If somebopdy wants WAL effectively turned off, then can symlink WAL to a
ramdisk that has a GB under the carpet. That would offer all the "benefits" of
WAL being tunred off.
Why this new provision? Is it really that difficult to mount WAL on ramdisk
during reload?
See, we offer non-transaction mode mysql defaults to, already..:-)
Just a thought..
