Use-Case Overview (Sync in watchDog)

Note. Error handling like invalid IDs are handled during the Synchronous part of registration and not part of this use-case overview. 
Upgrade to the same Tag should be captured in synchronous pre-processing.

re-usable methods

1. get modules (delta) from Node (DMI)
2. create schemaset
   1. alt a. combination of exiting Refs and new yang resources
   2. alt b all existing references
3. create anchor
4. update schemaset
   1. alt a. combination of exiting Refs and new yang resources
   2. alt b all existing references

Proposals

Use same methods for NEW and KNOWN Schemasets 

NEW SchemaSet → 0 or More NEW YangResources, 1 OR more ModuleRefernces

KNOWN ScemaSet → 0 NEW YangResources, 1 OR more ModuleReferences

No Cache, reduce complexity, no signifanct impact on perfroamce

void processCreate() {
   if (tagProvided && tag in DB) {
          allModuleRefences = referencesFromDb
          newYangResources = []
       else {
          delta = getDelta()
          newYangResources = delta.newYangResources 
          allModuleRefences = delta.allModuleRefences 
      }
   creatSchemaSet(newYangResources,  allModuleRefences)
   createAnchor()
}       
     
void processUpgrade() {
    if (tagProvided && tag in DB) {
          allModuleRefences = referencesFromDb
          newYangResources = []
       else {
          delta = getDelta()
          newYangResources = delta.newYangResources 
          allModuleRefences = delta.allModuleRefences 
      }
   udpateSchemaSet(newYangResources,  allModuleRefences)
}
