Design Microservices Architecture with Patterns and Principles - Problem: Dual Write Problem

The video tutorial discusses the dual write problem, which occurs when an application needs to change data in two different systems, such as a database and a message queue. This can lead to inconsistent states if one of the writes fails. The tutorial provides an example using microservices and explains why solving dual write problems is challenging. It also explores solutions like the transactional outbox pattern and change data capture (CDC) to avoid these issues in microservices.
