Package org.apache.flink.runtime.scheduler.metrics

Class DeploymentStateTimeMetrics

java.lang.Object

org.apache.flink.runtime.scheduler.metrics.DeploymentStateTimeMetrics

All Implemented Interfaces:

ExecutionStateUpdateListener, MetricsRegistrar, StateTimeMetric

public class DeploymentStateTimeMetrics
extends Object
implements ExecutionStateUpdateListener, StateTimeMetric, MetricsRegistrar

Metrics that capture how long a job was deploying tasks.

These metrics differentiate between batch & streaming use-cases:

Batch: Measures from the start of the first deployment until the first task has been deployed. From that point the job is making progress.

Streaming: Measures from the start of the first deployment until all tasks have been deployed. From that point on checkpoints can be triggered, and thus progress be made.
