Alex Petrov commented on CASSANDRA-12694:
-----------------------------------------
bq. I want to fetch all columns but only query the one from columnsToRead()
In both cases ({{all(cfm)}} and {{all(cfm, columns)}}), the output is similar,
with several exceptions (for example, when only static columns are used in
condition or only regular columns are used: in these cases we will return only
them). I've added more tests for such behaviour.
Although after looking at it again I think that new output is better/more
correct, as we do have a partition and now the output corresponds to that fact
(in case with {{NOT EXISTS}} in tests.
You're right that it's better to avoid using {{selection}}, and example with
{{NOT EXISTS} kind of proves it. As with {{selection}} the output was as if
partition did not exist at all, but it did exist, even though all the rows were
deleted.
If you think this is ok, I'll rebase the other versions, too.
