[GitHub] [pinot] jackjlli opened a new pull request, #9001: Remove double counting on pinot-server

jackjlli opened a new pull request, #9001:
URL: https://github.com/apache/pinot/pull/9001

   This PR removed the double counting on pinot-server if `PriorityScheduler` is used.
   
   The value of `QUERIES` metric has already been in https://github.com/apache/pinot/blob/master/pinot-core/src/main/java/org/apache/pinot/core/transport/InstanceRequestHandler.java#L111, there is no need to update the metric value again.
   
   I also validated that there is no other server metrics having this duplication issue.

   > Aren't both of these metrics under different groups? The one removed in this PR is for `tableNameWithType` but the one not removed [in the mentioned link](https://github.com/apache/pinot/blob/master/pinot-core/src/main/java/org/apache/pinot/core/transport/InstanceRequestHandler.java#L111) is under global group i.e. combined metric for all the tables.
   
   Good question! If you take a look at the metric definition, the 2nd parameter is `true`, which means that the metric is a global metric. 
   https://github.com/apache/pinot/blob/09fcdd59cc07e2faa154858075473cdec3518b60/pinot-common/src/main/java/org/apache/pinot/common/metrics/ServerMeter.java#L28
   
   Plus, the metric is only emitted in `PriorityScheduler` but not in other ones. If we really want a table level metrics, it'd be good to add a new one and add it to all the schedulers.
