> Parquet. But, I'd also like to store PDFs, CSVs, images

yes, you can store all of these in Supabase Storage and it will probably "just work" with the tools that you already use (since most tools are s3-compatible)

Here is an example of one of our Data Engineers querying parquet with DuckDB: https://www.youtube.com/watch?v=diL00ZZ-q50

We're very open to feedback here - if you find any rough edges let us know and we can work on it (github issues are easiest)
