问题
I am looking for a way to change the steps in the saga, example: insert a step during the processing, preferablly during runtime
Is it possible to do using sagas?
回答1:
Sagas (particularly those written using Automatonymous) were not designed to handle dynamic configuration at runtime. They are a codified way to create process monitors and workflows.
If you need to dynamically modify the steps of a workflow, you could use the Courier routing slip, which is built into MassTransit. It allows an activity in the workflow to revise the itinerary, adding or removing steps (activities) as needed.
