I'm actually not a fan of dbx. I prefer the AWS Glue interactive sessions way of using the IDE. It's exactly like the web notebook experience. I can see the reason why dbx exists, but I'd still like to use a regular notebook experience in my IDE.

Looks like it is because the oauth2client.service_account does not know about DBFS (whereas spark does).Is it an option to manage your secrets in databricks? https://docs.databricks.com/security/secrets/secrets.html

Hi, it is related to partitioning optimization. By default, the JDBC driver queries the source database with only a single thread. So write was from one partition as one partition was created, so it was using a single core. When you used pandas, it d...
