Teiid integration is available via a "Dynamic VDB" without the need for Teiid Designer tooling. While this mode of operation does not yet allow for the creation of view layers, the underlying sources can still be queried as if they are a single source. See the kit's "teiid-example/dynamicvdb-*" for working examples.
To build a dynamic VDB, you'll need to create a SOME-NAME-vdb.xml file. The XML file captures information about the VDB, the sources it integrate, and preferences for importing metadata.
VDB name pattern must adhere to "-vdb.xml" for the Teiid VDB deployer to recognize this file as a dynamic VDB.
my-vdb.xml: (The vdb-deployer.xml schema for this file is available in the schema folder under the docs with the Teiid distribution.)
