Hi team,
I am trying to figure out a way to flatten events in my Flink app.
Event that i am consuming from Kafka is
UpperLevelData {
int upperId;
List<ModuleData> listOfModules
}
ModuleData {
int moduleId;
string info;
}
After consuming this event, i want to flatten it out in following format -
FlinkReshapedData{
int upperId;
int moduleId;
string info;
}
How would I do it? Shall I use process function for it
