Hi,
According to the documentation ASA javascript UDAs can be used for deaccumulation. It states -The deaccumulateState() method recalculates state based on the previous state and the state of a hop. This method is called when a set of events leave a HOPPINGWINDOW. I wrote a javascript UDA in which I am trying to use the deaccumulateState method within a tumbling window query. No matter what I try, it seems that only the accumulate methods of the UDA are invoked, and the deaccumulate methods are never called. Can anyone provide some real examples of javascript UDAs that use the deaccumulateState and invoked in a query using tumbling window?
Any help on this is greatly appreciated!
A correction to my problem statement, I am using the UDA in a query with a Hopping Window, not Tumbling Window.

Hi,
Here is the URL to the documentation.
Hi Himanshu,
I was unable to use the UDA to keep state, our solution aggregates the event data using an external Azure storage table , azure functions and an event hub ASA output.
