Presto is an open-source distributed SQL query engine designed for running interactive analytic queries against data sources of all sizes. Developed by Facebook, Presto can query data where it lives, including data from Hadoop, NoSQL databases, and cloud storage systems, without requiring data to be moved to a centralized system. It supports a variety of data formats and provides low-latency query performance, making it ideal for interactive analysis and business intelligence applications. Presto’s architecture allows it to scale horizontally, ensuring high performance even with large datasets.
