Description
I am flummoxed by the results of this query always being empty
let requestList = requests | where timestamp >= ago(30m)
| distinct operation_Id;
pageViews | where timestamp >= ago(30m)
| join kind=inner requestList on operation_Id;
Has there been a change recently in the use of operation_Id ?
