Quack: DuckDB 클라이언트-서버 프로토콜

Quack introduces a new HTTP-based client-server protocol that extends DuckDB beyond its traditional in-process architecture, enabling multiple concurrent writers to access the same database from different processes or machines. This capability transforms DuckDB from a single-process solution into a viable platform for distributed analytics workloads while preserving its renowned performance and ease of use. With production release planned for DuckDB v2.0, Quack significantly expands DuckDB's potential as a general-purpose data processing tool.
