In their own words
PrestoDB
PrestoDB is a free, open-source distributed SQL query engine for querying large data sets across different kinds of data systems. Connectors access sources through a standard API, with documented options including Hive, Iceberg, Kafka, Cassandra, MongoDB, MySQL, PostgreSQL, BigQuery, Redshift, and SQL Server. Queries run across a coordinator and worker nodes. The project provides a server tarball, command line interface, JDBC driver, and Docker container, with deployment guidance for Docker, Helm, and Homebrew. Presto documents Kerberos, LDAP, password-file, and OAuth 2.0 authentication, plus access control and secure internal communication; SSL/TLS can protect communication between cluster nodes. It is self-hosted and governed as an independent open-source project under the Linux Foundation. The documentation cautions that SQL familiarity does not mean Presto includes the features of a standard database. The project directs users to its Slack community to connect with engineers and other users. The listed current release is version 0.299, dated August 31, 2026.
