Reddoxx.Quartz.MongoDbJobStore.Redlock 2.0.0

MongoDB Job Store for Quartz.NET

Fork of the awesome codebase of @glucaci with multiple tweaks:

• Latest .net support
• Quartz cluster support
• DI-based configuration
• Improved locking support

Limitations

• Due to the nature of the DI-based approach multiple schedulers are not supported on the same host (SchedulerBuilder.Build()).
• The locking mechanism has been rebuilt to use a SELECT FOR UPDATE approach, which requires transactions. So your MongoDb needs to run in a replica-set configuration. We also provide a way to use redis instead of mongodb transactions for locking (using the redlock algorithm).

Nuget

Install-Package Reddoxx.Quartz.MongoDbJobStore

Basic Usage

First, create your own QuartzMongoDbJobStoreFactory, which provides the a database-instance where your collection should be stored in. The JobStoreFactory itself also needs to be added to your DI-Container as it'll be resolved by the MongoDbJobStore later on.

internal class QuartzMongoDbJobStoreFactory : IQuartzMongoDbJobStoreFactory
{
    private const string LocalConnectionString = "mongodb://localhost/quartz";

    private readonly IMongoDatabase _database;

    public QuartzMongoDbJobStoreFactory()
    {
        var url = new MongoUrl(LocalConnectionString);
        var client = new MongoClient(url);

        _database = client.GetDatabase(url.DatabaseName);
    }

    public IMongoDatabase GetDatabase()
    {
        return _database;
    }
}

Next, register your QuartzMongoDbJobStoreFactory in your DI-Container:

    // Make your job store factory available to the MongoDbJobStore
    services.AddSingleton<IQuartzMongoDbJobStoreFactory, QuartzMongoDbJobStoreFactory>();

Then we can configure quartz for the host. Be sure to specify MongoDbJobStore in q.UsePersistentStore<MongoDbJobStore> as this registers the MongoDbJobStore singleton as well. storage.ConfigureMongoDb(c => ...) allows for further customization.

    services.AddQuartz(
        q =>
        {
            q.SchedulerId = "AUTO";

            q.UsePersistentStore<MongoDbJobStore>(
                storage =>
                {
                    storage.UseClustering();
                    storage.UseNewtonsoftJsonSerializer();
    
                    // Your custom job store configuration
                    storage.ConfigureMongoDb(
                        c =>
                        {
                            // Configure your custom collection prefix
                            c.CollectionPrefix = "CustomPrefix";
                        }
                    );
                }
            );
        }
    );

Use redlock for locking instead of mongodb transactions

Install-Package Reddoxx.Quartz.MongoDbJobStore.Redlock

    // Add the DistributedLocksQuartzLockingManager to your DI container
    services.AddSingleton<IQuartzJobStoreLockingManager, DistributedLocksQuartzLockingManager>();
