Subject [jira] [Commented] (CASSANDRA-2621) sub columns under deleted CF returned
Date Wed, 01 Jun 2011 16:59:47 GMT


Jonathan Ellis commented on CASSANDRA-2621:

It sounds like the only bug here is the one described in CASSANDRA-2590, is that right?

> 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.
