count(distinct(dimension)) cannot translate to hyperUnique
SharpRay opened this issue · comments
I created a batch ingestion spec and defined a hyperUnique metric in it. When I query data from dataSource using sparkline, I found the count(distinct(dimension)) cannot translate to hyperUnique aggregation. Is it a bug or the misuse I made? or this feature is not supported for now?
The druid cardinality aggregator is not supported too, as supplementary.
We haven't added support for cardinality or HyperUnique aggregator.
We should be adding support for it soon.
Thanks
