Class RetryFilter

java.lang.Object
org.jobrunr.jobs.filters.RetryFilter
All Implemented Interfaces:
ElectStateFilter, JobFilter
public class RetryFilter extends Object implements ElectStateFilter
A JobFilter of type ElectStateFilter that will retry the job if it fails for up to 10 times with an exponential back-off policy. This JobFilter is added by default in JobRunr.

If you want to configure the amount of retries, create a new instance and pass it to the JobRunrConfiguration, e.g.: 

     JobRunr.configure()
                 ...
                 .withJobFilter(new RetryFilter(20, 4)) // this will result in 20 retries and the retries will happen after 4 seconds, 16 seconds, 64 seconds, ...
                 ...
                 .initialize();
