The default is 'Quartz. PropertySettingJobFactory', which simply calls Activator.

CreateInstance with given type to produce a new instance each time execution is about to occur. Represent a name-value pair that will be placed into the "scheduler context" as strings see IScheduler.

So for example, the setting "quartz. Put "MyKey", "MyValue". The maximum number of triggers that a scheduler node is allowed to acquire for firing at once. Default value is 1. The larger the number, the more efficient firing is in situations where there are very many triggers needing to be fired all at once - but at the cost of possible imbalanced load between cluster nodes.

The amount of time in milliseconds that a trigger is allowed to be acquired and fired ahead of its scheduled fire time. Defaults to 0. The larger the number, the more likely batch acquisition of triggers to fire will be able to select and fire more than 1 trigger at a time - at the cost of trigger schedule not being honored precisely triggers may fire this amount early. Is the name of the ThreadPool implementation you wish to use. The thread pool that ships with Quartz is "Quartz.

DefaultThreadPool", and should meet the needs of nearly every user. It has very simple behavior and is very well tested. It dispatches tasks to. NET task queue and ensures that configured max amount of concurrent tasks limit is obeyed. This is the number of concurrent tasks that can be dispatched to CLR thread pool. If you only have a few jobs that fire a few times a day, then 1 tasks is plenty! If you have tens of thousands of jobs, with many firing every minute, then you probably want a max concurrency count more like 50 or this highly depends on the nature of the work that your jobs perform, and your systems resources!

Also note CLR thread pool configuration separate from Quartz itself. If you use your own implementation of a thread pool, you can have properties set on it reflectively simply by naming the property as thus:. Global listeners can be instantiated and configured by StdSchedulerFactory , or your application can do it itself at runtime, and then register the listeners with the scheduler. Configuring listeners through the configuration file consists of giving then a name, and then specifying the type name, and any other properties to be set on the instance.

The type must have a no-arg constructor, and the properties are set reflectively. Only primitive data type values including strings are supported. Like listeners configuring plugins through the configuration file consists of giving then a name, and then specifying the type name, and any other properties to be set on the instance. Only primitive data type values including Strings are supported.

There are several plugins that come with Quartz, that can be found in the Quartz. Plugins opens new window package. Example of configuring a few of them are as follows:.

The logging trigger history plugin catches trigger events it is also a trigger listener and logs then with logging infrastructure. Job initialization plugin reads a set of jobs and triggers from an XML file, and adds them to the scheduler during initialization. NET developers, used as a way of running background tasks on a timer, in a reliable, clustered, way.

Using Quartz. NET Core is pretty similar - Quartz. NET supports. NET Standard 2. NET Core has good support for running "background tasks" via way of hosted services. Hosted services are started when your ASP.

NET Core app starts, and run in the background for the lifetime of the application. NET version 3. Hosting package. Hosting can be used either with ASP. NET Core applications, or with "generic host" based worker-services.

There is also a Quartz. AspNetCore package that builds on the Quartz. It primarily adds health-check integration, though health-checks can also be used with worker-services too!

While it's possible to create a "timed" background service , that runs a tasks every 10 minutes, for example , Quartz. NET provides a far more robust solution. You can ensure tasks only run at specific times of the day e. NET also allows you to run multiple instances of your application in a clustered fashion, so that only a single instance can run a given task at any one time.

The Quartz. NET hosted service takes care of the scheduler part of Quartz. It will run in the background of your application, checking for triggers that are firing, and running the associated jobs as necessary.

You need to configure the scheduler initially, but you don't need to worry about starting or stopping it, the IHostedService manages that for you. In this post I'll show the basics of creating a Quartz.

NET job and scheduling it to run on a timer in a hosted service. NET is a. For this test I created a worker service project. You can install the Quartz. NET hosting package using dotnet add package Quartz. If you view the. This adds the hosted service package, which brings in the main Quartz. NET package with in. In ASP. NET Core applications you would typically do both of these in the Startup. ConfigureServices method. That's because Quartz. Take the Tour.
