The short version

  • Each has a real cost: DuckDB client-server setup remains in beta and not recommended for production distributed scenarios; Kubernetes complex initial setup and configuration with multiple interdependent components
  • They diverge on capability: DuckDB covers In-process Execution, Kubernetes covers Container orchestration.
