The section on Rows vs. Columns at http://hbase.apache.org/book/schema.smackdown.html talks about expanding horizontally vs. vertically.
Can someone please explain to me when to choose rows vs. columns. The sections reads, "To be clear, this guideline is in the context is in extremely wide cases, not in the standard use-case where one needs to store a few dozen or hundred columns" so if I had 5 column families with 10 qualifiers each, accessed mostly together is this a case for wider or taller table? Thanks for any help in advance.
