Hi!

I would like to query all the rows having a specific column defined, with Hector
For example:
- CF is a column family
- rows 1 and 3 contain columns A and B
- rows 2 and 4 contain column A only

as a result of a query "column A" I would like to get rows 1-4, with column A inside
as a result of a query "column B" I would like to get rows 1 and 3, with column A inside

How can I do that?
Is this performant?

Thanks a lot in advance

Sébastien
