hi! I'm trying to pass Configuration parameters to a RichMapFunction in flink streaming and I can't find the way to do it
I need to pass two strings to the MapFunction and I was getting a serialization error, so I tried RichMapFunction and open() but I can't find a way to set the the parameters I get at open(Configuration params) withParameters seems to be only defined for batch from what I've seen. how do I make a serializable MapFunction that receives two strings as configuration from outside its definition?
