AtomicScheduler

Cron based scheduler for C# designed for multi-server applications.

Features:

Full Cron support
Atomic locks - reliably execute tasks on a single server for each execution interval
Overlapping prevention/mutex locks
ServiceStack.Redis support.

Working Example

// Initialize Redis Driver
var driver = new RedisAtomicDriver("localhost:6379"); // Connection string

// Additionally, you can use one of the following from ServiceStack.Redis
// var driver = new RedisAtomicDriver(redisManagerPool); // Service Stack IRedisManagerPool
// var driver = new RedisAtomicDriver(redisClient); // Service Stack IRedisClient

// Initialize new Scheduler
var scheduler = new Scheduler();
scheduler.SetAtomicDriver(driver);

// Add tasks
scheduler.AddTask(...);
scheduler.Run();

Atomic Locks / Cluster Support

If your application is running on multiple servers, you may limit a scheduled job to only execute on a single server by specifying oneMachineOnly as true when instantiating your ScheduledTask object.

var task = new ScheduledTask {
  ...
  oneMachineOnly = true,
  ...
}

Mutex Locking

If you are scheduling tasks that may potentially take longer than a minute and should overlap eachother, you should enable the allowOverlapping flag by specifying true.

var task = new ScheduledTask {
  ...
  allowOverlapping = true,
  ...
}

Contributing / Building Drivers

If you would like to add support for a medium that can interface with the scheduler, please extend the IAtomicDriver interface and make a pull request.
