Developed tagging support for the datarobot_custom_model resource in the datarobot-community/terraform-provider-datarobot repository, enabling users to assign tags to custom models at creation for improved organization and governance. The work involved updating the resource schema, implementing client-side tag conversion logic in Go, and refactoring helper functions for reuse. Comprehensive unit and integration tests were added to ensure reliability, and documentation was updated to guide users on the new tagging functionality. By making tags write-once at creation, the solution streamlines model lifecycle management and enhances searchability, reducing manual overhead for teams managing custom models through Terraform.
