s-a-p··on Claude Opus 4.8

s-a-p··on Why DuckDB is my first choice for data processing
"making DuckDB potentially a suitable replacement for lakehouse formats such as Iceberg or Delta lake for medium scale data" > I'm a Data Engineering noob, but DuckDB alone doesn't do metadata & catalog management, which is why they've also introduce DuckLake.

Related question, curious as to your experience with DuckLake if you've used it. I'm currently setting up s3 + Iceberg + duckDB for my company (startup) and was wondering what to pick between Iceberg and DuckLake.
