Red Hat Satellite to Drop MongoDB and Standardize on PostgreSQL Database
Red Hat Satellite uses two databases today – MongoDB and PostgreSQL. MongoDB is embedded in currently supported versions of Satellite 6 and was first introduced in Satellite 6.0 (i.e. Red Hat Satellite Product Lifecycle). This database change is a still to come, but the product team wanted to go ahead and communicate this intent to our users so they were not caught by surprise as this is a change to the underlying databases of Satellite.
