I want to output multiple lists of unique column values with KQL. For instance for the following table: A B C 1 x one 1 x two 1 y one I want to output K V A [1] B [x,y] C [one, two] INote. A distance function doesn't behave like equality (that is, when both dist(x,y) and dist(y,z) are true it doesn't follow that dist(x,z) is also true.)Is there any way in KQL we can combine values (count) from different queries into a single query.

Materialized views always return an up-to-date result of the aggregation query (always fresh).
