Community Picks·4yTop 10 Microservices Design Patterns and Principles
Microservice architecture is structured on the business domain and it's a collection of small autonomous services. Transaction management is the fundamental advantage of a shared database versus a per-service database. Event Sourcing is based on the idea that any change in an entity's state should be captured by the system. The persistence of a business item is accomplished by storing a series of state-changing events.

CockroachDB·4ySQL Performance Best Practices
A distributed database can distribute the query and most of the work of the sort operation, but can’t reduce the workload without using an index. This index is ordered by email, enabling the server to isolate only the user’s messages, and ignore the other 999,000 in the table. It still has 3 stages, but when you take a closer look, the scan stage only touches 1,000 rows.
