How does a trek to K2 base camp in the Himalayas spark the idea for a database company? In Episode 27 of Talking Postgres with Claire Giordano, guest Peter Farkas—CEO and co-founder of FerretDB—shares the origin story of this open source MongoDB alternative. (Spoiler: “Ferret” wasn’t the original name). We dig into why Postgres was the obvious choice, what “true open source” means to Peter, and how FerretDB is now powered by the open source DocumentDB extension from Microsoft. Plus, why Hungarian Trappist cheese might deserve a footnote in database history.
