Class ThrottledScheduler

java.lang.Object

java.util.concurrent.AbstractExecutorService

org.mule.service.scheduler.internal.DefaultScheduler

org.mule.service.scheduler.internal.ThrottledScheduler

All Implemented Interfaces:

Executor, ExecutorService, ScheduledExecutorService, org.mule.runtime.api.scheduler.Scheduler

public class ThrottledScheduler
extends DefaultScheduler

Extension of DefaultScheduler that has a limit on the tasks that can be run at the same time.

Exceeding tasks will block the caller, until a running task is finished.

Since:

1.0

Constructor Detail

ThrottledScheduler

public ThrottledScheduler(String name,
                          ExecutorService executor,
                          int parallelTasksEstimate,
                          ScheduledExecutorService scheduledExecutor,
                          org.quartz.Scheduler quartzScheduler,
                          ThreadType threadsType,
                          ByCallerThrottlingPolicy throttingPolicy,
                          Supplier<Long> shutdownTimeoutMillis,
                          Consumer<org.mule.runtime.api.scheduler.Scheduler> shutdownCallback)

Parameters:

name - the name of this scheduler

executor - the actual executor that will run the dispatched tasks.

parallelTasksEstimate - an estimate of how many threads will be, at maximum, in the underlying executor

scheduledExecutor - the executor that will handle the delayed/periodic tasks. This will not execute the actual tasks, but will dispatch it to the executor at the appropriate time.

quartzScheduler - the quartz object that will handle tasks scheduled with cron expressions. This will not execute the actual tasks, but will dispatch it to the executor at the appropriate time.

threadsType - The ThreadType that matches with the Threads managed by this Scheduler.

throttingPolicy - the action to perform when too many tasks are running at the same time for this Scheduler.

shutdownTimeoutMillis - the time in millis to wait for the graceful stop of this scheduler

shutdownCallback - a callback to be invoked when this scheduler is stopped/shutdown.
