+Size Limitations
+----------------
+
+Data and string properties cannot hold more than 16MB. To store
+larger amounts of data, either:
+
+- Break the data into 16MB chunks, or
+- Store data directly on the file system and store paths to the files in the {+realm+}.
+
+{+service-short+} throws a runtime exception if your app attempts to
+store more than 16MB in a single property.
+
+To avoid size limitations and a performance impact, it is best not to
+store large blobs, such as image and video files, directly in a
+{+realm+}. Instead, save the file to a file store and keep only the
+location of the file and any relevant metadata in the {+realm+}.
