T Jake Luciani commented on CASSANDRA-7279:
-------------------------------------------

So the issue is the ABSC is blindly adding the overlapping slices so it ends up 
with dups.  

We can  fix this by:
  - cropping the slices so none of them intersect.
  - changing ABSC.maybeAppendColumn to use addColumn vs addInternal (so it 
checks the previous value)

I prefer the first but there would be a number of places to change if we did it 
at the iterator level.  Since this is only exposed in thrift the simplest place 
would be there.
