Abstract
Disclosed herein are system, method, and computer program product embodiments for a massively parallel processing (MPP) database system. The embodiments disclosed herein more quickly retrieve results from computer nodes configured to process and store distributed datasets. An embodiment operates by utilizing a middleware adapter residing in a server to send queries to a middleware controller residing in a database cluster. The queries are parsed and delivered as sub-queries to computer nodes within the database cluster. In an embodiment, sub-queries represent a query plan for faster execution. In an embodiment, the queries are also functionally translated to provide more operators than available solely based on the database cluster context. After a computer node completes the execution of a sub-query, the result is delivered directly to the middleware adapter without the need to wait for other sub-queries to complete execution.
