Building Real-time CSV File Generation with Kafka Consumers in C#

In this blog post, we'll explore how to create a real-time CSV file generation system using Kafka consumers in a C# application. Our goal is to configure up to 5 Kafka consumers, read data from a database table, and generate a CSV file whenever an update operation occurs in the table. We'll walk through each step of the process and provide code snippets to illustrate the implementation.

First, let's configure Kafka consumers in the appsettings.json file. We'll define settings for up to 5 consumers, specifying topics, group IDs, and other relevant parameters:
