Hi, So when you say "you can put the function as a built-in function in the built-in functions directory" you mean that I need to place the jar in this directory, correct?
Also right now I am using version 2.5.0 and I don't really see this config in functions_worker.yml. Is this feature supported in that version and if yes then which dir I can place my jars? Also how do I put that jar in the built-in directory when the cluster is deployed on Kubernetes and say I have a cluster of three brokers running. Do I need to place the jar in each of the brokers built-in directory? If yes how? Is there any api available to do the same?
