Cassandra reader with query implemented
URL: https://github.com/apache/beam/pull/7340#issuecomment-465958614
@srfrnk Thanks for rebasing, and also for adding your test as UTest !
Also, I just overlooked the PR (leaving the review to Tim) 2 coments:
- would it be complicated to add a more general withQuery instead of only
withWhere?
- if too complicated I would advice to update the withWhere javadoc with a
link to cassandra doc to warn the user that he should query on a
primary/clustering column and tell him about the exception he will get
otherwise.
