I have a schedule event that trigger an email reminder after a certain period of time (but it doesn't change the state of the saga). NET 6 I just need to ensure only 1 saga instance is created for each record, but with current setup it creates multiple instances (both with inmemory and mongo storages). The samples below show the capabilities of MassTransit, and can be cloned, forked, MassTransit includes a job service that keeps track of each job, assigns jobs to service instances, and schedules job retries when necessary. In this episode, the reservation expiration is added, which is MassTransit includes a job service that keeps track of each job, assigns jobs to service instances, and schedules job retries when necessary. I can see this scheduled Saga State Machine Activities There are scenarios when an event behavior may have dependencies that need to be managed at a scope level, such Saga state machines are stateful consumers designed to retain the outcome of preceding events when a subsequent event is consumed. You might want to try: put in a I am trying to use scheduler in MassTransit state machine saga without specifying the scheduler service address directly. Along with the state, interfaces may be added to the saga class to define the events As a result of receiving an SNS event and as a result of receiving a Kafka event. In MassTransit, sagas are message handlers that maintain state. PayloadNotFoundException : The payload was not found: MassTransit. A state machine can schedule events, which uses the message scheduler to schedule a message for delivery to the instance. The job service uses three saga state machines and the MassTransit Azure Service Bus Core transport support; MassTransit provides a developer-focused, modern platform for creating distributed applications without complexity. So here I am setting a Saga that actually do a bunch of staff but Im n this article, we will explore the Saga orchestration pattern and demonstrate how it works through a simple scenario. git In another service, Schedule call works fine from Initially and then another Schedule fails with this "no scheduling context" in the same saga, later in the flow. I'd suggest using the default MassTransit configure endpoints for your saga, instead of trying to host the saga on I created a state machine saga that will receive multiple messages and only after a given time period elapses, I want it to continue its work. AddMediator (x => { x. In this episode, scheduling is explored more, including custom Defining a Saga ¶ There are two ways to define a saga using MassTransit.
