In this tutorial, I’m going to show you how to set up a Kafka Consumer in a Spring Boot microservice so that it sends messages to a dead letter topic when something goes wrong. If you’re new to Kafka or Spring Boot, don’t worry – I’ll walk you through every step and explain everything clearly.…
Read More Kafka Consumer: Send Message to a Dead Letter TopicString comparison is a common task in Swift, and understanding how to perform case-insensitive comparisons is crucial. In this post, you’ll explore the basics of case-insensitive comparison of Strings through practical examples that will help you grasp this essential concept. Basics of String Comparison in Swift In Swift, comparing strings involves determining their order based…

You’ll see how to use specific settings to ensure that a single problematic message doesn’t disrupt your message processing. By the end, your consumer will be able to skip over errors and continue processing subsequent messages…
Read More Kafka Consumer: Handle Deserialization ErrorsIn this tutorial, you will learn how to configure Kafka Producer retries using two distinct approaches: The first approach utilizes the spring.kafka.producer.retries and spring.kafka.producer.properties.retry.backoff.ms configuration properties to define the number of retry attempts and the delay between them. The second approach involves the spring.kafka.producer.properties.linger.ms and spring.kafka.producer.properties.request.timeout.ms properties to manage the batching time and response timeout…

They are very useful when you need to store data that has a specific association between a key and a value. However, sometimes you might want to remove certain items from the dictionary. In this tutorial, you will learn about different ways…
Read More Remove an Item From a Dictionary in SwiftIn 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…

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…
Read More Kafka Consumer Configuration in the @Bean MethodIn 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…
Read More Creating Kafka Consumer in Spring Boot MicroserviceWhen 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…

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…

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…

This tutorial builds upon the concepts you learned about how to Create a Function in Swift, Nested Functions, and Functions With Default Parameters. If you haven’t checked that out, I highly recommend you give…

Introduction A Kafka producer is a client that sends messages to a Kafka topic, which is a logical name for a stream of records. A Kafka producer can specify various configuration properties to control…

This tutorial will guide you through the various ways to add items to a Swift dictionary, from the simplest syntax to more advanced techniques. 1. Add Item to Dictionary Using Subscript Syntax This…
Read More Add Item to a Dictionary in SwiftDictionaries in Swift are like containers that hold pairs of information: a key and its corresponding value. Think of them as organized lists where each item has a unique label (key) associated with some data (value). In this tutorial, you will learn how to create a new, empty dictionary in Swift. There are a few…
