HIGH THROUGHPUT GLOBAL ORDER PROMISING SYSTEM

摘要

Techniques are disclosed for high-throughput order promising using multiple servers. Methods and apparatus provide item availability information by receiving an inquiry requesting availability status of a specified item, retrieving summary data associated with the item from a summary data structure stored in a memory of the computer system, determining availability data for the specified item based upon the summary data, and sending an inquiry response indicating the availability of the item based upon the determined availability data. Methods and apparatus provide order scheduling by receiving a scheduling request that identifies an item to be scheduled, determining a schedule for the item, storing availability information for the item based upon the schedule in an in-memory database, and sending a scheduling response based upon the schedule. Storing the availability information may cause the in-memory database to generate a notification that results in an update of the summary data structure.
