> URL: https://issues.apache.org/jira/browse/DATAFU-101
> Project: DataFu
> Issue Type: Improvement
> Reporter: Matthew Hayes
> Priority: Major
>
> We wrapped HyperLogLogPlus from the stream library:
> https://github.com/addthis/stream-lib/tree/master/src/main/java/com/clearspring/analytics/stream/cardinality
> There are some new classes that look interesting. CountThenEstimate for
> example does an exact count and switches to an estimator once a threshold has
> been reached.
