Saga Pattern
Explore the saga pattern to manage distributed transactions in microservices, ensuring data consistency through compensating actions during failures. Understand how AWS Step Functions orchestrate workflows, handle errors, and maintain resilient systems by coordinating service interactions in complex transactions.
We'll cover the following...
What is a saga pattern?
The saga pattern is a design pattern used to manage distributed transactions in a microservices architecture. It helps ensure that in a system with multiple services, a sequence of operations is either fully completed or, if any operation fails, compensatory actions are taken to revert the system to a consistent state.
Analogy
The saga pattern can be thought of as a theatrical play with multiple acts, where each act represents a service or operation in a complex transaction within a distributed system. AWS Step Functions or other orchestration tools serve as the director, coordinating the execution and managing the flow of the performance.
In a distributed system, each ...
