Description

There could either be

• A global identifier for the entire flight
• Endpoint-specific identifiers

A client could use these unique identifier to perform other kinds of actions. An example would be retrieving logs or statistics about a get – you could see time spent writing the dataset to gRPC or time spent constructing the dataset before handing off to the gRPC write layer
