[jira] [Created] (FLINK-12089) Broadcasting Dynamic Configuration

langjingxiang created FLINK-12089:
-------------------------------------

             Summary: Broadcasting Dynamic Configuration
                 Key: FLINK-12089
                 URL: https://issues.apache.org/jira/browse/FLINK-12089
             Project: Flink
          Issue Type: Improvement
          Components: API / Scala, Runtime / Network
    Affects Versions: 1.7.2
            Reporter: langjingxiang


flink Broadcasting Dynamic Configuration now the way is:

datastream :broadcasting stream to join 

dataset: broadcasting dataset 

but Intrusion to user business is relatively large ，

I think we can design an API:

evn.broadcast(confName,confFunction,SchedulingTime)

dataStream.map(new RichMapFunction(){

public void open(Configuration parameters) throws Exception {
Objec broadcastSet = getRuntimeContext().getBroadcastVariable(confName);

}})

 

Job Manager Schedule confFunction broadcast to Task Context
