ODAS uses a database to store all its state. By default, this is a local database running on the ODAS cluster itself, but this is not recommended for anything but single-node QuickStart clusters, as state can easily be lost.
You should follow the instructions for creating a suitable database server:
- For AWS, follow the instructions in the RDS Prerequisites section.
- For Azure, follow the instructions in the Azure SQL Prerequisites section.
To configure ODAS to use this database, you can follow the Configuring a Database guide.
