---------------------------------------------
Summary: Cannot perform slice reads in reverse direction against
tables with clustering columns in mixed order
Key: CASSANDRA-14899
URL: https://issues.apache.org/jira/browse/CASSANDRA-14899
Project: Cassandra
Issue Type: Bug
Components: CQL
Reporter: Aleksey Yeschenko
Assignee: Aleksey Yeschenko
Fix For: 2.2.x
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:
{code}
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
{code}
{code}
java.lang.UnsupportedOperationException: null
