Configuring retries on the bus configurator works - the attempt count increments as expected.

The issue seems to only occur when retries are configured at the Consumer level.

Run the console app, it should demonstrate that the attempt count does not increment with each retry, outputting 0 each time.

Connect the Consumer and configure to use Immediate retries using UseRetry(.).

Then throw some exception to trigger the retries. The Consume method should invoke the context.GetRetryAttempt() method - logging it out for example.

Create a Consumer for the YourMessage event.

Create a new console app based on the QuickStart example in the MT docs.

In here I am not going to describe in details how to create. Publisher Application Implementationġ.) Create Asp.net core 3.1 web Api application using visual studio. They manage state and track any compensations required if a partial failure occurs. Sagas are designed to manage the complexity of a distributed transaction without locking and immediate consistency. Sagas are initiated by an event, sagas orchestrate events, and maintain the state of the overall transaction. Tracing and Monitoring Using the tracing functionality, you can get very detailed timings of when and where things were consumed, how long the receive took, how long the consume took and what exceptions were thrown. Unit Testability MassTransit provide TestFramework NuGet package. Routing MassTransit provides a heavily production tested convention for using RabbitMQ exchanges to route published messages to the subscribed consumers. Serialization MassTransit provides a number of serializes, including BSON, JSON, XML and Binary. Transactions MassTransit manage the transaction and also it will manage the database transition also it also support Entity Framework integrations. If the retries are comes to the max-retry count due to continued failures or other reasons, MassTransit moves the message to an error queue. Retries & Poison Messages If consumer throw an exception, MassTransit uses a retry policy to redeliver the message to the consumer. Threaded Consumers Multiple concurrent consumers possible, It will handle by the MassTransit, and also asynchronous message (The message pipeline in MassTransit is asynchronous).Įxception Management MassTransit implement some level of generic exception handling for consumers, then those messages moved to error queue and later we can inspect the message and re-queue it. What does MassTransit add on top of RabbitMQ? NET-based Enterprise Service Bus (ESB).MassTransit helps Microsoft developers route messages over MSMQ, RabbitMQ and ActiveMQ service busses, with native support for MSMQ and RabbitMQ. MassTransit is free/ open-source lightweight software. If the consumer consumes the message if there is a failure or exception occur system should be able to re-try and if the re-try unsuccessful then move the message to the Error queue. Use CaseĪssume that we have an application, Using that application user can create appointment after successfully create appointment publisher will publish email message to notify other parties, then consumer consume that message and trigger the email to the end-user. You can download the source code from my Git Repo. Install RabbitMQ cluster on Kubernetes or Openshift - To setup RabbitMQ cluster read my previous article Deploying RabbitMQ Cluster On Kubernetes - Part 1Īn also you should have a basic understanding of RabbitMQ, ASP.NET Core WebAPI, and.

If your using OpenShift Container Platform you should have basic knowledge on OpenShift and ( Provision Red Hat OpenShift Cluster On AWS) or you can use Red Hat OpenShift Developer Sandbox account ( Link), It will provide one month free Openshift cluster for you. Prerequisites & Setupīasic knowledge on Kubernetes architecture and its components ( Link) ,also you need to install Kubernetes cluster. To impalement publisher and subscriber we use MassTransit. In this article, we are going to talk about a simple publisher/subscriber scenario deployed on Kubernetes cluster. The main benefits of event-driven systems are asynchronous behavior and loosely coupled structures. When business events occur, producers publish them with messages. At the same time, other services consume them through event listeners. Event-driven microservice architecture, services communicate each-other using event messages.
