mitchell852 opened a new issue #3535: DS localizationMethods inconsistent ordering
URL: https://github.com/apache/trafficcontrol/issues/3535
 
 
   In a CDN snapshot (also referred to as the crconfig), the values found in edgeLocations.cache-group-name.localizationMethods are not consistently ordered. This can cause false snapshot diffs when a cachegroup is updated. For example, on cache group create, this field looks like this:
   
   `localizationMethods: [
   "DEEP_CZ",
   "CZ",
   "GEO"
   ]`
   
   If i update the cachegroup and change the lattitude, for example, but not the localizationMethods, it might look like this now in the crconfig:
   
   `localizationMethods: [
   "GEO",
   "CZ",
   "DEEP_CZ"
   ]`
   
   the order really doesn't matter for Traffic Router but...the inconsistent ordering causes snapshot diffs which may confuse system users.
