> URL: https://issues.apache.org/jira/browse/FLINK-9474
> Project: Flink
> Issue Type: New Feature
> Components: Table API & SQL
> Affects Versions: 1.5.0
> Reporter: Sihua Zhou
> Assignee: Sihua Zhou
> Priority: Major
>
> We can implement an approximate version of "count distinct" base on the
> "Elastic Bloom Filter", It could be very fast because we don't need to query
> the state anymore, its accuracy should could be configurable. e.g 95%, 98%.
