Add CSOM API to choose content database and quota when creating site collections
In the April 2014 Cumulative Update for SharePoint 2013 (released on 7th of May 2014) you published the possibility to create site collections remotely via the CSOM API.
Till today it's not possible to choose a desired content database where the site collection should be stored in or to configure a quota template.
Senior Program Manager Vesa Juvonen from Microsoft wrote a detailed blog article about this topic and received a broad response from the community where many people need these missing features.
Thanks for your feedback! Although we appreciate your time and effort to give us this feedback, it’s not something we’re planning to do right now.
We are not planning to invest on the on-premises specific CSOM operations.
