Quartz.NET-LiteDB

JobStore implementation for Quartz.NET scheduler using LiteDB.

About

Quartz.NET is a full-featured, open source job scheduling system that can be used from smallest apps to large scale enterprise systems. Quartz.NET on LiteDB is a new provider written for Quartz.NET which lets us use the LiteDB NoSQL database as the persistent Job Store for scheduling data (instead of the SQL solutions that are built-in Quartz.NET).

Quartz.NET on LiteDB is a provider that is forked and adapted to LiteDB from Quartz.NET on RavenDB.

Installation

First add scheduling to your app using Quartz.NET (example). Then install the NuGet package.

Configuration & Usage

.NET Framework

In your code, where you would have normally configured Quartz to use a persistent job store, you must add the following configuration properties:

// In your application where you want to setup the scheduler:
NameValueCollection properties = new NameValueCollection
{
    // Normal scheduler properties
    ["quartz.scheduler.instanceName"] = "TestScheduler",
    ["quartz.scheduler.instanceId"] = "instance_one",
    ["quartz.threadPool.type"] = "Quartz.Simpl.SimpleThreadPool, Quartz",
    ["quartz.threadPool.threadCount"] = "1",
    ["quartz.threadPool.threadPriority"] = "Normal",
    // LiteDB JobStore property
    ["quartz.jobStore.type"] = "Quartz.Impl.LiteDB.LiteDbJobStore, Quartz.Impl.LiteDB"
    // LiteDB Connection String
    ["quartz.jobStore.connectionString"] = "Filename=Quartz-Demo.db;",
};
// Init scheduler with the desired configuration properties
ISchedulerFactory sf = new StdSchedulerFactory(properties);
IScheduler scheduler = sf.GetScheduler();

.NET Core

For use in .NET Core Workers or ASP.NET Core use the recommended Fluent API when setting up a Quartz in ConfigureServices like:

var configuration = new ConfigurationBuilder()
                        .AddJsonFile("appsettings.json")
                        .Build();
var section = configuration.GetSection("MyService");
var config = section.Get<MyServiceConfig>();
services.AddQuartz(q =>
    {
        q.UseMicrosoftDependencyInjectionJobFactory();
        q.UseDefaultThreadPool(tp =>
        {
            tp.MaxConcurrency = 10;
        });
        q.UsePersistentStore(s =>
        {
            s.UseLiteDb(options =>
            {
                options.ConnectionString = "Filename=Quartz-Worker.db";
            });
            s.UseBinarySerializer();
        });
        
        // Add jobs and triggers as you wish
    }
);
services.AddQuartzHostedService(
    q => q.WaitForJobsToComplete = true);
