Presto is an open source, distributed SQL engine for online analytical processing that runs in clusters. Presto can query a wide variety of data sources, from files to databases, and return results to many BI and analysis environments. What’s more, Presto allows querying data where it lives, including Hive, Cassandra, relational databases, and proprietary data stores. A single Presto query can combine data from multiple sources. Facebook uses Presto for interactive queries against several internal data stores, including their 300PB data warehouse.The Presto Foundation is the organization that oversees the development of the Presto open source project. Facebook, Uber, Twitter, and Alibaba founded the Presto Foundation. Additional members now include Alluxio, Ahana, Upsolver, and Intel.— Martin Heller
