pyarrow.output_stream(source, compression='detect', buffer_size=None)

Create an Arrow output stream.

  • source (str, Path, buffer, file-like object, ..) – The source to open for writing.

  • compression (str optional, default 'detect') – The compression algorithm to use for on-the-fly compression. If “detect” and source is a file path, then compression will be chosen based on the file extension. If None, no compression will be applied. Otherwise, a well-known algorithm name must be supplied (e.g. “gzip”).

  • buffer_size (int, default None) – If None or 0, no buffering will happen. Otherwise the size of the temporary write buffer.
