Abstract
A database execution engine generates a first query execution plan in response to receiving a first query, where a thread limit is specified for worker threads launched by the database execution engine. A first main executor thread is launched to process the first query and a first plurality of tasks are created to be performed in response to the first query. Then, a first plurality of worker threads are launched to perform the first plurality of tasks, where the first plurality of worker threads is less than or equal to the thread limit. In response to parallelizing processing of the first query execution plan, the first main executor thread is restricted to a first period of execution time before entering a waiting phase. The first main executor thread is woken up after the first plurality of worker threads have completed the first plurality of tasks.
