Obscured question about data size in a Column Family

Hi there,

Quoting an information in the wiki about Cassandra limitations (
http://wiki.apache.org/cassandra/CassandraLimitations):
... So all the data from a given columnfamily/key pair had to fit in memory,
or 2GB ...

Does this mean
1. A ColumnFamily can only be 2GB of data
2. A Column (key/pair) can only be 2GB of data

Thanks for the explanation.

In <= 0.6 (but not 0.7) a row could not be larger than 2GB.

2GB is still the largest possible column value.
