如何在 LogicApps 中使用 KQL 查询构建嵌套的 HTML 表？

Question

I'm facing an issue with slow performance in this post: Slow performing triple Foreach with Parallelism taking up 40 minutes with LogicApps? , hence thinking of building the solution in a KQL query.

Situation: I have a Foreach Category within a Foreach of Products with a run time of 40 minutes. Basically it builds an HTML table for each Category, and within that category it places the Products together with the right Specialization.

Current setup:

• Foreach Category contains 5 items
  • Foreach Products contains 300 items
    • Foreach Specialization contains 5 items

The results are retrieved from Azure Log Analytics and stored in a LogicApp variable list which can be iterated. How can I build the above solution in to a KQL query?

Answer 1

If I understand the question correctly, you can solve it with one list containing the category, products and specialization, for example:

datatable(Product:string, Category:string, Specialization:string)
[
"p1", "c1", "s1",
"p1", "c2", "s1", 
"p1", "c2", "s2", 
"p1", "c1", "s1",
"p2", "c2", "s1", 
"p2", "c2", "s2"
]
| summarize by Product, Category, Specialization
| order by Product asc, Category asc, Specialization asc 

If the products, categories and specializations are in different tables use the " lookup " operator to join them together and then do the summarization followed by sort.
