Explanation
In Databricks, when you trigger a job run using the CLI or API, the response includes a run_id field. This run_id is a globally unique identifier for that specific job run instance.
Key points:
- Globally unique: Each job run gets a unique identifier that distinguishes it from all other job runs in the workspace
- Not concatenated with job_id: The run_id is not simply a concatenation of job_id and run count
- Not a simple counter: It's not just a sequential number of how many times the job has been run
- Not the job_id itself: The run_id is different from the job_id
- Not workspace-wide job count: It doesn't represent the total number of jobs run in the workspace
This unique run_id is essential for:
- Tracking the specific run's status and progress
- Retrieving logs and results for that particular execution
- Monitoring and debugging individual job runs
- Referencing the run in subsequent API calls
When you submit a job run request successfully, Databricks generates and returns this unique identifier to allow you to monitor and manage that specific execution.
