| <p>ElasticJob does not allow jobs to be executed at the same time. |
| When the execution time of a job exceeds its running interval, re-executing the missed task can ensure that the job continues to execute the overdue job after completing the last task.</p> |
| <h2 id="concept">Concept</h2> |
| <p>The misfire function enables the overdue tasks to be executed immediately after the completion of the previous tasks. |
| For example, if the job is executed at an hourly interval, each execution will take 30 minutes. As shown below.</p> |
| <p><img src="https://shardingsphere.apache.org/elasticjob/current/img/misfire/job.png" alt="Job"></p> |
| <p>The figure shows that the jobs are executed at 12:00, 13:00 and 14:00 respectively. The current time point shown in the figure is the job execution at 13:00.</p> |
| <p>If the job executed at 12:00 is finished at 13:10, then the job that should have been triggered by 13:00 missed the trigger time and needs to wait until the next job trigger at 14:00. As shown below.</p> |
| <p><img src="https://shardingsphere.apache.org/elasticjob/current/img/misfire/job-missed.png" alt="Job Missed"></p> |
| <p>After the misfire is enabled, ElasticJob will trigger the execution of the missed job immediately after the last job is executed. As shown below.</p> |
| <p><img src="https://shardingsphere.apache.org/elasticjob/current/img/misfire/job-misfire.png" alt="Job Misfire"></p> |
| <p>Missed jobs between 13:00 and 14:00 will be executed again.</p> |
| <h2 id="scenarios">Scenarios</h2> |
| <p>In a job scenario that takes a long time to run and has a long interval, misfire is an effective means to improve the real-time operation of the job; |
| For short-interval jobs that do not necessarily pay attention to the real-time performance of a single job, it is not necessary to turn on the misfire to re-execute.</p> |
