Abstract
A system for query planning and execution with reusable memory stack(s) is provided. In some implementations, the system performs operations comprising providing a first space in memory for storing first results of a first operator of a query, the first space located within a portion of a heap memory. The operations can further comprise generating at least a portion of the first results based on executing the first operator, providing a descriptor comprising information regarding the first space to a second operator which occurs after the first operator in a query plan, providing a second space in the previously allocated portion for storing second results of the second operator, and/or generating at least a portion of the second results based on executing the second operator using the first space. Related systems, methods, and articles of manufacture are also described.
