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

[Randall Hauch (JIRA)]

    [ https://jira.jboss.org/jira/browse/DNA-40?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12443456#action_12443456 ] 

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

Per JSR-283 section 5.1.7, corrected this connector's copy behavior for how "internal" references (from nodes within the subgraph to nodes also within the subgraph) are remapped in the copy, so that the copy's references are also internal to the copy.  Also verified that "outward" references (from nodes within the subgraph to nodes outside of the subgraph) are copied correctly, and that "inward" references (from nodes outside of the original subgraph to nodes in the original subgraph) are not affected by the copy operation (since the original subgraph is not modified).

Note that JSR-170 does not define the semantics of how references are handled in a copy operation.

> 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.
