Expand description

Arrow writer

Writes Arrow RecordBatches to a Parquet writer

Implementations

impl<W: 'static + ParquetWriter> ArrowWriter<W>[src]

pub fn try_new(
    writer: W,
    arrow_schema: SchemaRef,
    props: Option<WriterProperties>
) -> Result<Self>[src]

Try to create a new Arrow writer

The writer will fail if:

  • a SerializedFileWriter cannot be created from the ParquetWriter
  • the Arrow schema contains unsupported datatypes such as Unions

pub fn write(&mut self, batch: &RecordBatch) -> Result<()>[src]

Write a RecordBatch to writer

NOTE: The writer currently does not support all Arrow data types

pub fn close(&mut self) -> Result<FileMetaData>[src]

Close and finalize the underlying Parquet writer
