DISTINCTCOUNTRAWHLLMV
This section contains reference documentation for the DISTINCTCOUNTRAWHLLMV function.
Returns HLL response serialized as string. The serialized HLL can be converted back into an HLL and then aggregated with other HLLs. A common use case may be to merge HLL responses from different Pinot tables, or to allow aggregation after client-side batching.
