+MongoDB v2.2 has a 16 megabytes limit on document size.
+
+The logic behind the maximum document size is to ensure that the
+document does not require excessive amount of RAM on the machine nor
+excessive amount of bandwidth to return. MongoDB provides the GridFS
+api to handle documents larger than the maximum size. See your specific
+driver api documentation on GridFS.
