Hey, friend 👋

It’s Marcos again, aka “DuckDB News Reporter” with another issue of “This Month in the DuckDB Ecosystem for May 2023.

This has been an exciting month for DuckDB and the whole ecosystem: DuckDB 0.8.0 is out, the project reaches 10k stars on GitHub (well 10,200 stars at the time of writing this), DuckDB now has a Spatial extension, a native Swift API (this is huge) and more.

This simply proves that DuckDB is more alive than ever before, and its stratospheric adoption growth curve keeps looking like a hockey stick.

As always we share here, this is a two-way conversation: if you have any feedback on this newsletter, feel free to send us an email to
