I’m a software developer with a passion for teaching. I’ve written lots of articles for AppsDeveloperBlog.com and made plenty of video tutorials on my YouTube channel(https://youtube.com/@SergeyKargopolov). If you want to dive deeper, I’ve also got some courses on Udemy(https://www.udemy.com/user/sergeykargopolov/) you might like.

When I’m not coding, I love to travel. I also share my travel adventures over at TravelLocalCanada.com. Hope to see you around on one of these platforms!

In a previous tutorial, you delved into the fundamentals of Swift closures, understanding their syntax, and exploring their practical applications. Building upon that knowledge, let’s explore the powerful realm of closures with multiple parameters. Understanding Closures According to Swift’s Official Documentation, closures are functional blocks in Swift that can be assigned to variables, passed as…

In this tutorial, I will guide you through the process of setting up a Kafka Consumer using the @Configuration class and the @Bean method. This approach offers more flexibility and control compared to using the application.properties file. Kafka consumer configuration can be achieved in two primary ways in a Spring Boot application: Using the application.properties…

In this tutorial, I will guide you through setting up a Kafka Consumer in a Spring Boot application. You will learn how to configure the consumer properties, create a listener class using the @KafkaListener annotation, and how to process messages with the @KafkaHandler annotation. Let’s start with the configuration. Kafka Consumer Configuration in application.properties In…

When you send out messages in Kafka, it’s essential to know they’ve been received and saved properly. That’s where two important settings come in: spring.kafka.producer.acks and min.insync.replicas. These settings help ensure that your messages are safely stored and acknowledged by the Kafka brokers. In this tutorial, I’ll explain what these settings are, how to configure…

In Apache Kafka, the min.insync.replicas configuration plays a crucial role in ensuring data durability and resilience. This setting determines the minimum number of replica copies (or in-sync replicas) that must acknowledge the receipt of a record before the producer can consider the write operation successful. Let’s break this down: Replicas: Think of these as backup…

In Swift, a dictionary is a data structure that stores information in key-value pairs. You can iterate or loop through a dictionary to access the keys and values within the loop. There are several ways to achieve this, including using  for-in loops and forEach methods. Using a For-In loop The for-in loop is a simpler way to iterate…
