Stepping is a distributed BASE jobs implementation. You can use it as a workflow engine, event outbox/inbox, email/SMS sender, remote invoker, and more.
It can also work with a DB transaction and supports the multi-DB scenario. That means the jobs are ensured to be eventually done after the DB transactions commit. You don't need to worry about inconsistencies caused by the app crashes after the transaction commit but before the steps are executed.
The distributed transaction is based on DTM's 2-phase messaging pattern.
Step in Stepping?
Job is a distributed transaction unit, and
Step is a specific task inside a job.
A job contains some steps, and the TM will execute them in order. If step 1 fails, it will be retried until success, and then step 2 starts to execute.
The TM will eventually complete the added steps:
var job = await distributedJobFactory.CreateJobAsync(); job.AddStep(new CreateOrderStep(orderCreatingArgs)); job.AddStep<SendOrderCreatedEmailStep>(); await job.StartAsync();
The Steps document shows how to define a step.
If you want to execute the steps after a DB transaction commits and ensure they will eventually be done:
var db = serviceProvider.GetRequiredService<MyDbContext>(); // example for EF Core await db.Database.BeginTransactionAsync(); var order = new Order(args); db.Orders.Add(order); await db.SaveChangesAsync(); var job = await distributedJobFactory.CreateJobAsync(new EfCoreSteppingDbContext(db)); job.AddStep(new SendOrderCreatedEmailStep(order)); job.AddStep(new SendOrderCreatedSmsStep(order)); await job.StartAsync(); // it will commit the DB transaction
ADO.NET(coming soon), and
For details, please see the Usage document.
See the Installation document.
Supported Transaction Managers
Stepping requires transaction managers. You can choose an implementation you like.
DTM is a mature transaction manager you can use as the TM provider for Stepping. DTM allows you to get many other distributed transaction modes like SAGA, TCC, and XA.
See the DTM document.
Stepping provides a simple built-in TM implementation. It runs with your app as a local transaction manager. Which app starts a job should be the TM of this job.
See the Local-TM document.
