Hi, I scanned through HBase' Scan API and couldn't find out how to scan a range of columns in a row.
It seems I can only do scan(startRow, endRow), which are both just RowKeys. What's the most efficient way to do it? Should I use a Filter? I heard filter is not as efficient as RK scans, how much slower is it? (BTW, I was using Accumulo for the same thing and it has a really nice API (Range, Key) for it. A Key is a combination of RK+CF+CQ+TS.) Am I missing anything? Cheers, -- Jianshi Huang LinkedIn: jianshi Twitter: @jshuang Github & Blog: http://huangjs.github.com/
