At the day job, I have been working on adding iceberg catalog and "write" support to duckdb's iceberg extension. These new features make it possible to use duckdb as a sql engine to query and manipulate your data in your data lake for free! Well on your own compute

It will get merged into the official extension but not sure on the timeline. In the meantime feel free to take a look and play with it. I also created a slack channel I can add anyone interested in keeping track more closely add/or providing feedback. Just DM me
