Hey Tanveer, Something like this should work:
$ python examples/flight/client.py put localhost:1234 foo.csv File Name: foo.csv Table rows= 1 a b 0 1 2 $ python examples/flight/client.py get localhost:1234 -p foo.csv Ticket: <Ticket b"(1, None, (b'foo.csv',))"> <Location b'grpc+tcp://localhost:1234'> a b 0 1 2 Note that Flight itself does not implement SQL query functionality or anything of the sort. It is a common misconception, I think exacerbated since Flight is often discussed in the context of products like Dremio which implement such functionality on top of Flight. But really, Flight itself is just a 'dumb pipe' for Arrow data for building such systems. You may be interested in the FlightSQL proposal which defines at least an interface for database systems to make themselves available over Flight and for clients to generically query them. However that proposal has been stalled for a while.
