US Patent 10554604 Low-load message queue scaling using ephemeral logical message topics

A messaging middleware platform implemented on a computer system. The platform comprises a directory service application that maps logical to physical topic references, where the physical topic references refer to message topics instantiated on message broker instances, a plurality of message producer instances that execute on the computer system, where each message producer instance stores messages on message topics instantiated based on a logical topic reference built into the message producer and dereferenced to a physical topic reference at run-time, and a workflow manager application that executes on the computer system that creates new message broker instances when the message depth exceeds a predefined threshold, revises associations between logical topic references and physical topic references in the directory service application, and causes the message producer instances to be reconfigured to dereference the logical topic reference to a physical topic reference associated with the new message broker instances.
