The query:
string foo = "foo";
IList<T> list = session.CreateCriteria(typeof(T)).
Add(Expression.Eq("Foo", foo).IgnoreCase()).List<T>();

I have a SQLite db that size is over 2.6 GiB. (The db contains maps.)
This db is used by RMaps app. When move the maps to some parts at maximum zoom, the app suddenly closes. However, there is no force close message, no report button. So, I've got an idea that it is caused by reading blocks that are beyond a certain limit e.g. max(int). ...

I've never worked with Mongo in the past, no w...

------ ------ ----- ------

1 axo 2 12
