Motivation and Background
At Meta (Facebook), Presto is a distributed real-time query engine using SQL language as an interface to perform fast, interactive queries on petabytes of data. It supports standard ANSI SQL, including queries, aggregations, JOINs, and window functions.
Alluxio is the data orchestration platform as a critical technology supporting Presto and various other data analytics applications and use cases. Alluxio creates a virtual data layer that federates data from any file system or object store, provides a unified namespace across storage systems, and serves the data to the applications using industry-standard interfaces with fast data access.
