| Class | Description |
|---|---|
| ApproximateCountDistinct |
PTransforms for estimating the number of distinct elements in a PCollection, or
the number of distinct values associated with each key in a PCollection of KVs. |
| ApproximateCountDistinct.Globally<T> |
PTransform for estimating the number of distinct elements in a PCollection. |
| ApproximateCountDistinct.Globally.Builder<T> | |
| ApproximateCountDistinct.PerKey<K,V> | |
| ApproximateCountDistinct.PerKey.Builder<K,V> | |
| HllCount |
PTransforms to compute HyperLogLogPlusPlus (HLL++) sketches on data streams based on the
ZetaSketch implementation. |
| HllCount.Extract |
Provides
PTransforms to extract the estimated count of distinct elements (as Longs) from each HLL++ sketch. |
| HllCount.Init |
Provides
PTransforms to aggregate inputs into HLL++ sketches. |
| HllCount.Init.Builder<InputT> |
Builder for the
HllCount.Init combining PTransform. |
| HllCount.MergePartial |
Provides
PTransforms to merge HLL++ sketches into a new sketch. |
