+Efficiently Writing and Reading Arrow Arrays
+--------------------------------------------
+
+Being optimized for zero copy and memory mapped data, Arrow allows to easily
+read and write arrays consuming the minimum amount of resident memory.
+
+When writing and reading raw arrow data, we can use the Arrow File Format
+or the Arrow Streaming Format.
+
+To dump an array to file, you can use the :meth:`~pyarrow.ipc.new_file`
+which will provide a new :class:`~pyarrow.ipc.RecordBatchFileWriter` instance
+that can be used to write batches of data to that file.
+
+For example to write an array of 100M integers, we could write it in 1000
chunks
+of 100000 entries:
