Well, I don't know if that's what Patrick replied but that's not correct.
The wording *is* correct, though it does uses CQL3 terms.
For CQL3, the term "partition" is used to describe all the (CQL) rows that
share the same partition key (If you don't know what the latter is:
http://cassandra.apache.org/doc/cql3/CQL.html).
So it says that all the rows sharing a particular partition key multiplied
by their number of effective columns is capped at 2 billions.
In the thrift terminology, this means a 'thrift row' (not to be confused
with a CQL3 row) cannot have more that 2 billions thrift columns'.
