As I change dremio connection from JDBC to Arrow Flight. Official dremio said the performance of Arrow Flight is faster 100x-1000x than JDBC or ODBC.
Actually, According to my testing. Arrow Flight and JDBC have similar performance. You can refer to below info. I think that the testing result is not reasonable as it is far different from official dremio. Could anyone help me. Maybe there are some issues over my side but I have not found.
