EFFICIENT MESSAGE CONSUMPTION IN A POINT-TO-POINT MESSAGING ENVIRONMENT

摘要

A method and system for assigning a message to an application instance are disclosed. Message processing times of a currently available application instance and a currently unavailable application instance are measured. An unavailable time of the currently unavailable application instance is approximated based on the estimated message processing time of the currently unavailable application instance. The unavailable time and estimated message processing time of the currently unavailable application instance are added to generate an updated processing time of the currently unavailable application instance. The estimated processing time of the currently available application instance and the updated processing time of the currently unavailable application instance are compared. If the updated processing time of the currently unavailable application instance is less than the estimated processing time of the currently available application instance, the currently unavailable application instance is selected to process the message. Otherwise, the currently available application instance is selected.
