Basically, the purpose is to be able to dynamically load yang model, and to be able to interact with them to finally do whatever you want in the SB layer. And there is no possibility as of today to do so in ODL. So this cache mount point allows one to side-load model, and to have them backed by an actual instance of the datastore, without having any device behind (similar as NETCONF, but the device is the datastore). > > Bug Tracking: https://bugs.opendaylight.org/show_bug.cgi?id=7522 > <https://bugs.opendaylight.org/show_bug.cgi?id=7522> > Note: > https://meetings.opendaylight.org/opendaylight-meeting/2017/tws/opendaylight-meeting-tws.2017-01-30-18.01.log.html > > <https://meetings.opendaylight.org/opendaylight-meeting/2017/tws/opendaylight-meeting-tws.2017-01-30-18.01.log.html> > Recording: > https://meetings.webex.com/collabs/#/meetings/detail?uuid=I9FFEQ5TEML679ALSDH6M545W1-9VIB > > <https://meetings.webex.com/collabs/#/meetings/detail?uuid=I9FFEQ5TEML679ALSDH6M545W1-9VIB> >> >> The Conceptual Data Tree stuff does have an API to dynamically create >> prefixed shards.
