Hi Brian, HBase doesn't support indexes on non-primary-key values or secondary/text indexes today. But should HBase support any of them in the future?
Without indexes on non-primary-key values, the query execution is scan-based. Map/Reduce will help, but the queries won't be real-time. As to secondary/text indexes, does HBase need a coupled secondary index? Or is a de-coupled, relatively independent secondary index sufficient? What are people's takes on this?
