Comparing Various Methods of Distributed Transactions
Explore three key methods for managing consistency across distributed systems: the two-phase commit protocol, choreographed sagas, and orchestrated sagas. Understand their workflows, benefits, challenges, and practical use cases to help you choose the appropriate approach for your event-driven architecture projects.
