dsService Tracker Service

Overview

This service is part of the Expense Tracker application, responsible for processing and handling expense-related data. It accepts incoming HTTP POST requests, processes the data using a custom service, and produces messages to a Kafka topic. This setup allows the application to handle expense tracking in a scalable and distributed manner.

• Custom Message Service: Handles the business logic for processing expense data.
• Environment Configuration: Uses environment variables for flexible configuration.
