- Visualize the queried data using Pandas data frames and Jupyter's table formatting capabilities.
4. Exporting Data to AWS S3
- Copy queried data as Parquet files or CSV files to your AWS S3 storage bucket.
- Partition larger files to manage file sizes effectively, especially considering any file upload limit sizes on your storage plan.
- Explore the stored data in your AWS S3 bucket to ensure successful file exports.
5. Analyzing and Visualizing Data
- Query the stored data in your AWS S3 bucket using DuckDB's read_par function.
- Utilize file globbing to select specific files for querying and analysis.
- Join multiple datasets together for a fully denormalized table view for comprehensive data analysis.
6. Performing Data Analytics
- Use DuckDB to perform lightweight data analytics on your Postgres database data.
- Generate insights such as monthly sales figures, order statuses, and trends using DuckDB's querying capabilities.
- Visualize the analyzed data using data visualization libraries in Python for enhanced insights.
7. Conclusion
- Experiment with different data analytics tools and techniques on your Superbase storage using DuckDB and AWS S3.
- Explore further possibilities for data analysis and visualization to derive meaningful insights from your Postgres database.
By following these steps, you can effectively utilize DuckDB and AWS S3 for file-based Postgres analytics as demonstrated in the video tutorial.
