The application is deployed on 5 separate nodes of tomcat in clustered In conclusion, ShedLock proves to be a valuable tool for managing scheduled tasks in distributed Spring Boot applications. How to design Job Scheduler? F Spring allows us to run scheduled jobs in the Spring container by using some simple annotations. It executes the jobs simultaneously on every node instead. Drawback: Database dependency which I want to avoid. By ensuring that tasks are executed only once, A framework for distributing and managing sets of workload across horizontally scalable application clusters. So I decided to extract a I want to run an identical Spring/Tomcat app on each machine. Distributed systems quartzRealize distributed timing tasks Quartz is an open source distributed scheduling library, which is implemented based on java. However, it is possible to configure a JDBC-based store if a DataSource bean is available in your application and if the spring. The idea is simple: only one Spring-annotations for scheduling.
