Description
At the moment, delta-rs is getting the aws region through the environment AWS_REGION. There's no other possibility to specify the region when reading a remote table on s3.
Use Case
The mechanism makes it difficult to read different delta tables on s3 from different AWS regions through the same process. It would be nice to pass this when creating the DeltaTable.
If the `AWS

Connect-Databricks.ps1 uses "https://login.microsoftonline.com" as part of the URI to connect.

I have a simple regression task (using a LightGBMRegressor) where I want to penalize negative predictions more than positive ones. Is there a way to achieve this with the default regression LightGBM objectives (see https://lightgbm.readthedocs.io/en/latest/Parameters.html)? If not, is it somehow possible to define (many example for default LightGBM model) and pass a custom regression objective?
