Vectorized VByte Decoding: High Performance Vector Instructions

Data-driven organizations like Indeed need great tools. We built Imhotep, our interactive data analytics platform (released last year), to manage the parallel execution of queries. To balance memory efficiency and performance in Imhotep, we developed a technique called vectorized variable-byte (VByte) decoding. VByte with differential decoding Many applications use VByte and differential encoding to compress […]
