I have a question regarding Flink SQL, which I'm lately getting into. So far, my experience is with the DataStream API mostly. In that context, it's easy for me to generate metrics for my operators. However, I'm just wondering which level of control there is regarding monitoring & metrics when working with Flink SQL. Is it possible to define "metrics for your queries"? Whatever that means and assuming that it makes any sense :laughing:. At least I should be able to generate typical metrics for common connectors, e.g., messages read/produced & things like accumulated lag for the case of the kafka connector, to put an example. Sorry for the vagueness, but I could not find a section for metrics & monitoring within the Flink SQL docs.
Any guidance would be appreciated! Salva
