Bistro: a new approach to data processing

Bistro is a light-weight column-oriented data processing engine which changes the way data is being processed. It is based on a new data model and is an alternative to conventional SQL-like languages, map-reduce and other set-oriented approaches. Bistro can be applied to many problems like data integration, data migration, extract-transform-load (ETL), big data processing, stream analytics, big data processing, IoT analytics.
