This project simulates a ticket booking system to demonstrate various concurrency patterns in Go, including goroutines, channels, mutexes, and worker pools.
The goal of this project is to simulate a scenario where multiple users try to book a limited number of tickets concurrently. The system handles concurrent booking requests using a worker pool and ensures that no more tickets are booked than available. Additionally, it tracks the number of successful and failed booking attempts.
- Goroutines: Lightweight threads managed by the Go runtime to handle concurrent booking requests.
- Channels: Used for communication between the main function and worker goroutines.
- Mutex: Ensures safe access to shared data (total and booked tickets) between multiple goroutines.
- Worker Pool: Limits the number of concurrent booking attempts to a manageable level.
The TicketBookingSystem struct maintains the total number of tickets, the number of booked tickets, and the number of failed booking attempts. It uses a mutex to ensure that the ticket booking process is thread-safe.
The WorkerPool struct manages the workers that process booking requests. It includes the number of workers, channels for requests and results, and a wait group to synchronize the workers.
The BookTicket method of TicketBookingSystem checks if there are any tickets left and, if so, books a ticket. Otherwise, it increments the count of failed booking attempts.
Each worker processes booking requests from the request channel and sends the result to the result channel. A random delay simulates real-world conditions where booking requests do not arrive all at once.
The main function initializes the ticket booking system and the worker pool, starts the booking process, and prints the results.
