All Implemented Interfaces:

VeniceDimensionInterface, Serializable, Comparable<VeniceDCROperation>, Constable

public enum VeniceDCROperation
extends Enum<VeniceDCROperation>
implements VeniceDimensionInterface

Dimension values for the VeniceMetricsDimensions.VENICE_DCR_OPERATION dimension, representing the type of deterministic conflict resolution (DCR) merge operation performed during active-active replication.

When a record update arrives at an active-active enabled store, the ingestion pipeline must merge the incoming update with the existing record using DCR logic. This dimension captures which type of merge operation was executed, enabling latency and throughput analysis per operation type.

Used by the ingestion.dcr.merge.time metric to break down DCR merge latency by operation type.
