I'm open to alternative APIs, but that one makes sense to me and doesn't require adding extra parameters :)

[jira] Commented: (CASSANDRA-263) get_slice needs to support desc
from last column
Posted by "Jun Rao (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CASSANDRA-263?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12724762#action_12724762 ]
Jun Rao commented on CASSANDRA-263:
-----------------------------------
Is the problem that you don't know what the last column is? Normally, an application should be able to insert a fake column that's always larger than any real columns. Do you think that's good enough?

[jira] Updated: (CASSANDRA-263) get_slice needs to support desc
from last column
Posted by "Jun Rao (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CASSANDRA-263?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jun Rao updated CASSANDRA-263:
------------------------------
Attachment: issue263.patchv1
Attach a fix. If startColumn is empty and isAscending is false, assume that we scan from the largest column in descending order.
Also fix a bug in SliceFilterQuery.filterSuperColumn() that didn't handle descending order properly.

Jun Rao commented on CASSANDRA-263:
-----------------------------------
Using the column index to start with the last column group is possible and is efficient. I am just wondering if it is a good idea to give empty starting column different meanings depending on the ordering.

Jonathan Ellis commented on CASSANDRA-263:
------------------------------------------
Yes.
I was thinking that we could have the "CF" format (w/ no ":") stand for "start w/ first if asc or last if desc." Reading the last from the column index should be reasonably efficient, right?
