Presto vs Teiid

Presto is an open-source distributed SQL query engine for working with large datasets across different data sources. Its ANSI SQL interface can query information where it is stored and combine data from multiple sources in one query, for both interactive and batch workloads. The project lists ad hoc queries, reporting and dashboards, and open lakehouse workloads among its uses. Documented connectors include BigQuery, Cassandra, Delta Lake, Elasticsearch, Hive, Iceberg, Kafka, MongoDB, MySQL, PostgreSQL, and Redis. Presto can be installed from a server tarball or deployed with Homebrew, Docker, or Helm. Security options include Kerberos, LDAP, password-file authentication, access controls, secure internal communication, and OAuth 2.0. Users can work through its CLI or Console, connect with DBeaver or Tableau, use Java, Python, Go, or JavaScript clients, or access the REST API. The project is free and open source, overseen by the Presto Foundation, which describes it as independent of any single company. The documentation identifies release 0.299, while the getting-started page still refers to version 0 from June 2022.

Teiid is a free, open-source data virtualization project that gives applications a uniform way to query multiple underlying sources. It works as a gateway rather than storing the data, and virtual databases can present separate sources together so applications can join or union their results. Access is available through JDBC, ODBC, OData, and REST. Built-in translators are listed for Oracle, DB2, SQL Server, MySQL, PostgreSQL, and files; custom translators can also be made. Its optimizer uses source capability information to send query work to underlying systems where possible. Documented runtimes include Spring Boot, WildFly, embedded Java, and OpenShift, with Spring Boot noted as less feature-complete than WildFly. Teiid is aimed especially at Java developers integrating enterprise data sources. Connecting to sources commonly requires third-party drivers that are not included. The FAQ cautions that big-data, LDAP-style, and primarily streaming workloads may not be a good fit. Teiid Designer is deprecated, with no further releases expected.
