Garlic: A New Flavor of Federated Query Processing for DB2

Summary: Garlic is a federated query processor for DB2 enabling access to non-relational sources beside relational data. It uses DB2 catalogs as an extensible metadata store, coordinates source-specific planning with a federated server, and extends the engine to execute remote queries.
