Hi Ardhani, So whenever I want to run this flink job, I will call the Java API to put the data to the four different kafka topics, what data to put into kafka will be coded into those API and then once that is complete, I want to run the flink job on the available data in the kafka and perform business operation on all the available data.
I am not sure whether kafka as a datasource will be best for this use case, but somehow I don't want to expose my flink job to database tables directly.
