Ticketing System API

This repository contains a microservices-based ticketing system with support for CRUD operations, filtering, sorting, and event-driven communication using RabbitMQ and Elasticsearch.

Architecture Overview

The system follows a Domain-Driven Design (DDD) approach, employing:

• Golang for backend services
• Elasticsearch for search and storage of ticket queries
• RabbitMQ for handling events
• SQL Server for primary storage
• Swagger for API documentation

Project Structure

• application: Contains service logic and DTOs for managing ticket operations.
• domain: Defines entities for the system (e.g., Ticket).
• infrastructure: Manages external connections, including repositories and event handling.
• interfaces: Contains API handlers and request validation.

Key Features

• Create Ticket API: Allows support agents to create new tickets.
• Get Ticket List API: Supports filtering, sorting, and pagination.
• Event-Driven Updates: Ticket updates are published and consumed via RabbitMQ for Elasticsearch indexing.
