I think Huawei's Graph Engine Service meets the requirements for the index listing:
https://groups.google.com/d/msg/gremlin-users/TEJuwsCuQcE/yjbOlmz8CwAJ I think the listing would just be taken from their description: Huawei Graph Engine Service - a fully-managed, distributed, at-scale graph query and analysis service that provides a visualized interactive analytics platform Unless there are objections in the next 72 hours, I will go ahead an get this added. Thanks
