Hi Kent,
I was reading the code documentation on your site, and I saw that you
have written this:
"... In the future, the journal will contain a strong checksum of the
data so that the write will complete when the journal entry finishes..."
My question is, is this feature implemented? As far as I can see by
looking at journal.c, you are journaling only the keys and not the data
they point to (it has been issued asynchronously a few steps back to the
SSD, right?).
Also, if this is a feature to be implemented, wouldn't it create more
stress on the CPUs, as well as more latency to issue the IO request to
the SSDs (unless you issue it asynchronously while processing the keylist)?
I'm just curious on how you'd handle it.
Thanks,
Alex
