> The Spark metrics system produces many different metrics and not all of them
> are used at the same time. This proposes to introduce a configuration
> parameter to allow disabling the registration of metrics in the "static
> sources" category, in other to reduce the load and clutter on the sink, in
> the cases when the metrics in question are not needed. The metrics registerd
> as "static sources" are under the namespaces CodeGenerator and
> HiveExternalCatalog and can produce a significant amount of data, as they are
> registered for the driver and executors.
