Re: Interpretation of Trigger and Eviction on a window

Yes, that is correct. The first element will be lost. In fact, you do neither need a trigger nor an evictor if you want to get the max element for each group of 5 elements. See my reply on your other mail. Cheers, Fabian 2015-11-30 18:47 GMT+01:00 Nirmalya Sengupta : > Hello Aljoscha , > > Many

Re: Interpretation of Trigger and Eviction on a window

Hello Aljoscha , Many thanks for taking time to explain the behaviour of Evictor. The essence of my original post - about how the guide explains an Evictor - was this. I think the guide should make this (counterintuitive) explanation of the parameter to Evictor clearer. May help others, yet uninit

Re: Interpretation of Trigger and Eviction on a window

Hi Nirmalya, it is correct that the evictor is called BEFORE the window function is applied because this is required to support certain types of sliding windows. If you want to remove all elements from the window after the window function was applied, you need a trigger that purges the window. The
