title: How can I run fire quartz trigger in cluster on one instance only
body: <p>I have a clustered environment of Spring Boot instances. The instance is scheduled to send email once a day and I'm using Quartz Job Scheduler for that. However the email is being sent by all instances and I need it to be sent by only one instance. Is it possible to configure the Quartz Scheduler to fire a job on only one instance, I don't care which one.</p>
