Abstract
Provided herein are systems and methods for a stream object configuration, including query processing of stream objects using stream expansion. For example, a method includes decoding a query to obtain a first data processing operation and a first stream object. The first stream object is associated with a view on a base table. A first stream expansion on the first stream object is performed. The first stream expansion is based on generating a second stream object on the base table. A second stream expansion of the second stream object is performed. The second stream expansion is based on replacing the second stream object with at least a second data processing operation. The query is executed based on completing the first data processing operation and the at least a second data processing operation.
