An Open Database Connectivity (ODBC) proxy infrastructure to transparently route incoming queries to one or more selected query engines. The ODBC proxy receives a query from an application, and determines based on the characteristics of the query and the capabilities of the query engines which one or more query engines are to perform the query. The proxy then routes the query to the one or more query engines, which perform the query. The results are then returned to the proxy, which provides the results to the application.
