First of all, thanks for your feedback, I really appreciate it. About your first point, I essentially agree with you. While I talk about "schemaless" data, I'm not really thinking on leaving it uncontrolled or letting each service write whatever they want to the DB. I'm thinking more on avoiding restrictions in the schema in order to extend the system for a specific retailer needs. We're planning to use a strongly typed programming language aiming for application-level data consistency, and we'll probably need to define a shared set of type definitions for the whole system and specially for the message passing protocol; but we also want to make it extremely easy to change so it can be adapted for the specific needs of each business. About the second point, yes, we definitely know this is a very ambitious project, but it can be broken into smaller projects that are more approachable, so we can target a smaller objective and re-evaluate after the first iterations. We won't achieve everything we want in a single step, but I'm sure we can walk in that direction. Here's where I think the open source approach can make a difference if we catch the attention of enough people. Choosing Swift is risky too, but we're really happy with that programming language and we believe that the only way to make it evolve to be a serious backend language is that some crazy people like us make a strong bet for it. And about the event-driven architecture, we believe that there are some specific problems in eCommerce that are specially suitable for this approach, but it's not definitely a silver bullet. For instance, the Magento core triggers all kind of events when different business objects are updated and we've found it to be really useful when you need to create an extension without touching the core. We see on events a way to decouple logic, so one module can trigger events without knowing who will be listening and the listeners can receive information without knowing who generated it. So yes! This is crazy, but after many years on this field using the same tools, we're really excited with the idea of bringing it into life! :-) |
