Presto

Contributor(s): Matthew Haughn

Presto is a free and open source distributed SQL query engine designed for the demands of big data.

Presto can run analytic queries on data ranging from gigabytes to petabytes, which enables it to search huge data warehouses. Presto offers speeds close to those of commercial solutions without excessive hardware requirements.

Presto was purpose-designed and coded to run interactive analytical searches swiftly and process results as quickly as a commercial data warehouse. Presto can scale up to the largest requirements, dealing with the 300PB size of Facebook’s massive data warehouse while also querying multiple data sources. Presto queries data where it is resident and supports Hive, Cassandra, relational databases and proprietary data stores.

Data analysts use Presto for its fast response times, from a less than a second to minutes. Facebook uses Presto themselves: Over 1000 Facebook employees use Presto daily, to run more than 30,000 queries. On average, the queries of Facebook employees scan through over a petabyte of data every day.
