DB2 11 for LUW includes a broad set of enhancements to BLU Acceleration, taking the columnar in-memory database technology to a new level of maturity, performance, and scalability. Matthias Nicola from IBM provides an overview of new features and improvements in BLU Acceleration in DB2 11.1
The DB2 BLU Engine, which introduced column-organized tables, was released with DB2 10.5 and greatly enhanced in 10.5 Fixpack 4. DB2 11.1 introduces BLU MPP – support for BLU tables within a DPF environment. This greatly increases the scalability of a BLU system.
