Fabian Hueske commented on FLINK-10993:
---------------------------------------

Thanks for your offer to help with this effort [~yanghua].

I think before we start picking up this issue (or FLINK-8601) again, we need to 
find a committer who agrees to work on this.
This is not a small feature and will require a considerable amount of time. 
Without committer commitment to shepherd the feature, working on a new PR (or 
updating the existing PR for FLINK-8601) is very likely lost effort.
This is especially important if the scope of the feature has not been 
thoroughly discussed before.

> Bring bloomfilter as a public API

> Flink internally provides an implementation of BloomFilter, but only for 
> internal optimization, and does not provide APIs for public access.
> Here is a user mail discussion before : 
> http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Bloom-filter-in-Flink-td10608.html
> Considering that many users have the need to "determine duplicates" in 
> streaming computing, I think it would make sense to provide such an API.
> In addition, Spark has provided BloomFilter as a public API : 
> {code:java}
> val bf = df.stat.bloomFilter("dd",dataLen,0.01)
> val rightNum = rdd.map(x=>(x.toInt,bf.mightContainString(x)))
> {code}
