Design Microservices Architecture with Patterns and Principles - Database Sharding Pattern

The video tutorial explains the concept of sharding, which involves dividing a database into smaller, unique pieces called shards. This technique is used to improve scalability, performance, and availability in microservice architectures. Sharding allows for horizontal partitioning, balancing workloads, and enhancing data access efficiency. The tutorial also covers the role of partition keys in organizing data and the benefits of sharding, such as increased security and data measurement. Overall, sharding provides a high level of control over data distribution and is beneficial for managing large volumes of data.
