Worked on the vespa-engine/vespa repository to enhance the command-line interface by enabling bulk document retrieval. Refactored the existing readDocument function into readDocuments, allowing the CLI to accept and process multiple document IDs in a single request. This update reduced network round-trips and improved efficiency for both developers and operators. The implementation involved backend integration and API interaction, with careful validation to ensure at least one argument is provided and updated usage examples to support multiple IDs. Developed entirely in Go, this feature lays the foundation for future batch and asynchronous retrieval capabilities, reflecting a focused and maintainable engineering approach.
