pyarrow.input_stream

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

Create an Arrow input stream.

Parameters

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

• compression (str 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_size (int, default None) – If None or 0, no buffering will happen. Otherwise the size of the temporary read buffer.
