Subject Recommended way to do parallel reads of a large column slice?
Date Mon, 01 Feb 2010 22:45:26 GMT

What's the recommended way to do parallel reads of a large slice of
columns when one doesn't know enough about the column names to divide
them for parallel reading in a meaningful way? SliceRange allows
setting the start and finish column names, but you wouldn't be able to
set the start field of the next read until the previous read
completed. An offset field for the SliceRange would have worked, but I
don't see it. Is there a way to divide the big read query into
multiple *parallel* small read queries without requiring advance
knowledge of the column names?
