CQRS, an introduction by JC Bohin

Editor's Notes

  1. Pattern Commandes / tâches / mutation Requêtes / retourner valeurs
  2. CRUD
  3. Command : Validation, logique Query : Immutable, Usages : Performance (séparer) Scalabilité Sécurité Facilité de maintenir règles métier évoluent souvent, domaine model bouge Client-Centric API, gérer plusieurs vues Event-Based, Reactive Service Boundary, au sein d’un Domaine Simplifier transactions / acidité inter-services Task-Based UI Se prête bien aux Domain Events, Asynchronisme Risques : Complexité Hype (si ca tiens dans un CRUD, pourquoi chercher autre chose) Souvent eventual consistent Event Sourcing : Audit Replay Simplifier consistance transactions parallèles
