Subject Re: Cassandra remove column using thrift
Date Fri, 01 Nov 2013 21:00:25 GMT

False alarm, sorry about that. Our column-names are byte-concatenations of
short integers and we had been constructing the column names wrongly before
attempting a delete. We fixed the problem and we've been able to delete the
columns without issue.
