\ No newline at end of file +# InventorySim + +Simulates an single-warehouse inventory management system that handles these +edge cases by preventing inventory oversells under load. + +## Problem + +Inventory management systems are an intriguing area for system designs. They +must follow strict rules for how inventory is added, removed, and transferred +between locations in a warehouse. Without careful handling, stock can be +purchased that doesn't exist. + +For instance, a high traffic item can sell out quickly, but how can you prevent +two users from purchasing the last item at the same time? Race conditions happen +when multiple requests read and write the same inventory row at the same time. +Two customers can read only one unit of milk is available, both reserve it, and +the system oversells. |
