Cassandra 0.7 Can Pack 2 Billion Columns Into a Row 235
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."

This is a feature in need of an application and I can see very few applications.
I think you're right, but as long as we're adding features for the sake of having features... why limit the table to two dimensions? Perhaps the next version of Cassandra can support 3D-data-cubes, with each cell specified via a (row,column,level) triplet. And the version after that will allow hypercubes of data with any number of dimensions (up to 2 billion dimensions maximum, of course).

I predict that bad things will come of this.
Not that anyone will believe me.

No no, one column for each resident, plus a column for the row header. Each row holds one item of information: Name, address, etc...
That way, adding a new data point to keep track of is a simple as inserting a new row.

How could that possibly be true, MS Access only supports 255 columns.
And now you understand why Cassandra is so important! :-)

Apparently the extra columns can be used to the effect of doing "more" than store data. A link in the article...
Not sure what that last word means....
