When we talk about event-driven architectures, we often focus on things like loose coupling, scalability and DDD. But under the hood, the way consumers receive events matters just as much. And it usually comes down to one of two models: push vs poll. Your choice dictates what service(s) you use and how you handle errors. So, in this article, let’s compare the two models and understand their pros & cons. The post Understanding push vs poll in event-driven architectures appeared first on theburningmonk.com.

Serverful (i.e. paying for uptime) services like RDS makes working with ephemeral environments more difficult and poses a cost concern. In this artcile, let's see how Neon's Serverless Postgres database solves this problem and how we can clone an existing database instantly by branching from it. We will see how Neon differs from Aurora Serverless v2 and give you a step-by-step guide on how to use Neon with ephemeral environments in both your day-to-day feature development work, as well as in CI/CD pipeline[...]

What if you don't have to worry about event versioning or catching breaking changes anymore? What if event consumers are no longer coupled to the schema of the event and instead, subscribe to their semantics? I discovered an exciting new way to manage event schemas that will blow your mind!

The rule of three suggests that if you encounter the same pattern for the third time in your code, you should refactor it into a reusable abstraction. The same thing applies in programming language theory. When you find that you are doing the same thing for the third time, it is probably a good idea to stop and think - is there a general pattern? Figure 1. Auto-completion list showing possible operations in The Gamma In my PhD thesis on context-aware computations, I did exactly this. When we realised th[...]
