These changes have specifically been made for Kafka connector. This will expose a new metric named `fission_mqt_message_lag`, which will show a number of messages lag per topic and partition. We can use this metric in the auto-scaling of the pod for the new deploy type executor function. While creating a new deploy function we need to add hpa metrics of external type inside the function definition.
