Using R connecting to Dremio via RODBC

Questions
#1

Hi, I have been testing R in exploratory extracting data from Dremio using RODBC. I have notice that even my job have finished in 3mins (Dremio jobs page) but the the wheel still kept spinning in Exploratory. Did I missed anything?

Please advice. Thanks

Do you use built in Dremio Connection for your testing?

Or do you write custom R script to connect to Dremio?
