Cassandra reader with query implemented
URL: https://github.com/apache/beam/pull/7340#issuecomment-460193178
@srfrnk ok to make your tests in ITests. I will move them to UTests later on
when I'm ready. I did not take a precise look at the code, I just wanted to
discuss general directions. I'm ok to proceed with this PR as long as
@timrobertson100 is ok. I'll let Tim finish his review.
Regarding rewriting the Reader it is out of sope of this PR but definitely
promising ! I see that you replace the source with a Pardo, I think that it
deserves a general project discussion on whether we generalize this approach.
