Using External Storage for Large Soup Elements

Some years ago, Mobile SDK implemented external storage to address limitations with storing large JSON strings in the database—for example, a 1-MB cursor window limitation on Android. These limitations no longer exist. Furthermore, recent performance analysis shows that external storage is now slower than internal storage.

Mobile SDK no longer recommends using external storage with SmartStore soups. The external storage feature has been removed in Mobile SDK 11.0.
