Create site collection in content database

Question

I want to set by default to create a site collection in an independent content database when creating a new site collection automatically!

Ex: each content database only holds one site collection by default!

Is it possible to do that automatically without using code?

Answer 1

I don't think it's possible automatically.

Unfortunately, There is no event receiver triggered when creating/ created a site collection to handle this using event receiver.

However, you can adjust this manually by locking down the content database as the following:

Steps

Before creating a new site collection, you should plan to do the following:

• Lockdown all the web application content databases.

• Create a new independent content database for the new Site Collection.

  

• Create a new Site Collection will be created inside the newly created content database.

Answer 2

Yes, this is possible by overriding the class SPSiteCreationProvider. With this, you can select all of your existing content databases. If you cannot find a content database in the web application that meets the criteria, you could then create a new content database.

You should be aware that this would slow down the site creation process significantly as provisioning a new content database isn't an instant process.
