Tyler Hobbs commented on CASSANDRA-4936: ---------------------------------------- I agree with all of your points. The one thing I might change are the function names {{startOf()}} and {{endOf()}}. Since these functions are dealing with dates and times, I think the names suggest they might be altering the time component. Perhaps {{minTimeUUID()}} and {{maxTimeUUID()}}? Regarding backwards compatibility: are we carefully tracking changes to CQL by version and documenting them somewhere? These kinds of changes need to be easily discoverable, even if they are only considered bugfixes. > Less than operator when comparing timeuuids behaves as less than equal. > ----------------------------------------------------------------------- > > Key: CASSANDRA-4936 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4936 > Project: Cassandra > Issue Type: Bug > Components: Core > Affects Versions: 0.8.0 > Environment: Linux CentOS. > Linux localhost.localdomain 2.6.18-308.16.1.el5 #1 SMP Tue Oct 2 22:01:37 EDT > 2012 i686 i686 i386 GNU/Linux > Reporter: Cesar Lopez-Nataren > Assignee: Sylvain Lebresne > Fix For: 1.2.1 > > Attachments: 4936.txt > > > If we define the following column family using CQL3: > CREATE TABLE useractivity ( > user_id int, > activity_id 'TimeUUIDType', > data text, > PRIMARY KEY (user_id, activity_id) > ); > Add some values to it. > And then query it like: > SELECT * FROM useractivity WHERE user_id = '3' AND activity_id < '2012-11-07 > 18:18:22-0800' ORDER BY activity_id DESC LIMIT 1; > the record with timeuuid '2012-11-07 18:18:22-0800' returns in the results. > According to the documentation, on CQL3 the '<' and '>' operators are strict, > meaning not inclusive, so this seems to be a bug. -- This message is automatically generated by JIRA.
