Comment:

 Hello

 Looking at the surrounding code, it is indeed quite hairy. Why, if the
 data really lives in cache, did it touch the database in the first place?
 But that's not the point here, I guess.

 I have one question. Is the whole thing wrapped in some kind of
 transaction? If yes, then I believe the code can be merged. If not, then
 this only makes the probability of occurrence smaller ‒ because the
 following code still does expect that if it got there, it can get the data
 from DB and be happy.

 Thanks
