Sylvain Lebresne commented on CASSANDRA-3791:
---------------------------------------------
Not sure I understand what you mean, it's supposed to return *all* matching
results (if the code doesn't do that, it's a bug). Taking the example in the
description, it should return 3 results, one for each value of 'c'.
To add some precision, and in case that was what you meant, the intent here is
to only support to do a IN on the last part of the PRIMARY KEY (and on the
first part since it's already supported). CASSANDRA-2710 will allow to have a
IN on other parts of the PK but that's future work.
> Support query by names for compact CF

> Current code don't allow doing a query by names on wide rows (compact CF).
> I.e. with:
> {noformat}
> CREATE TABLE test1 (
> k int,
> c int,
> v int,
> PRIMARY KEY (k, c)
> ) WITH COMPACT STORAGE;
> {noformat}
> you cannot do:
> {noformat}
> SELECT v FROM test1 WHERE k = 0 AND c IN (5, 2, 8)
> {noformat}
> even though this is a simple name query.
> This ticket proposes to allow it.
