Hi,
I guess Shashika needs to read all the events in a single stream and out
put a *single value.*
*Stream1 *
Event 1 >>>>> {BookID:'001'} {BookName:'aaa' }
Event 2 >>>>> {BookID:'002'} {BookName:'bbb' }
Event 3 >>>>> {BookID:'003'} {BookName:'ccc' }
*Eg: Output the Book Count *
As per my understanding we cannot use a custom function for this use case
since it will output a result for each event.
