In this episode my colleague Yvonne Ceelie and I talked about Set Based Validation and Sagas in Axon Framework.

We discussed:

Set Based Validation

• What is a 'set' and what is the meaning of 'set based validation'?
• What about an example?
• Two Models in CQRS: Command and Query Models
• How can we ensure consistency?
• Aggregates and consistency rules in Aggregates
• How about Parameter Resolvers?

Saga:

• Similarities and differences between Sagas and Aggregates
• Sagas in Axon vs. Saga database patterns - the new name for Sagas in Axon
• Managing complex business processes
• Annotations for Saga
• Test fixtures for Sagas in Axon Framework
• Some things to keep in mind when using Sagas
