Worked on enhancing the aws-athena-query-federation repository by improving documentation for Neptune integration with Athena Federated Query. Focused on clarifying the handling of multi-valued properties, particularly array datatypes, the work provided detailed guidance on representing these as delimited strings or returning only the first value. This update, implemented using Markdown and documentation best practices, aimed to improve the developer experience and reliability when querying Neptune through Athena. The contribution addressed a specific gap in the README, ensuring that developers have clear instructions for managing array data, and demonstrated attention to detail in technical communication and documentation structure.
