Subject [jira] Commented: (HBASE-1935) Scan in parallel
Date Fri, 25 Feb 2011 19:36:21 GMT

Otis Gospodnetic commented on HBASE-1935:
-----------------------------------------

I'm wondering what sort of a speed improvement one can expect from parallel scans?  I know
there is no universal answer, but if anyone has used this, I'd love to get the feeling for
this.  Thanks.

> A scanner that rather than scan in series, instead scanned multiple regions in parallell
would be more involved but could complete much faster partiularly if results are sparse.
