Does trigger API in quartz clustered scheduler triggers job in the same local machine or any machine in the cluster?

Question

当我在集群设置中的Quartz中触发作业时，是否仅在同一台计算机上或集群设置中的任何计算机上触发该作业？

Answer 1

Quartz documentation on Clustering says (emphasis mine):

Only one node will fire the job for each firing. For example, if the job has a repeating trigger that tells it to fire every 10 seconds, then at 12:00:00 exactly one node will run the job, and at 12:00:10 exactly one node will run the job, etc. It won't necessarily be the same node each time - it will more or less be random which node runs it . The load balancing mechanism is near-random for busy schedulers (lots of triggers) but favors the same node that just was just active for non-busy (eg one or two triggers) schedulers.

Basically, once a job is scheduled to run, this information is written to the database. Any node from the cluster can read from this database and run the job.
