@josh_wills - Have you given any thought to creating a tap for DuckDB? I'm using DuckDB in my workflow because it provides me efficient temp storage (4GB of .csv files in 600KB) and loading the .csvs is much faster than pandas` read_csv(). Since Metabase is not yet ready to consume the DuckDB database directly, I'm pushing my data into Postgres for reporting. I'm working around not having the DuckDB tap by just pushing the data to Postgres with pandas right now, and it's working fine, but I'm curious if the tap is something you're already considering.
