Implementations§

Source§

impl ArrowWriterOptions

Source

pub fn new() -> Self

Creates a new ArrowWriterOptions with the default settings.

Source

pub fn with_properties(self, properties: WriterProperties) -> Self

Sets the WriterProperties for writing parquet files.

Source

pub fn with_skip_arrow_metadata(self, skip_arrow_metadata: bool) -> Self

Skip encoding the embedded arrow metadata (defaults to false)

Parquet files generated by the ArrowWriter contain embedded arrow schema by default.

Set skip_arrow_metadata to true, to skip encoding the embedded metadata.

Source

pub fn with_schema_root(self, name: String) -> Self

Set the name of the root parquet schema element (defaults to "arrow_schema")
