API derived Flask app that tracks Auction Bids on items.

This simple projects exposes 4 APIs to do the following:

• record a user’s bid on an item.
• get the current winning bid for an item.
• get all the bids for an item.
• get all the items on which a user has bid.

Currently, it's a very naive solution.

Downsides to tackle:

• Concurrent realtime bid tracking for all users
  • Suggested solution using WebSocket Protocol and broadcast the changes in realtime.
• DBMS to handle structured data PostgreSQL
  • Table for users.
  • Table to items.
  • Table for bids with foreign key to user and item.
• Performance Cautions:
  • Handle N+1 queries for Bids by using DB JOINS.

Development is running using on bar metal.
