Databricks ODBC driver tooks long time to list columns

[Youngwb]

I'm testing the performance of databricks, when I use ODBC driver to submit query, I found it slower than notebook,and it looks like odbc driver will send "list columns" request to databricks, 

1. Is there a way to prevent the ODBC driver from sending these requests?

2. Are these requests necessary?
