[dna-issues] [JBoss JIRA] Commented: (DNA-40) Create connector to store any content in a relational database

    [ https://jira.jboss.org/jira/browse/DNA-40?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12442883#action_12442883 ] 

Randall Hauch commented on DNA-40:
----------------------------------

Added to the JPA connector support for referential integrity (which is optional).  References that are values in properties are now tracked in the database, where each reference record maps the UUID of the node containing the reference to the UUID of the node being referenced.  Note that this table does not maintain which property contains the reference, which is not required to manage dependencies.

Finally, these references are checked upon closing the BasicRequestProcessor to catch any operations that remove any nodes that are still being referenced by other nodes.

> Create a federation connector that is able to manage information in a relational database using a DNA-defined schema.  This would enable the persistant storage of information that isn't being managed by other connectors.
> Requirements include efficiently storing and accessing large numbers of nodes, large property values (e.g., Binary values), and large numbers of children on nodes.
