This is just an example I have used to explain what should be the best way to generate
Next-LSN.
The overall aim for this feature is to start the database with as much accuracy as possible after database corruption
occurreddue to missing files or hardware crash.
However it is not possible to start with full consistency and accuracy after such a

Just so I understand correctly, the aim of this is to "fix" the
situation where out of the thousands of files and 100s of GB of data
