E4, User Story 2: As an owner, I want to handle concurrent booking requests without conflicts.

[OisinWrites]

Tasks:

1. Analyze the current concurrency control mechanisms in the application to identify potential conflicts in booking requests.
2. Evaluate the database transaction isolation level to ensure it allows for concurrent booking requests without conflicts.
3. Implement optimistic locking or versioning mechanisms to handle concurrent booking requests.
4. Design and implement a reservation hold mechanism to reserve the selected table and time slot temporarily while the user completes the booking process.
5. Implement concurrency control logic to prevent conflicts when multiple users try to book the same table and time slot simultaneously.
6. Handle cases where a concurrent booking request conflicts with an existing booking, ensuring that only one booking is accepted.
7. Provide appropriate feedback or error messages to users in case of conflicts, guiding them to select an alternative table or time slot.
8. Test the concurrency handling functionality with multiple concurrent booking requests to verify its effectiveness and correctness.
9. Consider implementing retry mechanisms or queuing systems to handle high concurrency scenarios gracefully.
10. Monitor and log any instances where conflicts occur during concurrent booking requests for further analysis and troubleshooting.
11. Continuously review and improve the concurrency handling mechanisms based on user feedback and system performance.
12. Ensure that the performance of the application is not significantly impacted by the concurrency control mechanisms.

By breaking down User Story 2 into these tasks, you can effectively plan and implement the necessary measures to handle concurrent booking requests without conflicts, providing a seamless and reliable booking experience for both owners and users on your restaurant booking site.
