Presto First Steps

enter image description here

SQL at any scale

Topic: Data
Manfred Moser

Open source distributed SQL query engine Presto allows you to efficiently query data against disparate sources of all sizes. It unlocks access to all these sources with standard SQL queries and therefore supports a large choice of established business intelligence and reporting tools. Presto can query all data sources at the same time and process queries for analytical needs with unparalleled query performance. Initially developed by Facebook, open source Presto is now used by a wide range of companies, including Netflix and Airbnb.

Join expert Manfred Moser for a hands-on introductory overview of Presto. Through concise demonstrations and interactive exercises, you’ll learn how to run a Presto cluster for production usage, how to configure catalogs to connect data sources, and how to use various tools to query data. You’ll leave with everything you need to get started with this powerful query engine.

What you'll learn-and how you can apply it

By the end of this live online course, you’ll understand:

  • The underpinnings that make Presto a scalable, high-performance query engine
  • How to connect numerous, largely different data sources
  • How to use SQL to query data in any data source directly, even simultaneously
  • How to query and visualize with tools to gain better insights
  • Resources to help you continue learning

And you’ll be able to:

  • Install and run Presto for testing and a Presto cluster for production usage
  • Configure catalogs to connect data sources
  • Run SQL queries with the Presto CLI
  • Set up other SQL tools with a JDBC connection
  • Discover what connectors are available

This training course is for you because...

  • You’re a data analyst trying to work with one or more data storage systems.
  • You work with numerous databases and need to query them at scale.
  • You don't want to use different query languages and tools for different data sources.
  • You want to become an efficient data analyst and enable other analysts.


  • A working knowledge of the command line on a Linux or macOS system
  • A basic understanding of databases and SQL
