[jira] [Commented] (BEAM-3471) Create a callback triggered at the end of a batch in spark runner

    [ https://issues.apache.org/jira/browse/BEAM-3471?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16323985#comment-16323985 ] 

Etienne Chauchot commented on BEAM-3471:
----------------------------------------

For the story: I detected the lack of such a feature while coding the metrics push feature (https://issues.apache.org/jira/browse/BEAM-3310) for which I needed to push at the end of the batch to get up to date metrics and not the ones of the last push (potentially _pushPeriod_ old)

> In the future we might add new features to the runners for which we might need to do some processing at the end of a batch. Currently there is not unique place (a callback) to add this processing.
