The new metrics don't seem to belong to any existing section, so I added a new one. But our current doc doesn't seem organized well (for example, the metrics in the above link are not only for realtime processes, but for all task types as well), maybe we need to tidy up at some point after https://github.com/apache/druid/issues/10352 is done. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
