+Change Streams

+
+As of version 3.6 of the MongoDB server, a new ``$changeStream`` pipeline stage is supported in the aggregation
+framework. The Ruby driver provides an API for receiving notifications for changes to a particular collection using this
+new pipeline stage. Although you can create a change stream using the pipeline operator and aggregation framework
+directly, it is recommended to use the driver API described below as the driver resumes the change stream if there is
+timeout or network error.
+
+Change streams on the server requires a ``"majority"`` read concern or no read concern.
+
+Change streams do not work properly with JRuby because of the issue documented here_.
+
+.. _here: https://github.com/jruby/jruby/issues/4212
+
+Namely, JRuby eagerly evaluates ```#next`` on an Enumerator in a background green thread.
+So calling ```#next`` on the change stream will cause getmores to be called in a loop in the background.
+
+Watching for changes on a particular collection
+-----------------------------------------------
+
+A change stream is created by calling the ``#watch`` method on a collection:
+
+.. code-block:: ruby
+
+  stream = collection.watch
+  collection.insert_one(a: 1)
+  doc = stream.to_enum.next
+  process(doc)
+
+
+You can also receive the notifications as they are available:
+
+.. code-block:: ruby
+
+  stream = client[:test].watch
+  enum = stream.to_enum
+  while doc = enum.next
+    process(doc)
+  end
+
+
+The change stream can take filters in the aggregation framework pipeline operator format:
+
+.. code-block:: ruby
+
+  stream = collection.watch([{'$match' => { 'operationType' => {'$in' => ['insert', 'replace'] } } },
+                             {'$match' => { 'fullDocument.n' => { '$gte' => 1 } } }
+                            ])
+  enum = stream.to_enum
+  while doc = enum.next
+    process(doc)
+  end
+
+Close a Change Stream
+---------------------
+
+You can close a Change Stream by calling the ``#close`` method:
+
+.. code-block:: ruby
+
+  stream = collection.watch
+  collection.insert_one(a: 1)
+  doc = stream.to_enum.next
+  process(doc)
+  stream.close

+Creating and using Sessions
+============================

+.. contents:: On this page
+   :local:

+
+
+Version 3.6 of the server introduces the concept of logical sessions for clients.
+A session is an abstract concept that represents a set of sequential operations executed
+by an application that are related in some way. A session object can be create via a ``Mongo::Client``
+and passed to operation methods that should be executed in the context of that session.
+
+Please note that sessions are not thread safe. They can only be used by one thread at a time.
+
+Creating a session from a ``Mongo::Client``
+-------------------------------------------
+
+A session can be created by calling the ``start_session`` method on a client:
+
+.. code-block:: ruby
+
+  session = client.start_session
+
+
+It is valid to call ``start_session`` with no options set. This will result in a
+session that has no effect on the operations performed in the context of that session,
+other than to include a session ID in commands sent to the server. Please see the API docs for all supported
+session options.
+
+An error will be thrown if the driver is connected to a deployment that does not support sessions and the
+``start_session`` method is called.
+
+Note that server sessions are discarded server-side if not used for a certain period of time. That said,
+be aware that if the application calls ``#start_session`` on a client and waits more than 1 minute to use
+the session, it risks getting errors due to the session going stale before it is used.
+
+
+Using a session
+---------------
+A session object can be passed to most driver methods so that the operation can be executed in the
+context of that session. Please see the API docs for which methods support a session argument.
+
+Create a session and execute an insert, then a find using that session:
+
+.. code-block:: ruby
+
+  session = client.start_session
+  client[:artists].insert_one({ :name => 'FKA Twigs' }, session: session)
+  client[:artists].find({ :name => 'FKA Twigs' }, limit: 1, session: session).first
+
+If you like to call methods on a ``Mongo::Collection::View`` in the context of a particular session, you can create the
+``Mongo::Collection::View`` with the session and then call methods on it:
+
+.. code-block:: ruby
+
+  session = client.start_session(causal_consistency: true)
+  view = client[:artists].find({ :name => 'FKA Twigs' }, session: session)
+  view.count # will use the session
+
+You can also pass the session option to the methods directly. This session will override any session associated with
+the ``Mongo::Collection::View``:
+
+.. code-block:: ruby
+
+  session = client.start_session
+  second_session = client.start_session
+  view = client[:artists].find({ :name => 'FKA Twigs' }, session: session)
+  view.count(session: second_session) # will use the second_session
+
+Causal Consistency
+------------------
+A causally consistent session will let you read your writes and guarantee monotonically increasing
+reads from secondaries.
+To create a causally consistent session, set the ``causal_consistency`` option to true:
+
+.. code-block:: ruby
+
+  session = client.start_session(causal_consistency: true)
+
+  # The update message goes to the primary.
+  collection = client[:artists]
+  collection.update_one({ '_id' => 1 }, { '$set' => { 'x' => 0 } }, session: session)
+
+  # Read your write, even when reading from a secondary!
+  collection.find({ '_id' => 1 }, session: session).first
+
+  # This query returns data at least as new as the previous query,
+  # even if it chooses a different secondary.
+  collection.find({ '_id' => 2 }, session: session).first
+
+Since unacknowledged writes don't receive a response from the server (or don't wait for a response), the driver
+has no way of keeping track of where the unacknowledged write is in logical time. Therefore, causally
+consistent reads are not causally consistent with unacknowledged writes.
+
+Note that if you set the causal_consistency option to nil as in ``(causal_consistency: nil)``, it will be interpreted
+as false.
+
+End a session
+-------------
+To end a session, call the ``end_session`` method:
+
+.. code-block:: ruby
+
+  session.end_session
+
+The Ruby driver will then add the id for the corresponding server session to a pool for reuse.
+When a client is closed, the driver will send a command to the server to end all sessions it has cached
+in its server session pool. You may see this command in your logs when a client is closed.
