Extend the external data source framework with a request/response Connector SPI for services that return data over a network protocol. Implement the first connector for Apache Arrow Flight over gRPC. - ConnectorFactory/Connector/ResultCursor: new SPI interfaces for connection-oriented external sources - AsyncConnectorSourceOperatorFactory: async operator that drains a connector on a background thread with backpressure - OperatorFactoryRegistry: dispatches ConnectorFactory via the ExternalSourceFactory hierarchy - FlightConnectorFactory/FlightConnector: Arrow Flight implementation with schema resolution and streaming result cursor - FlightTypeMapping: Arrow-to-ESQL type conversion - GrpcDataSourcePlugin: plugin wiring via ServiceLoader - EmployeeFlightServer: in-memory test fixture serving employee data - FlightFormatSpecIT: integration tests via csv-spec against a live Flight server - ExternalSourceDrainUtils: shared drain loop with timeout - entitlement-policy.yaml: grants manage_threads and outbound_network Developed using AI-assisted tooling
