Flink: Is there a way to find the age of an element in a Global window?












0















I'm using Global Windows for my application with a custom trigger and custom evictor based on some conditions. Now, I also want to evict those elements from the window that have stayed there for too long, let's say 30 mins. How would I go about doing this? Is there a utility that Flink provides that lets me know what the age of an element in a window is?

          An Evictor is passed an EvictorContext that provides access to the current watermark and the current processing time. If you timestamp your stream elements then you should have everything you need.
