Study Notes
- Task scheduling is the process of automatically completing specific tasks at scheduled times.
- Distributed scheduling is needed for high availability and to prevent duplicate execution of tasks.
- In single-machine scheduling, if there is an error in the program or system, the function becomes unavailable.
- In multi-machine scheduling, without proper control, multiple tasks can start at the same time leading to confusion and errors.
- Single-machine processing has limitations in handling large volumes of data or tasks.
- Spring provides the @Scheduled annotation to implement scheduling.
- To use @Scheduled, the annotation must be added to the method in the business class, and the @EnableScheduling annotation to the start-up class.
- Distributed scheduling is necessary for high availability, prevention of duplicate execution, and handling large volumes of data or tasks.
- Distributed scheduling can be achieved through various tools and frameworks.
- Some popular distributed scheduling tools are Apache Zookeeper, Quartz, and Spring Cloud Data Flow.
