Hello, Does Beam outline what runners should do if a user queries MetricsResult after a pipeline has been cancelled? I understand this is an experimental feature and is a work in progress, but I could not find this detail in the mailing lists, BEAM-147 [1], or the Aggregator->Metrics Doc [2]
Thanks, Paul Gerver [1] https://issues.apache.org/jira/browse/BEAM-147 [2] https://docs.google.com/document/d/1voyUIQ2DrWkoY-BsJwM8YvF4gGKB76CDG8BYL8XBc7A/edit#heading=h.vv2fbulkp7t
