A CoLocationConstraint manages the location of a set of tasks (Execution Vertices).
A Co-location group is a group of JobVertices, where the i-th subtask of one vertex has to be executed on the same TaskManager as the i-th subtask of all other JobVertices in the same group.
A queue that returns elements in LIFO order and simultaneously maintains set characteristics, i.e., elements that are already in the queue may not be added another time.
ScheduledUnit contains the information necessary to allocate a slot for the given
A queue that maintains set characteristics, i.e., elements that are already in the queue may not be added another time.
A slot sharing units defines which different task (from different job vertices) can be deployed together within a slot.
Defines the location preference constraint.
