System database for load balancer deployment
Hybrid Data Pipeline requires a system database for storing user and configuration information. When deploying the service behind a load balancer, you must use a supported external database. An external system database ensures that user and configuration information is consistent across multiple nodes behind the load balancer. These nodes use the system information on the external system database to access data and return successful queries. In addition, an external system database provides better security and more flexibility for backing up system information. As a best practice, the external system database should be replicated, or mirrored, to promote the continuous availability of the service. Configuring Hybrid Data Pipeline to use a system database occurs during installation.
