The default configuration is as follows:

The above configuration items is the same in *Master Server* and *Api Server*, but their *Quartz Scheduler* threadpool configuration is different.
The default quartz threadpool configuration in *Master Server* is as follows:
| Parameters | Default value |
|-------------------------------------------------------------------|-----------------------------------|
| spring.quartz.properties.org.quartz.threadPool.makeThreadsDaemons | true |
| spring.quartz.properties.org.quartz.threadPool.threadCount | 25 |
| spring.quartz.properties.org.quartz.threadPool.threadPriority | 5 |
| spring.quartz.properties.org.quartz.threadPool.class | org.quartz.simpl.SimpleThreadPool |
Since *Api Server* will not start *Quartz Scheduler* instance, as a client only, therefore it's threadpool is configured as `QuartzZeroSizeThreadPool` which has zero thread;
The default configuration is as follows:
| Parameters | Default value |
|------------------------------------------------------|-----------------------------------------------------------------------|
| spring.quartz.properties.org.quartz.threadPool.class | org.apache.dolphinscheduler.scheduler.quartz.QuartzZeroSizeThreadPool |

上述配置项在*Master Server* 和 *Api Server*是相同的，但他们的Quartz线程池配置部分却是不一样的。
*Master Server* 的Quartz线程池默认配置如下：
| Parameters | Default value |
|-------------------------------------------------------------------|-----------------------------------|
| spring.quartz.properties.org.quartz.threadPool.makeThreadsDaemons | true |
| spring.quartz.properties.org.quartz.threadPool.threadCount | 25 |
| spring.quartz.properties.org.quartz.threadPool.threadPriority | 5 |
| spring.quartz.properties.org.quartz.threadPool.class | org.quartz.simpl.SimpleThreadPool |
因为*Api Server*不会启动*Quartz Scheduler*实例，只会作为Scheduler客户端使用，因此它的Quartz线程池将会使用`QuartzZeroSizeThreadPool`。`QuartzZeroSizeThreadPool`不会启动任何线程。具体的默认配置如下：
| Parameters | Default value |
|------------------------------------------------------|-----------------------------------------------------------------------|
| spring.quartz.properties.org.quartz.threadPool.class | org.apache.dolphinscheduler.scheduler.quartz.QuartzZeroSizeThreadPool |
