Change Data Capture (CDC) in Event-Driven Microservices

Change Data Capture (CDC) is a method for capturing and replicating database changes in real time, which is crucial for maintaining data consistency across systems in event-driven architectures. Unlike traditional ETL processes that operate on set intervals, CDC ensures systems remain synchronized by propagating changes as events, allowing for seamless data replication and zero-downtime cloud migrations. In the context of event-driven microservices, CDC captures data modifications at the database level and uses a messaging system to asynchronously distribute these changes as events to various microservices. Orkes Conductor, a leading orchestration platform, enhances this process by allowing developers to stream workflow state changes to external systems using CDC-enabled workflows. By enabling real-time detection and propagation of workflow state changes, Conductor facilitates smooth orchestration and synchronization between services, thus optimizing performance in microservice-based applications. This integration is simplified through the Orkes Developer Edition, which provides a sandbox environment for testing these capabilities, and Orkes Cloud, a fully managed service offering enterprise-grade orchestration.
