Method Detail

releaseIn

default java.time.Duration releaseIn(Job job)

A middleware can dispose the current job or put it back to queue. While putting back, a middleware can decide to put this job in queue immediately or in 5 seconds or so. Releasing job immediately has side effect when job queue is empty. Job can reappear to the queue as soon as it is put back in the queue, so the delay should be large enough to handle parallel execution otherwise it can create loop. By default job is released to queue in one second.

Another implementation can use TaskExecutionBackOff to provide this delay

Parameters:

job - the current job

Returns:

time duration
