The Bitrise Build Cache for Gradle is a feature that enables users to store and reuse outputs from previous CI builds, reducing build times by up to 10x. The cache hit rate metric indicates the percentage of times a build artifact is found in the cache, with higher rates indicating effective caching of frequently used dependencies and build artifacts. Bitrise Insights provides a user-friendly UI for analyzing cache hit rates, allowing users to identify areas that require attention and optimize their cache configuration. By drilling down into individual components such as Pipelines, Stages, Steps, and tasks, users can pinpoint root causes for low cache hit rates and take proactive measures to improve performance. The feature is available in Bitrise Insights and offers alerts to notify users when their cache hit rate falls below a certain threshold, empowering them to take action promptly. Upcoming updates will introduce new features such as Gradle Task Duration and network usage metrics to further enhance build performance analysis.
