Before implementing Function compute, is it necessary to first implement Event Streaming as a prerequisite task?

Before implementing Function compute, is it necessary to first implement Event Streaming as a prerequisite task?

IMHO, there is no conflict between the two, Event Streaming is not a pre-requisite for EventMesh Function.

@Pil0tXia Is this task to design some operators and window functions for events?

[Pil0tXia]

@jevinjiang It would require migrating the existing filter and transformer as callable functions.
