Thread: Autovacuum Running Timeframe

Autovacuum Running Timeframe

Hello,

I have a problem with autovacuum 

It runs randomly, so when it runs in websites high traffic hours it causes problems with site speed.

Is it possible to define specific timezone when autovacuum process could run?

Regards,

Dimitris

Hi Dimitris,

I would suggest to manually schedule database vacuum using cron jobs, instead of relaying on auto-vacuum.

Are you sure, that's not the recommended use.

I also don't recommend to disable autovacuum why don't you programme a batch task that executes vacuum in  low activity hours

+1

Autovacuum will have far less work to do during peak hours if you
have an off-peak-hours crontab job to run VACUUM ANALYZE.  You
might want to consider doing that at the database level, run using
a database superuser login.
