+Batching Modifications
+######################
+
+A :class:`~google.cloud.spanner.batch.Batch` represents a set of data
+modification operations to be performed on tables in a dataset.  Use of a
+``Batch`` does not require creating an explicit
+:class:`~google.cloud.spanner.snapshot.Snapshot` or
+:class:`~google.cloud.spanner.transaction.Transaction`.  Until
+:meth:`~google.cloud.spanner.batch.Batch.commit` is called on a ``Batch``,
+no changes are propagated to the back-end.
+
+
+Starting a Batch
+----------------
+
+.. code:: python
+
+    batch = session.batch()
+
+
+Inserting records using a Batch
+-------------------------------
+
+:meth:`Batch.insert` adds one or more new records to a table.  Fails if
+any of the records already exists.
+
+.. code:: python
+
+    batch.insert(
+        'citizens', columns=['email', 'first_name', 'last_name', 'age'],
+        values=[
+            ['[email protected]', 'Phred', 'Phlyntstone', 32],
+            ['[email protected]', 'Bharney', 'Rhubble', 31],
+        ])
+
+.. note::
+
+    Ensure that data being sent for ``STRING`` columns uses a text string
+    (``str`` in Python 3; ``unicode`` in Python 2).
+
+    Additionally, if you are writing data intended for a ``BYTES`` column, you
+    must base64 encode it.
+
+
+Update records using a Batch
+-------------------------------
+
+:meth:`Batch.update` updates one or more existing records in a table.  Fails
+if any of the records does not already exist.
+
+.. code:: python
+
+    batch.update(
+        'citizens', columns=['email', 'age'],
+        values=[
+            ['[email protected]', 33],
+            ['[email protected]', 32],
+        ])
+
+.. note::
+
+    Ensure that data being sent for ``STRING`` columns uses a text string
+    (``str`` in Python 3; ``unicode`` in Python 2).
+
+    Additionally, if you are writing data intended for a ``BYTES`` column, you
+    must base64 encode it.
+
+
+Insert or update records using a Batch
+--------------------------------------
+
+:meth:`Batch.insert_or_update` inserts *or* updates one or more records in a
+table.  Existing rows have values for the supplied columns overwritten;  other
+column values are preserved.
+
+.. code:: python
+
+    batch.insert_or_update(
+        'citizens', columns=['email', 'first_name', 'last_name', 'age'],
+        values=[
+            ['[email protected]', 'Phred', 'Phlyntstone', 31],
+            ['[email protected]', 'Wylma', 'Phlyntstone', 29],
+        ])
+
+.. note::
+
+    Ensure that data being sent for ``STRING`` columns uses a text string
+    (``str`` in Python 3; ``unicode`` in Python 2).
+
+    Additionally, if you are writing data intended for a ``BYTES`` column, you
+    must base64 encode it.
+
+
+Replace records using a Batch
+-----------------------------
+
+:meth:`Batch.replace` inserts *or* updates one or more records in a
+table.  Existing rows have values for the supplied columns overwritten;  other
+column values are set to null.
+
+.. code:: python
+
+    batch.replace(
+        'citizens', columns=['email', 'first_name', 'last_name', 'age'],
+        values=[
+            ['[email protected]', 'Bharney', 'Rhubble', 30],
+            ['[email protected]', 'Bhettye', 'Rhubble', 30],
+        ])
+
+.. note::
+
+    Ensure that data being sent for ``STRING`` columns uses a text string
+    (``str`` in Python 3; ``unicode`` in Python 2).
+
+    Additionally, if you are writing data intended for a ``BYTES`` column, you
+    must base64 encode it.
+
+
+Delete records using a Batch
+----------------------------
+
+:meth:`Batch.delete` removes one or more records from a table.  Non-existent
+rows do not cause errors.
+
+.. code:: python
+
+    batch.delete('citizens',
+        keyset['[email protected]', '[email protected]'])
+
+
+Commit changes for a Batch
+--------------------------
+
+After describing the modifications to be made to table data via the
+:meth:`Batch.insert`, :meth:`Batch.update`, :meth:`Batch.insert_or_update`,
+:meth:`Batch.replace`, and :meth:`Batch.delete` methods above, send them to
+the back-end by calling :meth:`Batch.commit`, which makes the ``Commit``
+API call.
+
+.. code:: python
+
+    batch.commit()
+
+
+Use a Batch as a Context Manager
+--------------------------------
+
+Rather than calling :meth:`Batch.commit` manually, you can use the
+:class:`Batch` instance as a context manager, and have it called automatically
+if the ``with`` block exits without raising an exception.
+
+.. code:: python
+
+    with session.batch() as batch:
+
+        batch.insert(
+            'citizens', columns=['email', 'first_name', 'last_name', 'age'],
+            values=[
+                ['[email protected]', 'Phred', 'Phlyntstone', 32],
+                ['[email protected]', 'Bharney', 'Rhubble', 31],
+            ])
+
+        batch.update(
+            'citizens', columns=['email', 'age'],
+            values=[
+                ['[email protected]', 33],
+                ['[email protected]', 32],
+            ])
+
+        ...
+
+        batch.delete('citizens',
+            keyset['[email protected]', '[email protected]'])
