Presto

Presto is a SQL query engine for analyzing large datasets across multiple data sources. It lets teams query data in place—without copying or moving it—so you can get results in near real time even in distributed environments.

How it works

Presto uses a federated query approach: it connects to different systems and executes standardized SQL against them. Performance depends on available server resources, and the system can be scaled to handle higher loads.

Interface and workflow

Presto is typically operated via the command line or through third-party visualization and analytics tools. To get started, you configure connections to your data sources and run SQL queries.

• Query multiple sources from one place using SQL
• Analyze data without ETL or duplication
• Use external BI systems for dashboards and visualization (no built-in charts)
• Deploy and manage it as a server/cluster setup

Deployment notes

Presto is open source, which makes it customizable and supported by community updates. Running it in production usually requires experience with server configuration and cluster management.
