DB2 with BLU Acceleration: So Much More than Just a Column Store
Raman et. al., VLDB 2013
The big idea: IBM’s venerable DB2 technology was based on traditional row-based technology. By moving to a columnar execution engine, and crucially then by taking full advantage of the optimisations that columnar formats allow, the ‘BLU Acceleration’ project was able to improve read-mostly BI workloads by a 10 to 50 times speed-up.
