DurableTask.Lava 1.5.0

DurableTask.Lava

This repo contains the library code to interact with Durable Task Framework (DTFx) in-memory using Netherite as the orchestration hub.

About

It contains wrappers, services, extensions, and other helper methods to configure and use TaskHubClient and TaskHubWorker as injectable services.

This configuration uses an in-memory orchestration hub; history, events, and other data are NOT saved when the application is not running.

Usage

Configuration

In the IHost ConfigureServices() configuration methods, use the extension methods to configure the Orchestration Hub and the Task services.

IHost.CreateDefaultBuilder(args)
	 .ConfigureServices((hostBuilderContext, services) =>
	 {
		// Adds:
		// - memory orchestration hub
		// - task worker
		// - task client
		// - scans for Orchestrations and Activities and registers them
		services.AddInMemoryOrchestrations();
	 })
	 .Build();

Orchestrations must be classes that implement TaskOrchestration<TOutput, TInput>. Activities must be classes that implement TaskActivity<TInput, TOutput> or AsyncTaskActivity<TInput, TOutput>. Orchestrations and Activities must be registered on the task worker (server) to function.

To start an Orchestration, inject an instance of the ITaskClient service and use the StartOrchestration or ScheduleOrchestration methods.
