Protocols HTTP/REST

GES's cloud API is a proprietary HTTPS REST API; Gremlin (and Cypher) statements are sent as a string inside a POST body to a REST action endpoint, not through TinkerPop's own Gremlin Server HTTP channel, so 'Gremlin (HTTP)' from the draft is dropped.

This section describes the structure of a REST API on the service plane of GES.

Language C++

No official Huawei documentation states the implementation language; this rests on a single third-party technical article describing the EYWA kernel's development.
