   @Shawyeok looking forward to this PR. We have observed significant performance impact with `PrometheusMetricsProvider` enabled. 
   
   For high load scenarios with versions 3.7.0 and 3.8.4 read and update latency is drastically increased. Profiling data shows that 30-40% of CPU is spent on Prometheus related computations and GC activity is greatly increased.
