pub struct ArrowWriterOptions {
    properties: WriterProperties,
    skip_arrow_metadata: bool,
    schema_root: Option<String>,
    schema_descr: Option<SchemaDescriptor>,
}

See ArrowWriter for how to configure the writer.

Fields

properties: WriterProperties

skip_arrow_metadata: bool

schema_root: Option<String>

schema_descr: Option<SchemaDescriptor>

Implementations

impl ArrowWriterOptions

pub fn new() -> Self

Creates a new ArrowWriterOptions with the default settings.

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

Sets the WriterProperties for writing parquet files.

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.

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

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

pub fn with_parquet_schema(self, schema_descr: SchemaDescriptor) -> Self

Explicitly specify the Parquet schema to be used

If omitted (the default), the ArrowSchemaConverter is used to compute the Parquet SchemaDescriptor. This may be used When the SchemaDescriptor is already known or must be calculated using custom logic.
