Hi all,
I have seen the big debat about to have the delay
off or on by default.
Why not enable it by default and introduce a new
parameter to vacuum command itself ? Something like:
VACUUM .... WITH DELAY 100;
It's not just one parameter to tune here. It is a set of parameters that
all together need to be viewed as a whole. The slowdown will be affected
by the other parameters as well, so turning the millisecond knob only is
not even half of the story.
So the other parameter will inserted in the new sintax too, I think is fundamental
the ability of override this values during the vacuum call:
VACUUM .... WITH DELAY 100 [ .... ];
You can do it right now.
set vacuum_cost_delay = 100;
vacuum analyze;
No need to panic.
