Subject Re: time to live rows
Date Tue, 08 Feb 2011 07:21:01 GMT
The expired columns were converted into tombstones, which will live for the
GC timeout. The "empty" row will be cleaned up when those tombstones are
removed.

Returning the empty row is unfortunate... we'd love to find a more
appropriate solution that might not involve endless scanning.
