Hello, I'm a student trying to understand SQLite for my DB project. There are a couple of aspects that I don't quite understand: 1) VDBE. I see how the vdbe stack is created using VDBEAddOp etc. But once the code is generated, I don't see when it's executed. Moreover, is it typical to have an implementation like VDBE in other databases as well? 2) VIRTUAL TABLES. Why should the shared_cache be disabled when using VIRTUAL TABLES?
Thanks Uma
