Does Ruby on Rails' ActiveRecord support "disconnected recordsets" (like ADO.net)?

Question

Using Microsoft's ADO.net, one can you query database -> disconnect database connection -> query/manipulate locally -> connect again (re-synchronize local with database).

I've found value in this as overall it can minimize database hits.

Does ActiveRecord support such a model/pattern?

Answer 1

Minimizing database hits can be handled without closing database connections.

Database connections are expensive resources, opening and closing them will slow your app down.
