Hey team, I am evaluating Cerbos. For production environment, do you recommend using S3 or RDS Postgres?

Hi @Petra Barus, thanks for your consideration. If your application is going to make dynamic changes to the policies, we recommend a database back end. However, if you think the policies are doing to stay relatively static, then a disk or git based is recommended.

So I am building a digital content e-commerce. When a customer purchase a content, the system will publish the permission to that person. I think that’s considered pretty dynamic, right?

Yes. If you are constantly changing policies based on events like customer purchases, then using a database is probably easier than writing to S3.

@Charith (Cerbos) thanks a lot for the answer. How often does the polling happens? Is it configurable? Can we trigger it?

You can configure the polling interval: https://docs.cerbos.dev/cerbos/latest/configuration/storage.html#blob-driver (

updatePollInterval

). You can also trigger a reload using the Admin API: https://docs.cerbos.dev/cerbos/latest/api/admin_api.html#_reload_store
