public class QueueQueryParallelizer extends SimpleParallelizer
Paralellizer specialized for managing resources for a query based on Queues. This parallelizer does not deal with increase/decrease of the parallelization of a query plan based on the current cluster state. However, the memory assignment for each operator, minor fragment and major fragment is based on the cluster state and provided queue configuration.
