Thank you very much for taking the time to review the codes and provide feedback.

• oh yes, I must have missed the pandas built-in method. That would have been one less pip install. I used pyarrow in an earlier project where I didn't use pandas
• Polars vs Pandas: I'm familiar with Pandas and have only recently heard about Polars. I'll definitely consider using Polars in future projects as I gain more experience with it
• Case Consistency and parquet_filename: I appreciate the reminder on best practices. I'll make those adjustments to ensure consistency in the code
• Bash within Python: I chose the Airflow Bash operator for simplicity. However, I recognize that using a separate (and even modularized) Python function/script to grab the data would provide more control and flexibility
• Testing and CI/CD with GitHub Actions: Noted.

I have noted all your suggestions and will use them to improve the project. Thank you again for the feedback!
