Summary
Nonevalues to Arrow arrays.PyArrow infers
[None]as Arrow'snulltype. Flight SQL prepared statements provide an expected bind parameter schema, so sending that inferred type can make the parameter batch differ from the schema the server prepared.The client now builds null arrays with the prepared field type when that type is known. It keeps inference for non-null values and for named parameters absent from the prepared schema, preserving the existing permissive behavior.
