Hi Shashika/Mohan, Just for my knowledge, Wouldn't a custom window keep a set of complete events when only a set of attributes (eg: set of 'bookID's from events) is need to be considered ? So won't this be unnecessary overhead ?
If we can create a custom function such that is keeps the BookID attributes only in an instance variable (say List), and keep doing the calculation on that List, would there be any issue with such a design ?
