> Extension for sketch-based statistics

> Key: BEAM-2728
> URL: https://issues.apache.org/jira/browse/BEAM-2728
> Project: Beam
> Issue Type: New Feature
> Components: sdk-java-extensions

> Goal : Provide an extension library to compute approximate statistics on
> streams.
> Interest : Probabilistic data structures can create an approximation (sketch)
> of the current state of a stream without storing every element but rather
> processing each observation quickly to summarize its current state and find
> useful statistical insights.
> Implementation is here :
