What are the best practices for event sourcing?

Event sourcing is a powerful pattern. Key practices include using immutable events, ensuring event versioning, and maintaining a clear event schema.

Can you explain why immutable events are important?

Immutable events ensure that once an event is stored, it cannot be changed. This guarantees the integrity of the event log and allows for reliable event replay.

What should I consider for event versioning?

For event versioning, consider how changes to your event schema will affect existing events. Use techniques like event upcasting to handle changes gracefully.

How do I maintain a clear event schema?

Maintain a clear event schema by documenting your events, using consistent naming conventions, and regularly reviewing your event definitions.

Any tools you recommend for managing event sourcing?

Yes, tools like EventStore, Apache Kafka, and Axon Framework are popular for managing event sourcing effectively.
