DB2 with BLU Acceleration: So Much More than Just a Column Store

Summary: DB2 BLU accelerates BI queries with a column-store, dictionary compression, and SIMD in-memory processing, delivering 10–50× speedups and 3–10× better compression than row stores. It processes predicates, joins, and group-bys directly on compressed data using late materialization and parallelism, while enabling seamless mixing of column- and row-tables in one tablespace.
