  • Replace the "reinsertion" design with release with real "release last ref" design.
  • Rename some APIs.
• Refine metrics framework:
  • Replace metrics with customized metrics framework to support various metrics backend.
  • Implement built-in metrics exporter that adapts to crate prometheus/prometheus-client/opentelemetry.
