The role of the watermarks in your job will be to trigger the closing of the sliding event time windows. In order to play that role properly, they should be based on the timestamps in the events, rather than some arbitrary constant (L). The reason why the same object is responsible for extracti

I should add that the behaviour persists, even when I force parallelism to 1. On Wed, Aug 21, 2019 at 5:19 PM Eric Isling wrote: > Dear list-members, > > I have a question regarding window-firing and element accumulation for a > slidindingwindow on a DataStream (Flink 1.8.1-2.12). > > My DataStr

Multiple trigger events on keyed window

2019-08-21 Thread Eric Isling
Dear list-members, I have a question regarding window-firing and element accumulation for a slidindingwindow on a DataStream (Flink 1.8.1-2.12). My DataStream is derived from a custom SourceFunction, which emits stirng-sequences of WINDOW size, in a deterministic sequence. The aim is to crete sli
