Configure your advanced configuration

Advanced configuration for Public Cloud Databases engines

Last updated 1st April, 2022


Public cloud database engines are managed services, which means that they are not fully configurable. For example, it is not possible to modify pg_hba.conf.

Advanced configuration is available for the following Public Cloud Databases engines :

  • Cassandra
  • Kafka
  • Kafka Connect
  • MySQL
  • Opensearch
  • PostgreSQL
  • Redis



Please note that changes to the advanced settings apply at the cluster level and therefore to all the databases in the cluster.

Depending on the engine, some settings may already be defined.

Once the advanced configuration has been submitted, it is not possible to reset it to initial values. It is only possible to update the values, so we recommend that you take note of the initial values before changing them.

See the Checking section below

Using the OVHcloud Control Panel

To change the advanced configuration, you first need to log in to your OVHcloud Control Panel and open your Public Cloud project. Click on Databases in the left-hand navigation bar, select your engine instance then the Advanced configuration tab.

Select the key of the advanced setting you want to define, then set its value.

When ready, click on Update advanced configuration.

On the top-right of the advanced configuration tab, you can see the settings which are already defined.
