IBM speeds up DB2 10.5, remolds it as a Hadoop killer |
June 14, 2013
In the new update of DB2, released Friday, IBM has added a set of acceleration technologies, collectively code-named BLU, that promise to make the venerable database management system (DBMS) better suited for running large in-memory data analysis jobs. "BLU has significant benefits for the analytic and reporting workloads," said Tim Vincent, IBM's vice president and chief technology officer for information management software.
Developed by the IBM Research and Development Labs, BLU (a development code name that stood for Big data, Lightening fast, Ultra easy) is a bundle of novel techniques for columnar processing, data deduplication, parallel vector processing and data compression.
The focus of BLU was to enable databases to be "memory optimized," Vincent said. "It will run in memory, but you don't have to put everything in memory." The BLU technology can also eliminate the need for a lot of hand-tuning of SQL queries to boost performance.
Faster data analysis
Because of BLU, DB2 10.5 could speed data analysis by 25 times or more, IBM claimed. This improvement could eliminate the need to purchase a separate in-memory database—such as Oracle's TimesTen—for speedy data analysis and transaction processing jobs. "We're not forcing you from a cost model perspective to size your database so everything fits in memory," Vincent said.
