Cassandra 0.7 Can Pack 2 Billion Columns Into a Row

angry tapir writes "The cadre of volunteer developers behind the Cassandra distributed database have released the latest version of their open source software, able to hold up to 2 billion columns per row. The newly installed Large Row Support feature of Cassandra version 0.7 allows the database to hold up to 2 billion columns per row. Previous versions had no set upper limit, though the maximum amount of material that could be held in a single row was approximately 2GB. This upper limit has been eliminated."

Cassandra appears to be a multi-dimensional datastore that does not store data in the same fashion as a typical RDBMS. It uses columns and rows both to store sets of data uniquely. If you're familiar with Big Table, then, apparently, its kinda like that.

That just means that they've added even more storage vectors to it than before...not sure why it made slashdot front page...

Not with column store databases such as Cassandra, HBase and BigTable.
