Abstract:
The present invention generally relates to data processing, and more specifically to executing a query against a partitioned database. The query may be executed against each partition of a database to retrieve results from each partition. The results from the partitions may be integrated to provide the results of the query. Each partition may take different amounts of time to retrieve results for the query. Embodiments of the invention allow adjusting the execution of the query for faster executing partitions to allow execution of other tasks, thereby increasing query throughput.
