io.delta.kernel.internal.metrics.ScanMetrics

public class ScanMetrics
extends Object

Stores the metrics for an ongoing scan. These metrics are updated and recorded throughout the scan using this class.

At report time, we create an immutable ScanMetricsResult from an instance of ScanMetrics to capture the metrics collected during the scan. The ScanMetricsResult interface exposes getters for any metrics collected in this class.
