#ParameterExpectationNotes
1Request Frequency
Upgrade to NEW moduleSetTags
3 upgrades  / second → 180 upgrades / minute

The assumption is there are 100 modules in each moduleSet and a moduleSet is available from a dmi plugin within 0.5 seconds. 
Also assume there is a 90% overlap in modules across all CM Handles.
Across 20,000 Nodes there are 10 different ModuleSetTags

2Request Frequency
Upgrade to already existing moduleSetTags
6 upgrades  / second → 360 upgrades / minute

Performance is posted here :  Performance test for updating YANG schema set API

Out-of-scope

  • Upgrade of models for cached data. "ncmp-datastore:operational" is out-of-scope.

Changes agreed between Daniel Hanrahan , Sourabh Sourabh and Toine Siebelink 


ChangeNotes
1No need for ModuleSetTagCachereduce complexity, no significant impact on performance
Can be re-introduced in a better way later if needed but not expected
2Use same method for New and Known Schema Sets (module set tags)
  • NEW SchemaSet → 0 or More NEW YangResources, 1 OR more ModuleReferences
  • KNOWN SchemaSet → 0 NEW YangResources, 1 OR more ModuleReferences

Planning:

  • Allow for 2 more user stories each may take 1 week. 
  • Estimated date of completion is   based on 1 person working. There is a possibility that 1 more person will join in between for implementation but there is no clear visibility on when the person can start contributing as of now. 
  • These are estimates and should not be interpreted as commitments.
