6848	An Open Source Column-Store Backend	anonymous	nobody	"Adding a [http://en.wikipedia.org/wiki/Column-oriented_DBMS column-store database] backend would, transparently, allow Django to become applicable to a wider array of problems. Column-stores are being [http://www.databasecolumn.com/ touted] by some leading pioneers in the database community as a solution to some of the prevalent problems in database management specifically exacerbated by row-based storage (i.e. MySQL, postgrs, Oracle, etc.) of large sets.

The shortcomings of column-store backend are both general and specific: 
 * Column stores are less efficient at inserts and updates due to their aggressive compression and indexing.
 * The below implementations are not in the usual palette of database solutions provided by shared web hosts, nor have most web developers paid much attention to the [http://en.wikipedia.org/wiki/Vldb VLDB] world.
 * Little legacy data is stored in databases of this type, reducing the effectiveness of inspectdb, one of the killer Django hooks."		closed	Database layer (models, ORM)	dev		wontfix	feature sql		Unreviewed	0	0	0	0	0	0
