Interface IActivity<TData>
One unit of work in a workflow. Ordinary code with constructor DI — no determinism constraints apply, because progress is checkpointed rather than replayed (ARCHITECTURE.md §6.2).
public interface IActivity<TData>Type Parameters
TDataThe workflow's data document.
Remarks
Every execution runs as a Layer 1 job, so an activity inherits retries, backoff, leases, distribution and dashboard visibility rather than reimplementing them. It also inherits at-least-once execution: an activity may run twice if a worker dies after doing the work and before the checkpoint commits, so side effects should be idempotent.
Methods
- ExecuteAsync(ActivityContext<TData>, CancellationToken)
