java.lang.Object

org.apache.beam.sdk.transforms.DoFn<org.opennms.netmgt.flows.persistence.model.FlowDocument,org.apache.beam.sdk.values.KV<CompoundKey,Aggregate>>

org.opennms.nephron.Pipeline.KeyFlowBy

All Implemented Interfaces:

Serializable, org.apache.beam.sdk.transforms.display.HasDisplayData

Enclosing class:

Pipeline

public static class Pipeline.KeyFlowBy
extends org.apache.beam.sdk.transforms.DoFn<org.opennms.netmgt.flows.persistence.model.FlowDocument,org.apache.beam.sdk.values.KV<CompoundKey,Aggregate>>

Maps flow documents into pairs of compound keys and aggregates. The CompoundKey is determined by the CompoundKeyType given in the constructor. Aggregate values are determined for window based on the intersection of flows with their windows.
