Graeme developed an MVP for GraphQL query complexity control within the grafbase/grafbase repository, focusing on backend development and configuration management. He introduced configurable limits to manage query complexity, allowing teams to enforce resource constraints and prevent overly complex queries. The solution leveraged GraphQL schema directives, enabling users to customize and enable these controls according to their needs. Graeme documented the configuration process in Markdown and updated the changelog to communicate the new feature to users. This work provided a foundational mechanism for query governance, addressing potential performance issues and laying the groundwork for more robust query management in the future.
