What has changed about processing strategies in Mule 4?

In Mule 4, the approach to processing strategies has evolved significantly compared to earlier versions. In Mule 3, different processing strategies, such as synchronous, asynchronous, and non-blocking processing, were part of the core framework, allowing developers to manage how and when data was processed.

The key change in Mule 4 is that these specific processing strategies have been restructured and are no longer explicitly defined in the same way as in previous iterations. Instead, Mule 4 introduces a more straightforward model that focuses on simplicity and standardization. This redesign aims to allow developers to concentrate more on the business logic of their applications, with the underlying processing handled automatically by the runtime.

Therefore, the assertion that processing strategies have been completely eliminated reflects this fundamental change in how Mule 4 manages processing, prioritizing a streamlined and intuitive developer experience over the complexity of manual setting and configuration of multiple processing strategies. The focus is now on using the built-in capabilities of Mule 4 to automatically handle the execution flow based on the context of the application, enhancing productivity and reducing the chances of errors.
