Method Detail

schedule

public static CompletableFuture<Void> schedule(ScheduleMode scheduleMode,
                                               Iterable<ExecutionVertex> vertices,
                                               ExecutionGraph executionGraph)

scheduleLazy

public static CompletableFuture<Void> scheduleLazy(Iterable<ExecutionVertex> vertices,
                                                   ExecutionGraph executionGraph)

Schedule vertices lazy. That means only vertices satisfying its input constraint will be scheduled.

Parameters:

vertices - Topologically sorted vertices to schedule.

executionGraph - The graph the given vertices belong to.

scheduleEager

public static CompletableFuture<Void> scheduleEager(Iterable<ExecutionVertex> vertices,
                                                    ExecutionGraph executionGraph)

Schedule vertices eagerly. That means all vertices will be scheduled at once.

Parameters:

vertices - Topologically sorted vertices to schedule.

executionGraph - The graph the given vertices belong to.
