What is Presto?

Presto is an open source distributed SQL query engine for running interactive analytic queries against data sources of all sizes ranging from gigabytes to petabytes.

Designed for casual style, Nike Presto shoes are built for everyday comfort. Bottle version of the best matte top coat on the market. Transforms any gel color or design to a long-lasting, matte finish. Wipe with Presto Nail Cleanser after curing to remove residue and oils. Pressure Cookers & Electric Appliances.

Presto was designed and written from the ground up for interactive analytics and approaches the speed of commercial data warehouses while scaling to the size of organizations like Facebook.

The community owned and driven Presto project is supported by the Presto Foundation, an independent nonprofit organization with open and neutral governance, hosted under the Linux Foundation®.

What can it do?

Presto allows querying data where it lives, including Hive, Cassandra, relational databases or even proprietary data stores. A single Presto query can combine data from multiple sources, allowing for analytics across your entire organization.

Presto is targeted at analysts who expect response times ranging from sub-second to minutes. Presto breaks the false choice between having fast analytics using an expensive commercial solution or using a slow 'free' solution that requires excessive hardware.

Who uses it?

Facebook uses Presto for interactive queries against several internal data stores, including their 300PB data warehouse. Over 1,000 Facebook employees use Presto daily to run more than 30,000 queries that in total scan over a petabyte each per day.

Leading internet companies including Airbnb and Dropbox are using Presto.

Presto is amazing. Lead engineer Andy Kramolisch got it into production in just a few days. It's an order of magnitude faster than Hive in most our use cases. It reads directly from HDFS, so unlike Redshift, there isn't a lot of ETL before you can use it. It just works.

We're really excited about Presto. We're planning on using it to quickly gain insight about the different ways our users use Dropbox, as well as diagnosing problems they encounter along the way. In our tests so far it's been rock solid and extremely fast when applied to some of our most important ad hoc use cases.
