Subject [jira] [Commented] (BEAM-3471) Create a callback triggered at the end of a batch in spark runner
Date Fri, 12 Jan 2018 14:26:00 GMT

    [ https://issues.apache.org/jira/browse/BEAM-3471?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16324019#comment-16324019
] 

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

Note that in the case of Spark runner, it could be {{SourceRdd.close()}} but it would be still
good to have a trans-runner callback that is the same for all the runners.

> 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.
