Delete Active-Active databases
When you delete an Active-Active database (formerly known as CRDB), all instances of the Active-Active database are deleted from all participating clusters.
Because Active-Active databases are made up of instances on multiple participating clusters, to restore a deleted Active-Active database you must create the database again with all of its instances and then restore the data to the database from backup.
We recommended that you:
- Back up your data and test the restore on another database before you delete an Active-Active database.
- Consider flushing the data from the database so that you can keep the Active-Active database configuration and restore the data to it if necessary.
