Introduction to Distributed Transactions In the world of microservices, managing transactions that span multiple services can be a daunting task. Traditional ACID (Atomicity, Consistency, Isolation, Durability) transactions are not feasible when dealing with distributed systems, as they require all participants to be available and synchronized. This is where the Saga pattern comes into play, offering a flexible and resilient approach to handling distributed transactions. What is the Saga Pattern? The Saga pattern is a design approach that manages distributed transactions by breaking them down into a sequence of local transactions....

If the chef fails to meet these expectations, you might be in for a surprise, and not the good kind. This scenario is eerily similar to how software components interact with each other, and that’s where Design by Contract (DbC) comes into play....
