Apr 12, 2024 · How does PrestoDB work? PrestoDB is an open-source distributed SQL query engine for running interactive analytic queries against all types of data sources. It enables self-service ad-hoc analytics on large amounts of data.
Presto can query data where it is stored, without needing to move data into a separate analytics system. Query execution runs in parallel over a pure memory-based architecture, with most results returning in seconds.
The Presto Command Line Interface (CLI) is a terminal-based interactive shell for running queries, and is a self-executing JAR file that acts like a normal UNIX executable. The Presto CLI communicates with the Presto server over HTTP using a REST API, documented at Presto Client REST API.
Jul 18, 2020 · When Presto executes a query, it does so by breaking up the execution into a hierarchy of stages. Stage models a particular part of a distributed query plan. Each stage reads from data source and writes to an output buffer, and there are two types of sources:
Presto (including PrestoDB, and PrestoSQL which was re-branded to Trino) is a distributed query engine for big data using the SQL query language. Its architecture allows users to query data sources such as Hadoop, Cassandra, Kafka, AWS S3, Alluxio, MySQL, MongoDB and Teradata, [1] and allows use of multiple data sources within a query.
