Struct ParquetWriterBuilder 

pub struct ParquetWriterBuilder { /* private fields */ }

ParquetWriterBuilder is used to builder a ParquetWriter

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.

When writing into an existing Iceberg table, prefer Self::from_table_properties, which derives WriterProperties from the table’s write.parquet.* properties.

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

Create a new ParquetWriterBuilder with custom match mode

pub fn from_table_properties( table_props: &TableProperties, schema: SchemaRef, ) -> Self

Build a ParquetWriterBuilder from Iceberg table properties and a schema, translating write.parquet.* settings into WriterProperties instead of using parquet-rs defaults.

Currently translates the content-defined-chunking keys (write.parquet.content-defined-chunking.*); other keys fall back to parquet-rs defaults.

pub fn with_match_mode(self, match_mode: FieldMatchMode) -> Self

Set the field match mode used to map Arrow fields to Iceberg fields.

Defaults to FieldMatchMode::Id. Use FieldMatchMode::Name when the incoming Arrow schema does not carry Iceberg field-id metadata.
