Hi , I want to imporve the performance for inserting of huge data in my table . I have only one idex in table .
First question - i want to know the role played by
#fsync = on and #synchronous_commit = on
They are commented by default in 8.4 . When made like this :- fsync = off synchronous_commit = off
It improve the performance :) and query took less time .
I want to understand more in details what exactly had happened one is made them "off" , is it dangerous to do this ? as it will not sync the data in each commit .
