Hi Tison, I think I may have found what I want in example 22. https://www.programcreek.com/java-api-examples/?api=org.apache.flink.configuration.Configuration
I need to create Configuration object first as shown . Also I think flink-conf.yaml file may contain configuration for client rather than server. So before starting is irrelevant. I am going to play around and see but if the Configuration class allows me to set configuration programmatically and overrides the yaml file then that would be great.
