It is too good to watch . <| sep |> Question , when you purchase the game do you get a serial key or do you have to make an account ? <| sep |> Yes , the transaction log is basically a differential between the last full backup and the current database state . There may be some additional mechanisms that flush data from the transaction log to the database file , but the transaction log isn ' t truncated until you do a full db backup . It ' s not large amounts of data because it ' s stored as a differential . It ' s the same way that git can reproduce the history of hundreds of files without taking up a huge amount of space . Also keep in mind that most of the time the db server tries to keep all the actively used data in memory instead of having to read it from disk . When it doesn ' t have the data it needs in memory , it has to go to the disk which is much much slower
