vinoyang created FLINK-10993: -------------------------------- Summary: Bring bloomfilter as a public API Key: FLINK-10993 URL: https://issues.apache.org/jira/browse/FLINK-10993 Project: Flink Issue Type: New Feature Components: DataStream API Reporter: vinoyang Assignee: vinoyang
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} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
