Implementations

impl ParquetWriterBuilder

pub fn new(props: WriterProperties, schema: SchemaRef) -> Self

Create a new ParquetWriterBuilder To construct the write result, the schema should contain the PARQUET_FIELD_ID_META_KEY metadata for each field.

pub fn new_with_match_mode( props: WriterProperties, schema: SchemaRef, match_mode: FieldMatchMode, ) -> Self

Create a new ParquetWriterBuilder with custom match mode

pub fn with_arrow_schema(self, arrow_schema: Arc<ArrowSchema>) -> Result<Self>

Set an Arrow schema to use for writing instead of deriving one from the Iceberg schema. The Arrow schema’s structure must match the Iceberg schema (field names, types, nullability), but may contain additional metadata (e.g., Arrow extension types). Returns an error if the schemas don’t match structurally.
