Real-Time Event Ticketing System with Producer-Consumer Pattern

Overview

The Real-Time Event Ticketing System is a simulation designed to manage ticket sales and purchases using the Producer-Consumer pattern. The system ensures concurrency management, allowing multiple vendors to release tickets and customers to retrieve them simultaneously in a real-time environment.

The project is built using Java for core functionalities, with a web application interface developed using React/Angular, Spring Boot, and MySQL.

Features

• Real-Time Ticket Transactions: Simulates real-time ticket release and purchase.
• Concurrency Control: Implements the Producer-Consumer pattern for efficient handling of ticket operations.
• Dynamic Configuration: Allows users to configure ticketing parameters through a frontend interface.
• Persistence: Saves and retrieves configurations and logs using a MySQL database.
• User-Friendly Web Interface: Provides an intuitive interface for running simulations and viewing results.

Tech Stack

• Frontend: React
• Backend: Spring Boot
• Database: MySQL
• Core Language: Java

    "customers": 3,
    "releaseRate": 1000,
    "retrievalRate": 500
  }

• Response:

  {
    "status": "Simulation started",
    "simulationId": "12345"
  }

2. Stop Simulation

• Endpoint: /api/simulation/stop
• Method: POST
• Request Body:

  {
    "simulationId": "12345"
  }

• Response:

  {
    "status": "Simulation stopped",
    "summary": {
      "vendors": [...],
      "customers": [...]
    }
  }

3. Save Configuration

• Endpoint: /api/configurations/save
• Method: POST
• Request Body:

  {
    "name": "Config1",
    "ticketCapacity": 10,
    "totalTickets": 8,
    "vendors": 2,
    "customers": 3,
    "releaseRate": 1000,
    "retrievalRate": 500
  }

• Response:

  {
    "status": "Configuration saved",
    "configId": "67890"
  }

4. Load Configuration

• Endpoint: /api/configurations/load/{configId}
• Method: GET
• Response:

  {
    "configId": "67890",
    "name": "Config1",
    "ticketCapacity": 10,
    "totalTickets": 8,
    "vendors": 2,
    "customers": 3,
    "releaseRate": 1000,
    "retrievalRate": 500
  }

5. Get All Configurations

• Endpoint: /api/configurations
• Method: GET
• Response:

  [
    {
      "configId": "67890",
      "name": "Config1",
      "ticketCapacity": 10,
      "totalTickets": 8,
      "vendors": 2,
      "customers": 3,
      "releaseRate": 1000,
      "retrievalRate": 500
    },
    ...
  ]

6. Delete Configuration

• Endpoint: /api/configurations/delete/{configId}
• Method: DELETE
• Response:

  {
    "status": "Configuration deleted"
  }
