Undo and redo operations should also happen in Transaction.
Let’s say we do the redo and for some reason the WAL file is crashed so essentially we performed all the operations which were not even committed and couldn’t do the redo operation because of the file/system/OS (could be anything) crash.
I will have to check the code in R-DBMS how it handles such scenarios 😅
