MongoDB is a source-available cross-platform document-oriented database program for high-volume storage. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas.
Deleting a database cluster permanently and irreversibly destroys the cluster, its contents, and its automated backups.
To destroy a database cluster from the control panel, open the cluster’s More menu. Click Destroy to go to the cluster’s Settings page.
In the Destroy this database cluster section at the bottom of the page, click the Destroy button. This opens a Destroy database cluster confirmation window.
To permanently destroy the cluster, type or copy and paste the name of the database cluster into the text field, then click Destroy.
