The Codiga team joined Datadog and integrated their static analyzer product with Datadog's infrastructure to release Datadog Code Analysis. The initial integration faced challenges due to limited support for certain languages, slow parsing, and performance issues. To address these shortcomings, the team migrated from ANTLR to Tree-sitter, a popular parsing library that supports multiple languages, including Rust. This migration enabled significant performance improvements, tripling analysis time and reducing memory usage by tenfold. The team also learned Rust from scratch and adapted their existing Java codebase to Rust, leveraging tools like rust-clippy and rustfmt for linting and code formatting. The new Rust-based static analyzer is now available as a binary and can be embedded directly into the IDE, providing faster feedback on coding errors and suggesting fixes in real-time.
