rob05c opened a new pull request #2249: Add CRConfig DS Modified fields
URL: https://github.com/apache/incubator-trafficcontrol/pull/2249
 
 
   Adds a "modified" field to the CRConfig deliveryServices objects,
   indicating the last time that DS's database table row was modified.
   
   Adds a "anyModified" field to the CRConfig deliveryServices objects,
   indicating the last time any database field used to create the JSON
   object was modified, also including the server assignments (which
   are in the contentServers key, not the deliveryServices key)
   
   Adds a "version" field to the CRConfig object, indicating the API
   version used to create that CRConfig.
   
   Adds database triggers updating the deliveryservices last_modified
   timestamp when a ds_regex, ds_server, or staticdnsentry is deleted.
   
   These features are being added, with the goal of making it possible
   for Traffic Router to determine if any individual DS in the CRConfig
   has been modified, and only reload modified DSes, not everything.
