Distributed Transaction
Explore the concept of distributed transactions within event-driven architecture. Understand how transactions extend across multiple services to maintain consistency and atomicity. Learn the differences between local and distributed transactions, why distributed transactions are necessary, and how to manage challenges such as consistency, isolation, and rollback across components in complex systems.
We'll cover the following...
The distributed components of an application will not always be able to complete a task completely isolated. We have already seen how we can use messages to share information between components so that remote components can have the data they need to complete small tasks. Within a simple component, more complex tasks could utilize a transaction to ensure that the entire operation completes atomically.
Local transactions vs. distributed transactions
Let’s talk about local transactions for a moment and why we would want to emulate them as distributed transactions. We use transactions for the atomicity, consistency, isolation, and durability (ACID) guarantees they provide us:
The atomicity guarantee ensures that the group of queries is ...
