BackoffRetryStrategy
open class BackoffRetryStrategy: JobRetryStrategy
Will retry the job every N seconds, scaling at a power of 2, until a max number of seconds is reached, at which point the queue will try to re-process the job at that max time interval.
MaxRetryStrategy is appropriate for situations wherein failure may decrease over time. A good example would be a Processor which is attempting to upload data to a server, but the server is down. We don’t want to continuously ping the server, rather we want to gradually back off more and more over time until the server is back online.
