Hi, I've implemented a test Arrow Flight SQL server which returns different location URIs for the FlightInfo response for CommandPreparedStatementQuery. But the Arrow Flight SQL JDBC Driver seems to ignore the location field and sends DoGet requests to the server that responded for the CommandPreparedStatementQuery.
I've searched the arrow issues and pull requests and found a closed merge request https://github.com/rafael-telles/arrow/pull/42 and a few related issues. It seems that the merge request eventually did not merge, and Arrow Ballista chose to create a proxy mechanism to handle this limitation. (See https://github.com/apache/arrow-ballista/pull/475/files) Looking at the source code of Arrow Flight SQL JDBC Driver - the getStreams method in https://github.com/apache/arrow/blob/main/java/flight/flight-sql-jdbc-driver /src/main/java/org/apache/arrow/driver/jdbc/client/ArrowFlightSqlClientHandl er.java it seems that it is still in an incorrect(?) state. Is there any progress with this issue? Or should I take Arrow Ballista's approach (at least for now)? (Or maybe I just misunderstood something. I'm a newbie to the Arrow ecosystem.) Thank you.
