Subject [jira] [Updated] (BEAM-237) Should use allowedLateness from downstream computations in ReduceFnRunner
Date Thu, 28 Apr 2016 18:20:12 GMT

     [ https://issues.apache.org/jira/browse/BEAM-237?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Mark Shields updated BEAM-237:
------------------------------
    Description: 
Much of the reasoning about holds, late data and final panes in ReduceFnRunner assume the
current getAllowedLateness is an upper bound of the getAllowedLateness of all downstream computations.

There is currently no test that this is indeed the case.

It may be much simpler (for us and our users) to have a global allowed lateness setting.
