Hi Bryan,

The drive source code is the best documentation that describes the table and row level? detail.

The translator description in the source code sums up the tables an drivers in a succinct way.  If you need any additional clarification, let me know.

Subject: [openstack-dev] [Congress] Info on Currently Supported Data Drivers

Hi, I have a question about where to find the complete set of currently supported data drivers (with table/row details) for Congress. The info at http://congress.readthedocs.org/en/latest/cloudservices.html#drivers<https://urldefense.proofpoint.com/v2/url?u=http-3A__congress.readthedocs.org_en_latest_cloudservices.html-23drivers&d=AwMFAw&c=Sqcl0Ez6M0X8aeM67LKIiDJAXVeAw-YihVMNtXt-uEs&r=djA1lFdIf0--GIJ_8gr44Q&m=DAMyKamIxt_S7FwDt9ft5eTL0Tz_gZ5KyQVueLiVGxA&s=nCnmgLZEB3103MWKkYaVuS4Cnhg8xLNbeoul185--wA&e=> seems to cover only Nova and Neutron.  I'm sure that I can pull this info from the source at https://github.com/stackforge/congress/tree/master/congress/datasources<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_stackforge_congress_tree_master_congress_datasources&d=AwMFAw&c=Sqcl0Ez6M0X8aeM67LKIiDJAXVeAw-YihVMNtXt-uEs&r=djA1lFdIf0--GIJ_8gr44Q&m=DAMyKamIxt_S7FwDt9ft5eTL0Tz_gZ5KyQVueLiVGxA&s=GH2z3O0oq8AZ8EznJOgF7sLtpRrOkDZdWqxQ-X2X6ns&e=> but I was looking for any documentation on the current state of that code's design. The existing blueprints (e.g. at https://github.com/stackforge/congress-specs)<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_stackforge_congress-2Dspecs-29&d=AwMFAw&c=Sqcl0Ez6M0X8aeM67LKIiDJAXVeAw-YihVMNtXt-uEs&r=djA1lFdIf0--GIJ_8gr44Q&m=DAMyKamIxt_S7FwDt9ft5eTL0Tz_gZ5KyQVueLiVGxA&s=0Qe87C5V3-MiQMxtRNs8Cps698pLOve9ee1BRzKskOU&e=> do not go into this detail AFAICT.

Also, since I'm looking into how the current supported Congress tables will support use cases of the OPNFV Copper project [1], it will be also helpful to know where I would look for the set of potential policy-related data items inside OpenStack docs/code for the various components. If I find a gap against a use case, I would want to be able to specify related patches (e.g. where data source driver extensions should get the additional data) so I need to know where the data comes from (and what's available) inside OpenStack.

Thanks for your help!
