This section contains reference documentation for the DISTINCTCOUNTRAWHLL 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.
DISTINCTCOUNTRAWHLL(colName, log2m)
These examples are based on the Batch Quick Start.
