[jira] [Resolved] (CASSANDRA-11401) [Regression] Incorrect results
for clustering tuples query
[ https://issues.apache.org/jira/browse/CASSANDRA-11401?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tyler Hobbs resolved CASSANDRA-11401.
-------------------------------------
Resolution: Not A Problem
Okay, resolving as Not a Problem, then.
It's worth noting that if we supported {{OR}}, we could perform the contiguous slices you're looking for as explained in [this comment|https://issues.apache.org/jira/browse/CASSANDRA-6875?focusedCommentId=13992153&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13992153]. However, it's probably not worth introducing all of the complexities of {{OR}} just for that, at this time.
