Previously, each raw datapoint was emitted as its own separate row.\n\n**Why**\n\nThis reduces the number of redundant rows sent to monitoring systems and gives a cleaner, aggregated view of metrics that share the same attributes.\n\n- Area: Telemetry\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 1\/5"}
