Hi team, We noticed that Prometheus metrics exporter exports all of the metrics at the most fine-grained level, which is tremendous for the prometheus server especially when the parallelism is high. The metrics volume crawled from a single host(parallelism 8) is around 40MB for us currently. This is due to *task_name *attribute in the metrics generated by the engine being very long. The task_name attribute is auto-generated from SQL job, and it seems it's attaching all field names onto it.
We want to reduce the metrics volume by either drop task_name or at some more coarse-grained level. But I cannot find any related documents about this, any advice on that?
