Abstract
A hybrid query engine using different query engines may be implemented to provide access to a database. A database query to a database may be received at a hybrid query engine. A plan to perform the database query may be generated that when performed by the hybrid query engine causes one query engine to perform an assigned portion of the plan by accessing data that describes the database. Another portion of the plan assigned to another query engine may be performed by the hybrid query engine to cause the other query engine to perform the other portion of the plan by accessing the same data that describes the database.
