@@ -105,6 +105,11 @@ An important point is that if the input source supports
zero-copy reads
(e.g. like a memory map, or ``pyarrow.BufferReader``), then the returned
batches are also zero-copy and do not allocate any new memory on read.
+All stream objects have a ``close`` method. In the above example
+:func:`~pyarrow.BufferOutputStream.getvalue` both closes and returns the
buffer.
+If the return object is not needed, call the relevent ``close`` method
+after you are finished using the object to avoid data corruption issues.
Review comment:
Also mention that the context protocol should work as well (i.e. the
`with` statement).
