How to retrieve server logs and query progress in Flight SQL

In big data cases(e.g. using Spark SQL to run batch jobs), a SQL may cost dozens of minutes or even hours to complete, how can the client retrieve server logs and progress information using Flight SQL protocol?

Review the Flight SQL protocol and its client and server behavior for long-running Spark SQL jobs. Determine whether server logs and progress information are already exposed, then clarify the expected mechanism and whether the outcome should be an implementation, protocol change, or documentation; no files or tests are named in the issue.
