In the JDBC driver for Flight SQL, the driver will transmit unrecognized options on the connection URI as CallHeaders: https://github.com/apache/arrow/blob/2f627c213fc328ca7cd058d4455581fc246837da/java/flight/flight-sql-jdbc-driver/src/main/java/org/apache/arrow/driver/jdbc/utils/ArrowFlightConnectionConfigImpl.java#L152
The ODBC driver has the same behavior. It would be good if this were documented formally as a standard way of sending and receiving data source-specific connection information in FlightSQL sources. The PR for easily sending/receiving headers was written with this purpose in mind (https://github.com/apache/arrow/pull/8572 ) Does the ADBC driver for Flight SQL also do this? -- *James Duong* Lead Software Developer Bit Quill Technologies Inc.
