Thanks so much for this great bug report. I will look to fix these issues and update this when I've resolved it.

I'm hitting this same issue. Any updates?

Unfortunately on Windows you can only use a thread count of 1 at this time.

Amazon Redshift Column Encoding Utility is now deprecated. Instead, please use Redshift's Automatic Table Optimization features through:

ALTER TABLE table_name ALTER SORTKEY AUTO;
ALTER TABLE table_name ALTER DISTSTYLE AUTO;
