org.apache.polaris.service.metrics.MetricType

All Implemented Interfaces:

Serializable, Comparable<MetricType>, Constable

@Beta
public enum MetricType
extends Enum<MetricType>

Discriminator for the kind of Iceberg metrics report carried by a MetricsReportEnvelope.

Making the type explicit at the SPI boundary means IcebergMetricsReporter implementations do not need to instanceof-check the raw Iceberg report.
