npm version monthly downloads REUSE status CI Main

The Event-Queue is a framework built on top of CAP Node.js, designed specifically for efficient and streamlined asynchronous event processing. With a focus on load balancing, this package ensures optimal event distribution across all available application instances. By providing managed transactions similar to CAP handlers, the Event-Queue framework simplifies event processing, enhancing the overall performance of your application.

Additionally, Event-Queue provides support for periodic events, allowing for processing at defined intervals. This feature further extends its capabilities in load balancing and transaction management, ensuring that even regularly occurring tasks are handled efficiently and effectively without overloading any single instance. This makes it an ideal solution for applications needing consistent, reliable event processing.
