The Two-Phase Commit (2PC) Pattern: Ensuring Consistency in Distributed Systems The Two-Phase Commit (2PC) Pattern is a distributed protocol that guarantees all or none of the operations in a distributed system are successfully completed, ensuring data consistency and integrity. It is essential for achieving atomic transactions across multiple resources, such as databases or services, in distributed systems.

Two-Phase Commit (2PC) vs Outbox Pattern: Ensuring Data Consistency The Two-Phase Commit (2PC) Pattern and the Outbox Pattern are two prominent strategies for achieving data consistency in distributed systems. While they both solve similar problems, they employ different approaches. Let’s dive into these patterns to help you determine which is best suited for your application needs. Two-Phase Commit (2PC) Pattern The 2PC Pattern is a distributed protocol designed to ensure that all participants in a distributed transaction either commit or rollback their changes, maintaining data consistency across systems. ...
