Issue

READ queries return outdated data when the synchronous_replication flag is enabled. This causes the slave connection to be disabled, leading to database overload.

Steps to reproduce:

  1. Set MYSQL_USE_SLAVE_CONNECTION to true in the environment variables on Adobe Commerce on cloud infrastructure.

  2. Add the following configuration to .magento.env.yaml to set synchronous_replication to false:

    code language-text 
    DATABASE_CONFIGURATION:
  _merge: true
  slave_connection:
    default:
      synchronous_replication: false

  3. Redeploy and perform frontend actions such as login, add to cart, or place an order.

Expected results:

Slave connection remains enabled when synchronous_replication is set to false.

Actual results:

Slave connection is disabled when synchronous_replication is set to false, causing database overload.
