During October 2025, Triggan enhanced the VenkatasivareddyTR/aws-athena-query-federation repository by improving documentation for Neptune integration with Athena Federated Query. Focusing on developer experience, Triggan clarified how multi-valued properties, particularly array datatypes, should be handled when queried through Athena. The updated Markdown documentation explains approaches for representing arrays as delimited strings or returning only the first value, providing practical guidance for users integrating Neptune with Athena. This work, centered on documentation and technical communication, addressed a nuanced aspect of data representation, ensuring that developers can reliably interpret and manage multi-valued properties in their federated query workflows.
