LGTM, thanks @tdcmeehan. I mostly just had some questions about auth with the flight server

Thanks @tdcmeehan , LTGM.
Should we add some documentation on how to load up the new ArrowFederationConnector?

LGTM, just a minor clarification to the split scheduling section
RFC-0013-java-connector-federaton.md
Outdated

| #### Split Scheduling Phase | ||
| 1. Coordinator's single-node connector (e.g., JDBC, MongoDB) creates its connector-specific split | ||
| 2. Split is scheduled to C++ worker as `ArrowFederationSplit` containing serialized split bytes |

Just to clarify, the coordinator will send a connector-specific split to the C++ worker, but it will be handled by the ArrowFederation protocol where it will be read as bytes only.

Arrow Flight server that can load Presto Java connectors, and provide a record batch stream from the given connector split. The FlightShim server is designed to work with a native arrow connector, that will use a Flight client to forward the connector split to the server and process the record batch stream. See related PR at prestodb#26404 RFC: prestodb/rfcs#46 Co-authored-by: Pratik Joseph Dabre <pdabre12@gmail.com>
