Description

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
