[nguyentritai2906]

Description

This PR is from robinhood/faust adds a new function stream.take_events() which will return events()

[wbarnha]

Nice catch, this should hopefully close a lot of ongoing bugs.

[wbarnha]

Looks like the code needs to be linted.

[wbarnha]

Doesn't break any features and adds functionality, so I consider this a definite approve. LGTM.
