----------------------------------------------------------------------

I have few questions according to this task:

1). What is start_key in IndexClause and how should I set it here? (i read http://wiki.apache.org/cassandra/API and did not get it...)
2). I need to pass SlicePredicate into get_indexed_slices call, so the question is how to determine which columns should I include in it? should I include only columns from conditions? 

I see that in executeList() was used the following technique for SlicePredicate:

{code}
 // read all columns and superColumns
 SlicePredicate predicate = new SlicePredicate();
 SliceRange sliceRange = new SliceRange();
 sliceRange.setStart(new byte[0]).setFinish(new byte[0]);
 predicate.setSlice_range(sliceRange);
{code}

Just want to make sure I understand everything correctly here... Thanks!
