Kenneth Knowles resolved BEAM-34. --------------------------------- Resolution: Fixed > Change default output timestamp for combined values to end of window > -------------------------------------------------------------------- > > Key: BEAM-34 > URL: https://issues.apache.org/jira/browse/BEAM-34 > Project: Beam > Issue Type: New Feature > Components: beam-model > Reporter: Kenneth Knowles > Assignee: Kenneth Knowles > Labels: Windowing > > Today, the output timestamp for a combined value (including iterables output > by GroupByKey) is the earliest non-late timestamp of any element combined > together. The user can customize this by specifying an OutputTimeFn, for > example choosing the latest non-late timestamp, or the end of the window. > In many respects, the end of the window is the best behaved as a default, and > is very easy to make performant. We have deferred making this change for > backwards compatibility; this is a good time to do so. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
