Ryan Kelleher enhanced SQL cursor documentation in the cockroachdb/cockroach repository by implementing support for the WITH HOLD and WITHOUT HOLD syntax. He updated the documentation generator, leveraging Go and BNF grammar, to recognize and accurately represent these new cursor options in both textual documentation and generated diagrams. This work focused on improving the clarity and completeness of SQL cursor documentation, making it easier for developers and users to understand cursor behavior. By refining code generation and documentation processes, Ryan’s contributions reduced onboarding time and support queries, demonstrating a thoughtful approach to developer experience and technical communication within the project.
