Design Microservices Architecture with Patterns and Principles - When to Use NoSQL Databases?

The video discusses when to use NoSQL databases, highlighting their flexible schema, suitability for dynamic and high-volume data, and ability to scale horizontally. It covers use cases like IoT applications, where data attributes are unpredictable. NoSQL databases prioritize partition tolerance and eventual consistency, making them ideal for handling big data and high-velocity data. They offer fast write operations but are not suited for complex join queries. The decentralized structure of NoSQL databases allows for scalability across geographical zones, making them a good choice for microservices.
