Hi there... Configuration autotuning is something I am really
interested in.
I have seen this page: http://wiki.postgresql.org/wiki/
GUCS_Overhaul and
a couple of emails mentioning this, so I wanted to ask is someone
already
on it? If yes, I'd like to contribute.
Good time to give a status report on what's been going on with all
this.
With some help I just finished off an answer to problem #1 there
recently, "Most people have no idea how to set these". There was
some concern here that work was being done on config tools without a
clear vision of what was going to be tuned. See http://wiki.postgresql.org/wiki/Tuning_Your_PostgreSQL_Server
for an intro on how to set the 18 most important parameters (+7
logging parameters) based on the best information I'm aware of.
Circa June, Steve Atkins was looking into writing a C++/Qt GUI
tuning interface application, with the idea that somebody else would
figure out the actual smarts to the tuning effort. Don't know where
that's at.
First pass is done. Needs a little cleanup before sharing. I spent a
fair while down OS-specific-hardware-queries rathole, but I'm better
now.
Cheers,
Steve
