  • Control plane: add the AdvanceCrossTierLogStart query rate/time metric to PostgresControlPlaneMetrics.
  • Write path: add CrossTierLogStartReporter metrics (PartitionsReported, ReportErrors, PendingPartitions).
  • Cache: add CrossTierLogStartCache metrics (CacheHits, CacheMisses, CacheSize).
  • Register the new metric groups in MetricsDocs and regenerate metrics.rst.
