PrestoDB
PrestoDB is a free, open-source distributed SQL query engine for querying large datasets across different data systems.
What PrestoDB is
PrestoDB is a free, open-source distributed SQL query engine for querying large datasets across different data systems. It uses connectors through a standard API to query sources such as Hive, Iceberg, Kafka, Cassandra, MongoDB, MySQL, PostgreSQL, BigQuery, Redshift, and SQL Server. Queries are distributed across a coordinator and worker nodes. The project offers a server tarball, command line interface, JDBC driver, and Docker container, with deployment guidance for Docker, Helm, and Homebrew. It documents authentication with Kerberos, LDAP, password files, and OAuth 2.0, as well as access control and secure internal communication; SSL/TLS can protect communication between cluster nodes. Presto is self-hosted and a Linux Foundation project governed independently as open source. Its documentation cautions that it is a query engine, not a standard database with all the features that label may imply. The project directs users to its Slack community to connect with engineers and users.
Good
- Free and open source.
- Connectors cover a wide range of data systems.
- Supports Docker, Helm, and Homebrew deployment.
- Documents multiple authentication and access-control options.
- Can secure cluster communication with SSL/TLS.
Watch out
- Requires self-hosted deployment.
- It is not a standard database.
- Queries depend on supported data-source connectors.
Who it suits
PrestoDB suits teams that need to query large datasets across different systems and can manage a self-hosted deployment. It may not fit teams looking for the full feature set of a standard database.
Verdict
PrestoDB brings distributed SQL querying to data spread across heterogeneous sources, with a broad connector list and documented security controls. Check whether a query engine, rather than a standard database, suits your requirements.
