Hi Karl Gardner,
Yes, you are correct. The filepath specified in the example BULK 'parquet/taxi/year=2017/month=9/*.parquet'
will only include files from September 2017, not the last three months of 2017.
the description stating "The following sample reads the NYC Yellow Taxi data files for the last three months of 2017" is incorrect.
It should specify that it reads the data for only September 2017.
You can submit a GitHub item for this. Scroll down the page, and you will see the "This page" section. When you click on this, it will take you to the GitHub page and submit a Github item for this issue. The respective product groups will be notified and can correct this.
I hope this answers your question.
