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
