Multi-executor workflows provide the flexibility to run jobs across different platforms, such as Linux and macOS, and accommodate various programming languages within the same workflow, enhancing modularity and efficiency. These workflows allow teams to choose from multiple resource classes, enabling the configuration of CPU and RAM to match job requirements, which helps avoid memory constraints and optimize performance. Examples include Facebook React, which tests across Android, iOS, and tvOS platforms using different machine sizes to meet specific memory needs, and Envoy Proxy, which leverages multi-platform workflows to test across macOS and Linux while using varied resource classes to optimize resource usage. These approaches enable teams to perform simultaneous testing and build processes across multiple platforms, providing valuable feedback and ensuring that applications function correctly in diverse environments.
