Worked on modernizing the Dependency and Metrics API within the prisma/prisma-engines repository, focusing on enhancing stability and maintainability. The approach involved updating core Rust crates, specifically mobc and metrics, to their latest versions and refactoring metric recording by replacing macros with direct API calls. This transition improved observability and streamlined the codebase, while updates to Cargo.toml ensured compatibility with the new dependencies. The work laid a foundation for future crate-driven enhancements, making the metrics path cleaner and more maintainable. Skills applied included API updates, dependency management, and Rust, with an emphasis on preparing the engine for future feature development.
