Subject Re: when are the storm window start?
Date Thu, 06 Dec 2018 03:49:25 GMT
 My recollection is as follows:
 - the window end time is computed first and that implies the start time. - The window end
times for a event is determined based on alignment with the slide interval     I think
this is the relevant code: https://github.com/apache/storm/blob/v1.2.2/storm-core/src/jvm/org/apache/storm/windowing/WatermarkTimeTriggerPolicy.java#L110-L116

will be evaluated."
