thanks for sharing this proposal. How would fault tolerance work with the
BatchFunction? Since the batch function seems to manage its own buffer,
users would also have to make sure that in-flight elements which are

Could you not do the same thing today with a FlatMap function that
stores incoming elements
and only computes and collects a result when a certain threshold is reached?
