Data Updates in Azure Data Explorer

Hiram Fleitas updates the data:

I recently ran into a Kustomer that migrated from TSI to ADX (Azure Data Explorer). They were really excited about using Kusto Trender but one item they couldn’t wrap their head around was how to update their hierarchy table(s) in ADX. i.e.  

- Contoso WindFarm Hierarchy (Levels: Plant > Unit > System > Name)
-- Plant
--- Unit
---- System
----- Name 

As a big data platform ADX is an append-only data store, so we don’t have the options to do updates, right? Well, that’s not completely true. We absolutely don’t support updates, but we do have a couple options to simulate updates.

Read on to see what options are available to you.
