Subject [jira] [Created] (CASSANDRA-2621) sub columns under deleted CF returned
Date Sat, 07 May 2011 04:35:03 GMT
sub columns under deleted CF returned 

                 Key: CASSANDRA-2621
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 0.8.0 beta 2, 0.7.5
            Reporter: Aaron Morton
            Assignee: Aaron Morton
            Priority: Minor

found when working on CASSANDRA-2590

In some cases sub columns are not filtered to check if they have a higher timestamp than and
container super column or CF. For example a super col with two two columns, one with timestamp
0 and the other 5, will be returned with all columns even if there is a row delete at timestamp

If the QueryFilter is created with a null superColumnName in the QueryPath it will not filter
the sub columns. 

IdentityQueryFilter.filterSuperColumn() lets all sub columns through. NamesQueryFilter.filterSubColumn()
and SliceQueryFilter() check that each sub column is relavent.   

I have a fix and am working on some test cases.
