Specifying StorageType during opening the database is good enough.
Basically we can think a database as transaction group.

I don't see it is necessary to change storage type. Most likely
operation is when storage get low, we will delete not so important
data. onstoragelow event cover pretty much. Another problem is we
actually don't know the size of object we are storing.

Option 3 is very interesting.
