## Replication

You can add up to 2 replicas to an existing MySQL database on Clever Cloud to enhance performance and reliability. They're set up as read-only replicas with full physical replication, in a different availability zone (AZ) or region if requested.

On MySQL replication is binlog-based, so it's a logical and not a physical replication. Maybe we can mention that replication is available starting with MySQL 5.7.


You can see if a database is a primary server or a replica from the MySQL dashboard in [the Console](https://console.clever-cloud.com). If a primary server isn't available, a replica can be promoted as a standalone server and linked to applications. Promotion isn't yet self-service: contact [Clever Cloud support](https://console.clever-cloud.com/ticket-center-choice) to perform it.

Did you check this? AFAIK, it's the case for PostgreSQL, not sure for MySQL


> [!Note] Replication setup isn't yet available from API or the Console

Mention of Promotion/Replication not available in Console is redundant, merge it in a single note.
