+Inserting and Retrieving RawBSONDocuments
+=========================================

+.. doctest::
+
+  >>> import bson
+  >>> from pymongo import MongoClient
+  >>> from bson.raw_bson import RawBSONDocument
+  >>> client = MongoClient(document_class=RawBSONDocument)
+  >>> client.drop_database("db")
+  >>> client.drop_database("replica_db")
+  >>> db = client.db
+  >>> result = db.test.insert_many(

+  >>> replica_db = client.replica_db
+  >>> for doc in db.test.find():
+  ...     print(f"raw document: {doc.raw}")
+  ...     print(f"decoded document: {bson.decode(doc.raw)}")
+  ...     result = replica_db.test.insert_one(doc)
+  ...
+  raw document: b'...'
+  decoded document: {'_id': 1, 'a': 1}
+  raw document: b'...'
+  decoded document: {'_id': 2, 'b': 1}
+  raw document: b'...'
+  decoded document: {'_id': 3, 'c': 1}
+  raw document: b'...'
+  decoded document: {'_id': 4, 'd': 1}
+
+For use cases like moving documents across different databases or writing binary
+blobs to disk, using raw BSON documents provides better speed and avoids the
+overhead of decoding or encoding BSON.
