+The estimated target disk throughput. This value is only applied if
+``should_stream`` is set to ``true``.This value can be specified using
+the same semantics as ``target_throughput``, that is either as the
+number of bytes per second as an integer, or using a rate suffix.

+---------
+.. note::
+   This configuration option is only supported when the ``preferred_transfer_client``

+
+.. note::
+   This configuration option is only supported on Linux.
+
+**Default** - ``false``
+
+If set to ``true``, the CRT client will enable direct IO to bypass the OS
+cache when sending PUT requests. Enabling direct IO may be useful in cases
+where the disk IO outperforms the kernel cache.
