I’m working on a software development project that involves complex workflows with multiple stages and dependencies, and we’re using CircleCI to manage our CI/CD pipeline. I’m looking for advice on how to optimize our CircleCI configurations to handle complex workflows more efficiently, particularly with regard to parallelism and job dependencies. What are the best practices for structuring config files to improve performance and maintainability? Additionally, any recommendations on leveraging CircleCI features or plugins to streamline the build process and reduce overall build times would be highly appreciated. Insights on managing large-scale projects or integrating with other tools are also welcome.
