There are some projects that require a massive amount of time to run specific features: an e-commerce scenario or a system that needs to send an email when a payment process is confirmed by the payment provider. As a developer, we know that keeping users waiting isn’t an option.
In the case of the payment, the application needs to send an email when the payment is complete. Creating a queue of tasks to be executed asynchronously is an excellent way to process a large quantity of data without impacting users, keeping them happy. The goal of this post is to talk about how to create these asynchronous calls with Java using Spring and RabbitMQ.
