cloudsqladmin 保持 CloudSQL 实例始终开启？

Question

My PostgreSQL instance of Google CLoudSQL is somehow kept always on (according to the expense reports). Naturally, I want it turn off when it's not needed to reduce the charges.

I see that it always has 4 connections from cloudsqladmin:

And those connections generate something like a heartbeat at 2.5 requests per second, way more than my own services:

Point-in-time recovery is turned off in the settings.

Is this normal? How can I correct this?

Answer 1

Cloud SQL, much like VM's provided by Compute Engine, are managed infrastructure. A Cloud SQL instance doesn't shut off unless you tell it to shut it off .

The 4 connections marked as "sqladmin" are used by the Cloud SQL service to perform administration tasks and monitoring. They are using minimal resources, but are used for things like creating a database via the API (or GUI) or generating the graphs you are looking at.
