Best Practices2

CQRS (Command Query Responsibility Segregation)

An architecture pattern that separates the model that writes data (commands) from the model that reads it (queries), allowing each side to scale and evolve independently.

Best Practice

Event Sourcing

An architecture pattern that stores every change to application state as an immutable sequence of events, making the event log the source of truth instead of current state.

Patterns2

Pattern

Database per Service

Each microservice owns and manages its own database, enabling loose coupling and independent deployability

Pattern

Store state changes as a sequence of events rather than just the current state

Reference Architectures1

Reference Architecture

CQRS with Event Sourcing

Glossary

Event sourcing is a pattern that stores the full history of changes to application state as an immutable sequence of events, reconstructing current state by replaying those events rather than storing only the latest snapshot.
