Abstract
In accordance with an embodiment, described herein is a system and method for providing a constant memory footprint concatenating reactive publisher, for use with microservices or reactive programming environments. A Publisher provides a Subscriber with a Subscription that supports requests of an amount up to a particular value. The Publisher can keep track of a requested number of items. When concatenating output from multiple Publishers, the switch between the output of one Publisher, and that of the next, may involve keeping track of new states. The described approach supports the requirement to maintain an amount of requests, by using request counters to maintain the necessary state, heed backpressure, and deliver requests as soon as they are issued by the Subscriber owning the Subscription.
