Network Infrastructure Solution Kit - Enhancements April 2026

[jim-limprasert-tigergraph]

Enhancements made on Network Infrastructure Solution Kit based on testing done in February 2026.

• Changing the time-related vertices, reducing the layer down from 5 layers to 2 layers - the rationale is that this should provide some good amount of splitting to avoid too many outdegree for a node, while not being too complicated to write a query for
  • Previous: Time_Year -> Time_Date_Month -> Time_Date -> Time_Date_Hour -> Time_Date_Minute -> Event
  • Current: Time_Date -> Time_Date_Minute -> Event
• Removal of unused vertices and edges - if we ever need those, we can add those back later
  • unused vertices: IP
  • unused edges: From_Device, To_Device, Has_Source_IP, Has_Target_IP, Device_Has_IP
  • Files affected:
• Time-related vertices fix: Time_Date and Time_Date_Minute now have STRING primary_id, and a date attribute. This is to avoid the issue around DATETIME primary id, as reported here: https://graphsql.atlassian.net/browse/CORE-4869
• Query changes - change the logic around traversal of time-related vertices
• changes to corresponding meta folder of Network Infrastructure Solution Kit
• changes to readme.md file instruction for the script - updated instructions around getting the meta/schema.json and meta/style.json

New Schema now looks like this:
