Component database requirements

Dgraph database requirements
The Dgraph stores the data sets it queries in a set of databases. For high availability, these can be stored on HDFS/MapR-FS or a shared NFS. They can also be stored on the local disk for a non-HA option.

Studio database requirements
Studio requires a relational database to store configuration and state, including component configuration, user permissions, and system settings. If you install with multiple Studio instances, all of them must be connected to the same database.

Workflow Manager Service database requirements
The Workflow Manager Service requires a relational database to store state information.
