In software engineering, "coupling" means how much different parts of a software system depend on each other. If they are tightly coupled, changes to one part can affect many others. But if they are loosely coupled, changes to one part won't cause big problems in the rest of the system. Domain events are a Domain-Driven Design (DDD) tactical pattern that we can use to build loosely coupled systems. You can raise a domain event from the domain, which represents a fact that has occurred. And ot...| www.milanjovanovic.tech
Working with Microservices, or any distributed system for that matter, is difficult. In a distributed system many things can go wrong, and there are even research papers about this. If you want to explore this topic futher, I suggest that you read about the fallacies of distributed computing. Reducing the surface area for things to go wrong should be one of your goals, as an engineer. In this week's newsletter, we'll try to achieve exactly that using the Outbox pattern. How can you implement ...| www.milanjovanovic.tech
In this week's newsletter, I'll show you how you can remove repetitive conditions in EF Core database queries. An example would be when you implement soft-delete, and have to check if a record was soft-deleted or not in every query. Also, it is practical if you're working in a multi-tenant system and need to specify a tenantId on every query. EF Core has a powerful feature called Query Filters that can help you remove repetitive conditions from your code.| www.milanjovanovic.tech
I recently ran into an issue with Entity Framework Core. The query I was running was constantly timing out. So I used a new EF Core feature called Query Splitting to significantly improve my performance.| www.milanjovanovic.tech
