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

Create an Arrow input stream.

sourcestr, Path, buffer, file-like object, …

The source to open for reading.

compressionstr optional, default ‘detect’

The compression algorithm to use for on-the-fly decompression. 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_sizeint, default None

If None or 0, no buffering will happen. Otherwise the size of the temporary read buffer.
