Google logo Google has released Supersonic, a query engine designed to work efficiently with column-oriented databases. The announcement suggests that Supersonic would be "extremely useful for creating a column oriented database back-end", and that it aims to offer "second-to-none execution times". As part of achieving that design goal, the C++ library uses many low-level, cache-aware optimisations, SIMD instructions and vectorised execution so that it can make the best use of modern pipelined CPUs, while still working as a single process.

Supersonic can perform "Operations" on columnar data such as Compute, Filter, Sort, HashJoin, and more; on views these operations can be chained together to produce a final result. Data for these operations is currently held in memory; there is no current built-in data storage format, but the developers say that there is "a strong intention of developing one". Other work in progress includes the provision of wide test coverage for the library. A tarball archive of the code is available to download, while the source can be git cloned from the Google Code project pages.
