* background  (colindixon, 17:06:26)
  * Sharon basically says XSQL is trying to provide an easier XSQL
    interface on top of the MD-SAL  (colindixon, 17:06:48)
  * he says that until a month ago, it was very buggy, but there’s been
    a lot of work in the last month to make it more real  (colindixon,
    17:08:28)
  * it basically shows each MD-SAL schema level as an SQL table
    (colindixon, 17:08:58)
  * shows “list vfields nodes/node/table/flow” which shosw shte
    proprties of a flow  (colindixon, 17:09:34)
  * shows “select * from nodes/node;” and gets the list of the nodes
    (colindixon, 17:10:25)
  * shows a simple query builder where you can get control-space
    context-senseitive auto-completion for writing queries which is
    really pretty cool  (colindixon, 17:11:36)
  * dbainbri asks if there is a plan to turn this into a web-based tool
    and release it as part of the normal distribution  (colindixon,
    17:15:11)
  * Sharon says that he couldn’t get it to work the web-based thing and
    the REST RPC call for some reason and so he fell back to making a
    Java/swing app  (colindixon, 17:17:03)

* demo of working with Pentaho Report Designer  (colindixon, 17:17:32)
  * shows how to generate reports including PDF output  (colindixon,
    17:18:24)

* binding aware code  (colindixon, 17:18:42)
  * the big new feature is that you can do an XSQL query and then get
    back the BindingAware java objects directly  (colindixon, 17:19:12)
  * shows ToasterProviderModule in
    org.opendaylight.controller.config.yang.config.toaster_provider.impl
    (colindixon, 17:19:49)
  * you should be able to produce an instance identifier from the
    results to be able to do get where it actually is in the backing
    store  (colindixon, 17:23:22)
  * dbainbri asks if you can also query TSDR, the answers is not right
    now, but it’s doable  (colindixon, 17:25:25)
  * currently when it gets the data, it does full table scans which is
    potentially slow  (colindixon, 17:27:23)
  * Sharon has been thinking about how to construct indices and make
    things faster, Sharon says he could use help here  (colindixon,
    17:28:10)

    (colindixon, 17:31:40)

* forums to get help  (colindixon, 17:32:26)
  * colindixon points out that calls for help sent to controller-dev,
    which is somewhat of a black hole these days  (colindixon, 17:36:52)
  * figuring out how to bring topics up that have broad interest is hard
    and something we’re bad at as a community  (colindixon, 17:39:10)

    discussion  (colindixon, 17:39:21)
