Subject Re: row key as long type
Date Thu, 08 Sep 2011 13:23:21 GMT
Row key can certainly be of type long..you'd just have to set
key_validataion_class to be LongType.

However, doing list on column family would throw an error..please look at
http://wiki.apache.org/cassandra/FAQ#a_long_is_exactly_8_bytes
