Quack: The DuckDB Client-Server Protocol (opens in new tab)

DuckDB instances can now talk to each other using the Quack remote protocol. This lets you run DuckDB in a client-server setup with multiple concurrent writers. In DuckDB's spirit, Quack is *simple* to set up and builds on proven technologies such as HTTP(S). It's also fast, which allows it to support workloads ranging from bulk operations to small transactions.
