             Summary: Implement support for size-estimation aggregators
                 Key: BEAM-460
                 URL: https://issues.apache.org/jira/browse/BEAM-460
             Project: Beam
          Issue Type: Bug
            Reporter: Charles Chen
            Assignee: Charles Chen


Size-estimation aggregators are provided by the execution of each step in a Beam pipeline and help clarify the amount of data processed by each pipeline step.  To ease implementation of this feature for runners, we should first expose size-estimation support for Coder objects.  Runners can then use this functionality to implement full support for size-estimation aggregators.
