Sun, 25 Mar 2007 19:16:49 +0000 http://www.dbms2.com/2007/03/16/data-warehouse-compression/#comment-23044 [...] I’ve recently made a lot of posts about database compression. 3X or more compression is rapidly becoming standard; 5X+ is coming soon as processor power increases; 10X or more is not unrealistic. True, this applies mainly to data warehouses, but that’s where the big database growth is happening. And new kinds of data — geospatial, telemetry, document, video, whatever — are highly compressible as well.

But once again, I don’t see why row stores can’t do that too. For example, when you join via bitmapped indices, exactly what you’re doing is operating on highly-compressed data.Want to continue getting great research about DBMS, analytics, and other technologies related to data management?
