Subject Re: 100 million columns vs 100 million rows/keys
Date Fri, 26 Nov 2010 17:04:25 GMT
Prior to Cassandra 0.7, there was a limitation of 2GB on row sizes as the
entire row had to fit in memory for compaction. As far as I'm aware, in
Cassandra 0.7, the limit has changed to 2^31 (approximately 2 billion)
columns.

See http://wiki.apache.org/cassandra/CassandraLimitations for more details.
