问题
I have just managed to do this basic installation including the Batcache and the Gapp engine plugin for wordpress on Google cloud using Cloud SQL. I just saw that the total usage is 42 hours of the Cloud SQL instance.
My site has no posts and is fairly new. There are no followers neither visitors. I am wondering why the SQL is always on ? I have it to activate only when requested rather than always on.
Thoughts ?

If you set it to on demand it will only connect when its needed. After a few minutes it will shut down again. There will be a spool up time for the first person but it should be very short.
