Description
The contract of `java.sql.Driver/connect` says that the driver should return null if it realises it's the wrong kind of driver to handle the connection - unfortunately the override in `ArrowFlightJdbcDriver` throws an exception if the scheme isn't arrow-flight or arrow-flight-sql. So, if I'm trying to connect to (e.g.) postgres and the Arrow Flight driver happens to be first in the java.sql.DriverManager's list, I'll get a URL Scheme must be 'arrow-flight'. error.
We could consider a similar pattern to Avatica's UnregisteredDriver/connect, which checks `acceptsURL` first and returns null if appropriate?
(Separately, I suspect that error message should say arrow-flight-sql, given arrow-flight seems to be deprecated?)
Cheers,
James
