public interface GenericQueryMetricsFactory
QueryMetrics
implementations for all query types, which don't (yet)
need to emit custom dimensions and/or metrics, i. e. they are good with the generic QueryMetrics
interface.
Implementations could be injected using
PolyBind
.optionBinder(binder, Key.get(GenericQueryMetricsFactory.class))
.addBinding("myCustomGenericQueryMetricsFactory")
.to(MyCustomGenericQueryMetricsFactory.class);
And then setting property:
druid.query.generic.queryMetricsFactory=myCustomGenericQueryMetricsFactory
Unlike QueryMetrics
itself, this interface is considered stable and is expected to be injected into custom
Query extensions that do not want to worry about the potential instability of QueryMetrics
