Subject Re: timed-out retrieving a giant row.
Date Tue, 14 Feb 2012 20:21:54 GMT
I'm familiar to this in PHPCassa, but with Hector it would be something
like this:

Query you CF with a range.setStart(lastColName) and
range.setFinish(StringUtils.byte("") where the " lastColName " is the name
of the column from the previous read.

You can continue this until you run out of results.
