spring-scheduled

The main goal of this project is to explore basic features of the Spring build-in job scheduler.

Reference: https://spring.io/guides/gs/scheduling-tasks/

Please refer my other project concerning job scheduling: quartz.

preface

Difference between Spring build-in scheduler: comparison quartz vs spring scheduler

In short words:

• Quartz Scheduler provides support for enterprise level features like JTA and clustering. It comes with JobPersistence support that can be extremely beneficial for failed jobs as well as reporting purposes.
  Remark: In case, you need to implement the cluster across multiple machines, a time sync service daemon like http://www.boulder.nist.gov/timefreq/service/its.htm should be used to ensure that clocks are synchronized between these machines that are part of the cluster.
