JobRunr allows to create a one-off job by means the the enqueue function on the BackgroundJob class or the JobScheduler class. It is often used for one-off tasks or to distribute load over multiple servers. Direct execution: This type of scheduling is used when you want a job to be executed immediately.When it comes to scheduling jobs in Java, there are three main types of scheduling to consider: direct execution, scheduled execution in the future, and recurring execution by means of a cron expression. Additionally, JobRunr is designed with enterprise-grade capabilities, providing reliability, security, and support for large-scale production deployments. Unlike Quartz, which is quite a heavy and complex framework, JobRunr is a more modern, lightweight, and easy-to-use scheduler. integration with various frameworks including Spring Boot, Micronaut and Quarkus.distributed execution over different JVM instances.an embedded dashboard showing you the status of each job.a really easy API that allows you to schedule any job with just one line of code or by means of the annotation. While there are some other scheduler frameworks available for Java, including the standard and, Quartz and DB-Scheduler, JobRunr offers a number of advantages over these traditional frameworks. When it comes to choosing the best scheduler for Java, JobRunr stands out from the competition. This is useful for tasks such as sending emails, create recurring automated reports, batch import files from XML or JSON or performing any other type of automated task. It means that a virtual thread is created (instead of a heavy platform thread) for each task (for example, HTTP request at a controller), which is lightweight and leads to better performance.In Java, a scheduler is a tool that allows you to execute tasks or jobs at a specific time or after a specific interval. What does this mean? By the power of the that was introduced in Spring Boot 3.2, When virtual threads are enabled in the configuration, the applicationTaskExecutor bean, which is responsible for executing async tasks, and its type is SimpleAsyncTaskExecutor will configure to use virtual threads under the hood for each task. This means that your application code that is handling a web request, such as a method in a controller, will run on a virtual thread. When virtual threads are enabled, Tomcat and Jetty will use virtual threads for request processing. server.shutdowngraceful -per-shutdown-phase60s .await-terminationtrue. We can categorize the support for Virtual Threads and its effect in the Spring Boot applications (when we enable it!) into three categories:ġ- The Web MVC stack servlet containers (Tomcat and Jetty)Īccording to the Spring Boot 3.2 release note: In later versions of spring boot you can also set these properties via application.properties. To leverage this feature in your Spring Boot applications, you need to have a JDK 21 installed and enable the configuration. Now, Spring Boot has started to add support for this great feature in version 3.2, but there is still much room, and the Spring Boot team decided to add this support gradually. The most important advantage of Virtual Threads is that they improve the Scalability and Performance of Java applications by introducing a lightweight threading model while keeping backward compatibility and decreasing the complexity of asynchronous programming without sacrificing performance. There are a ton of articles out there about Project Loom and Virtual Threads in Java 21, and we do not want to repeat them. Virtual Threads, as the most important part of this project, was finally released in Java 21, although two other important parts of it, Scoped Values and Structured Concurrency, have not yet been released. Project Loom aims to provide lightweight concurrency and new programming models on the Java platform by exploring and delivering Java VM features and APIs. Support for Virtual Threads (Project Loom) Check the release notes page to view the complete list.ġ. This release introduces numerous new features and enhancements. Recently, Spring Boot Team announced the release of Spring Boot 3.2, and we are excited to share some of the most exciting features coming in the release.
