[jira] [Created] (CASSANDRA-12605) Timestamp-order searching of
sstables does not handle non-frozen UDTs, frozen collections correctly
Tyler Hobbs created CASSANDRA-12605:
---------------------------------------
Summary: Timestamp-order searching of sstables does not handle non-frozen UDTs, frozen collections correctly
Key: CASSANDRA-12605
URL: https://issues.apache.org/jira/browse/CASSANDRA-12605
Project: Cassandra
Issue Type: Bug
Reporter: Tyler Hobbs
Assignee: Tyler Hobbs
{{SinglePartitionReadCommand.queryNeitherCountersNorCollections()}} is used to determine whether we can search sstables in timestamp order. We cannot use this optimization when there are multicell values (such as unfrozen collections or UDTs). However, this method only checks {{column.type.isCollection() || column.type.isCounter()}}. Instead, it should check {{column.type.isMulticell() || column.type.isCounter()}}.
This has two implications:
* We are using timestamp-order searching when querying non-frozen UDTs, which can lead to incorrect/stale results being returned.
* We are not taking advantage of this optimization when querying frozen collections.
