- pyarrow.output_stream(source, compression='detect', buffer_size=None)#
Create an Arrow output stream.
Path, buffer, file-like object, …
The source to open for writing.
stroptional, 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”).
If None or 0, no buffering will happen. Otherwise the size of the temporary write buffer.
