From here, mv-expand does its thing, and converts each item in the JSON array into individual row. It uses the same name as the original column for the new on, Computers. As you can see, mv-expand can be very useful for transforming JSON columns into easily usable rows. See Also The...
In Real-Time Intelligence your data typically flows through Eventstream and then lands in an Evenhouse hosted KQL Database where it is stored in a table. An Eventhouse can have 1 to many databases. A database can have one to many tables. And a table has columns to store your data. Th...

We will be returned an array with our string split out. Split is index aware so if your data is in the same order, you can split directly into new columns. letExampleText=datatable(TestData:string) ['Name=Reprise99,UPNSuffix=testdomain.com,AadTenantId=345c1234-a833-43e4-1d34-123440...
