[Python] Pyarrow IPC guide is missing sink.close()

[asfimport]

In the document: https://arrow.apache.org/docs/python/ipc.html

writer.close() is stated but sink.close() is not. In trying to apply the documentation using compression I got

OSError: Truncated compressed stream

After including sink.close() the problem was resolved.
