Serialize id type in to id string

[kmcginnes]

Description

Updates the VertexId and EdgeId value to include a prefix that represents the original type of the ID before being mapped in to Graph Explorer.

• Number ID type - (num)1234
• String ID type - (str)a6ca3117-92e7-10d4-5c52-a6e0fa16862d

Why?

The ID type is important for different Gremlin server implementations. Neptune is always a string, while the default for Gremlin Server and Janus Graph is a number.

When we implement URL sharing, or other forms of sharing, where the ID must be serialized to a string value we will want a way to determine if the original value was a number or a string.

In order to avoid any potential conflicts with user data string values, this type serialization is being applied judiciously so that it can be assumed to exist.

Next Steps

• Remove Vertex.idType and Edge.idType
• Remove VertexRef and EdgeRef

Validation

• Verified with a smoke test in each query language
• Verified number IDs with JanusGraph
