Thank you. And is it similar if I want to search a subcolumn within a given supercolumn? I mean I have the supercolumn key and the subcolumn key - can I fetch the particular subcolumn?
Can you share a small piece of example code for both? I'm still new into this and trying to figure out the Thrift APIs. I attempted to use Hector, but got myself into more confusion.
