Denodo Platform vs Teiid

Denodo Platform has no write-up on Specifiction yet; its figures are above.

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.
