Assume you have a column family named "testCF" with comparator CompositeType(AsciiType, IntegerType(reversed=true), IntegerType); and a few columns have been inserted into record key "a".

Composite start = new Composite() ;
Composite end = new Composite() ;
start.addComponent("abc", StringSerializer.get()) ;
end.addComponent("abc", StringSerializer.get(), "UTF8Type", AbstractComposite.ComponentEquality.GREATER_THAN_EQUAL) ;

SliceQuery<String, ByteBuffer, ByteBuffer> query = HFactory.createSliceQuery(keyspace, StringSerializer.get(), ByteBufferSerializer.get(), ByteBufferSerializer.get());
query.setRange(start.serialize(), end.serialize(), false, 100);

List<HColumn<ByteBuffer, ByteBuffer>> columns = query.execute().get().getColumns();

It seems to me that your column name consists of two components. If you have the luxury to upgrade your cassandra to 0.8.1+, I think you can think about using the composite type/column. Conceptually, it might suit your use case better.

I wonder if I can select a column or all columns that start with X.
E.g I have columns ABC_1, ABC_2, ZZZ_1 and I want to select all columns that start with ABC_ - is that possible?
