> I have replaced all my super column families with regular column families using composite columns. I have easily been able to support all previous functionality (I don't need range delete) except for one thing: getting multiple super columns with a single access. For this, I would need to get multiple ranges. (I can get multiple columns, or a single range, but not multiple ranges.) 
> For example, I used to have
> [<superColumnName1>,<subColumnName1..N>],[<superColumnName2>,<subColumnName1..N>]
> and I could get superColumnName1, superColumnName2
> Now I have
> [<len><superColumnName1>0<len><subColumnName1>..<len><superColumnName1>0<len><subColumnNameN>],[<len><superColumnName2>0<len><subColumnName1>..<len><superColumnName2>0<len><subColumnNameN>]
> and I need to get superColumnName1..superColumnName1+, superColumnName2..superColumnName2+
> to get the same functionality
> I would like the clients to support this functionality, e.g. Hector to have .setRages parallel to .setColumnNames 
> and for CQL to support a syntax like 
> SELECT [FIRST N] [REVERSED] name1..nameN1, name2..nameN2... FROM ...
