@marmbrus, is this wording okay?

Maybe the following? I tried to justify why its better for ETL, and I hate caching (users are bad at figuring out if their data is going to fit) so I left that part out.
This library is more suited to ETL than interactive queries, since large amounts of data could be extracted to S3 for each query execution. If you plan to perform many queries against the same Redshift tables then we recommend saving the extracted data in a format such as parquet.
