Hello, does anybody know if there is some possibility to not have WAL
file as a normal file on the disk, but only in memory? I understand that
all the modifications to the database would get lost in case of the
application / OS crash, but for my application, I only need the level of
durability
Hello Jens and Warren,
Performance is really one of the reasons, second is concurrent writer
and readers (which can be in fact viewed as part of the performance).

Why turn on WAL mode at all,

as a kind of atomic operation which "merges data in the main database
file and in the WAL". Is that understanding wrong?
Thanks, Pavel

And how do you change location of the WAL file? Plus, will the main
database file really get corrupted (as in Consistency corrupted, not
only Durability of the data which were in the WAL file) if the OS crashes?

Which is, as I mentioned not acceptable. Or, it depends, what is meant
by corruption here. As I mentioned, I can loose D from ACID in between
the checkpoints, I need the other ones.

Hello Dan, so you are saying that if WAL is somehow in memory only
(not properly persisted) and app or OS crashes in the middle of the
checkpoint operation, my main database file will get corrupted? A
prompts you to consider these things? Is sqlite
being too slow for you?
