Start scanning at the start key of the last region then you'll get that region's worth including the last row.
there is probably a better way though. We might know the last row from the HFile metadata, and one could go from there. Code would be need to be written to be efficient. It might be doable in the co-processor framework, but also possibly not without more core work. -ryan On Sat, Dec 25, 2010 at 8:55 PM, Otis Gospodnetic <[email protected]> wrote: > Hello, > > What is the quickest way (a tool) to find the last or last N row in a table? > > I'd love to be able to "tail -F a table" :) > > Thanks, > Otis > ---- > Sematext :: http://sematext.com/ :: Solr - Lucene - Nutch > Hadoop ecosystem search :: http://search-hadoop.com/ > >
