When you select a specific BigQuery Engine for Apache Flink job, the monitoring interface provides a graphical representation of your pipeline: the job graph. The graph page in the console also provides job details, job logs, and information about each step in the pipeline.
The job graph represents each operator in the pipeline as a node. An operator is a single transform, source, or sink. Each node contains the operator name and information about the job status, which includes the following:
- Running: the step is running
- Succeeded: the step finished successfully
- Stopped: the step stopped because the job stopped
- Unknown: the step failed to report status
- Failed: the step failed to complete
The arrows between the nodes indicate the flow of data through the pipeline. To see operator-specific metadata, click the node in the graph.
