Hi @spmallette !
While still keeping a websocket port for interactive console usage, our
server side provides a gRPC port for production traffic, which has such
constraints:
- Does not support session (conflicts with connection pooling and load
balancing)
- Bytecode only (server requires `"processor": "traversal"`, rejecting
string queries likely for performance, security and stateless design)
`gremlingo.DriverRemoteConnection` is tightly coupled to websocket transport
so we created a custom GrpcRemoteConnection. They look basically similar, take
the `SubmitByteCode` function as an example:
1. We extract the bytecode from gremlin traversals (standard API)
2. Serialize with `gremlingo.MakeBytecodeRequest` and
`GraphBinarySerializer.SerializeMessage` **exposed in this PR**
3. Send it over gRPC instead of websocket
4. Deserialize with the `GraphBinarySerializer.DeserializeMessage`
**exposed in this PR**
5. Return standard `ResultSet`
