[dna-issues] [JBoss JIRA] Resolved: (DNA-281) Connector support for workspaces

[Randall Hauch (JIRA)]

Randall Hauch resolved DNA-281.
-------------------------------

    Resolution: Done


Implemented the changes to support workspaces in connectors.  This involved a lot of changes, including all connectors, the Graph API (and implementation), and all uses of the graph API (including a lot of test cases).

The SimpleRepositorySource that was available in dna-graph/src/java/test was removed because it started to mirror the code that is in the InMemoryRepositorySource (which is now in dna-graph).  This affected quite a few tests cases.

This change also made apparent a couple of issues with the current federation code.  These problems require more in-depth changes and will be done next, but shouldn't be mixed with this set of changes.  This also has implications for several higher-level projects (dna-jcr, getting started examples) that use the connector.  Therefore, these projects were temporarily removed and will be added back in shortly.

> The connector framework doesn't currently have a notion of workspaces.  They were originally designed this way to keep things simple, but it turns out that not having workspaces means that a separate RepositorySource would be needed for each JCR workspace, and even if multiple RepositorySource instances connected to the back end system, a lot of inefficiencies would be introduced (including duplicate connection pools, inability to efficiently handle inter-workspace operations like copying or cloning, difficulty managing sources when creating new workspaces, etc.).
> Therefore, to more closely match the JCR API and to more efficiently support inter-workspace operations (within the same repository), the DNA connector framework should have a notion of workspaces.
