A common and effective method of validating webhook requests incorporates the use of HMAC (Hash-based Message Authentication Code) SHA256, a timestamp and signature headers. These elements combined ensure that only verified requests are processed.
Webhooks offer a robust integration with third-party services, facilitating complex and time-consuming processes asynchronously. Yet, they present a high risk of missed events due to high latency or performance issues. In this blog post, I’ll guide you through a reliable and scalable solution for handling webhooks. The toolkit consists of Spring Boot, WebFlux, Kotlin coroutines, and Apache Kafka. I’ll show you how to build a system that efficiently enqueues incoming requests into an internal queue for background processing. So let’s delve into it!
Are you drowning in a sea of ghost branches? Have you ever scrolled through your local Git repository only to be overwhelmed by a convoluted tangle of orphaned branches? You’re not alone. Unused, stale, or obsolete branches can quickly amass in our workspace, creating a breeding ground for confusion and chaos. As developers, maintaining a clean and organized local repository is essential for efficient and error-free work. This blog post offers easy-to-follow steps on how to safely prune those redundant local Git branches that have lost their ties to the remote upstream. It’s time to trim away the excess, and clear the path for cleaner code and smoother collaboration.
The LazyInitializationException is a common occurrence when using Hibernate. It typically happens when you access a lazy-loaded association outside of the persistence context in which it was loaded. I will show you how to prevent this exception without compromising the performance of your application. Through the lens of Spring Data, I will explain how to resolve this challenge with a handy annotation: @EntityGraph. Implementing this strategy allows you to optimize both for efficiency and effectiveness, avoiding one of the common pitfalls in Hibernate.
Kotlin coroutines are a powerful tool that propels efficiency in dealing with concurrent programming. They enable to treat asynchronous code as if it was synchronous, making it easier to manage and understand. In this blog post, I explore some of the core principles of coroutines and compare their performance against conventional blocking calls.
