Arnaud Fournier created BEAM-2728:
-------------------------------------

             Summary: 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
            Reporter: Arnaud Fournier
            Assignee: Davor Bonaci
            Priority: Minor


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.
