What is the default scheduler pool size in spring-boot?

Question

I\'m using spring-boot and @Scheduled annotation to execute some tasks.

How can I find out what the default pool size of scheduled tasks is

Answer 1

The default pool size is 1, and you can set the pool size in application.properties science springboot2.1.0 via changing the value of spring.task.scheduling.pool.size.

spring.task.scheduling.pool.size=20

The same task will be executed in serialized when the trigger period is shorter than the execution duration. And Spring Boot will execute different tasks in parallel with a maximum of 20 threads.
