Description
CASSANDRA-11196 accidentally broke reading from tables with mixed clustering column order in the opposite direction.
ReversedPrimaryKeyRestrictions::boundsAsComposites method attempts to reverse the list returned from PrimaryKeyRestrictionSet::boundsAsComposites and fails, as Guava’s Lists::transform method returns a List that doesn’t support set().
Reproduction:
CREATE TABLE test.test (
a int,
b int,
c int,
PRIMARY KEY (a, b, c)
) WITH CLUSTERING ORDER BY (b ASC, c DESC);
SELECT * FROM test.test WHERE a = 0 AND (b, c) > (0, 0) ORDER BY b DESC, c ASC;
> ServerError: java.lang.UnsupportedOperationException
java.lang.UnsupportedOperationException: null
