The maximum supported task frequency of this scheduler, i.e. the inverse of the minimum time interval between executions of a recurring task, in Hz.

Scala API: Schedules a Runnable to be run once with a delay, i.e. a time period that has to pass before the runnable is executed.

Deprecated API: See Scheduler#scheduleWithFixedDelay or Scheduler#scheduleAtFixedRate.

Java API: Schedules a message to be sent repeatedly with an initial delay and frequency. E.g. if you would like a message to be sent immediately and thereafter every 500ms you would set delay=Duration.ZERO and interval=Duration.ofMillis(500)

It will compensate the delay for a subsequent message if the sending of previous message was delayed more than specified. In such cases, the actual message interval will differ from the interval passed to the method.

If the execution is delayed longer than the interval, the subsequent message will be sent immediately after the prior one. This also has the consequence that after long garbage collection pauses or other reasons when the JVM was suspended all "missed" messages will be sent when the process wakes up again.

In the long run, the frequency of messages will be exactly the reciprocal of the specified interval.

Warning: scheduleAtFixedRate can result in bursts of scheduled messages after long garbage collection pauses, which may in worst case cause undesired load on the system. Therefore scheduleWithFixedDelay is often preferred.

Note: For scheduling within actors AbstractActorWithTimers should be preferred.

Java API: Schedules a Runnable to be run repeatedly with an initial delay and a frequency. E.g. if you would like the function to be run after 2 seconds and thereafter every 100ms you would set delay to Duration.ofSeconds(2), and interval to Duration.ofMillis(100).

It will compensate the delay for a subsequent task if the previous tasks took too long to execute. In such cases, the actual execution interval will differ from the interval passed to the method.

If the execution of the tasks takes longer than the interval, the subsequent execution will start immediately after the prior one completes (there will be no overlap of executions). This also has the consequence that after long garbage collection pauses or other reasons when the JVM was suspended all "missed" tasks will execute when the process wakes up again.

In the long run, the frequency of execution will be exactly the reciprocal of the specified interval.

Warning: scheduleAtFixedRate can result in bursts of scheduled tasks after long garbage collection pauses, which may in worst case cause undesired load on the system. Therefore scheduleWithFixedDelay is often preferred.

If the Runnable throws an exception the repeated scheduling is aborted, i.e. the function will not be invoked any more.

Java API: Schedules a message to be sent repeatedly with an initial delay and a fixed delay between messages. E.g. if you would like a message to be sent immediately and thereafter every 500ms you would set delay=Duration.ZERO and interval=Duration.ofMillis(500).

It will not compensate the delay between messages if scheduling is delayed longer than specified for some reason. The delay between sending of subsequent messages will always be (at least) the given delay.

In the long run, the frequency of messages will generally be slightly lower than the reciprocal of the specified delay.
