distinctCountRawHllPlus

This section contains reference documentation for the DISTINCTCOUNTRAWHLLPLUS function.

Returns HLLPlus response serialized as string. The serialized HLLPlus can be converted back into an HLLPlus and then aggregated with other HLLPluses. A common use case may be to merge HLLPlus responses from different Pinot tables, or to allow aggregation after client-side batching. The optional parameter p defines the normal set precision and the parameter sp defines the sparse set precision.

Signature

DISTINCTCOUNTRAWHLLPLUS(colName) DISTINCTCOUNTRAWHLLPLUS(colName, p) DISTINCTCOUNTRAWHLLPLUS(colName, p, sp)
