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 at java.util.AbstractList.set(AbstractList.java:132) ~[na:1.8.0_181] at java.util.Collections.swap(Collections.java:497) ~[na:1.8.0_181] at java.util.Collections.reverse(Collections.java:378) ~[na:1.8.0_181] at org.apache.cassandra.cql3.restrictions.ReversedPrimaryKeyRestrictions.boundsAsComposites(ReversedPrimaryKeyRestrictions.java:63) ~[main/:na] at org.apache.cassandra.cql3.restrictions.StatementRestrictions.getClusteringColumnsBoundsAsComposites(StatementRestrictions.java:580) ~[main/:na] at org.apache.cassandra.cql3.statements.SelectStatement.makeFilter(SelectStatement.java:418) ~[main/:na] at org.apache.cassandra.cql3.statements.SelectStatement.getSliceCommands(SelectStatement.java:359) ~[main/:na] at org.apache.cassandra.cql3.statements.SelectStatement.getPageableCommand(SelectStatement.java:191) ~[main/:na] at org.apache.cassandra.cql3.statements.SelectStatement.execute(SelectStatement.java:172) ~[main/:na] {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
