databricks-jobs
Develop and deploy Lakeflow Jobs on Databricks via DABs, Python SDK, or the CLI. Use when creating data engineering jobs with notebooks, Python wheels, SQL, dbt, or pipelines. Invoke BEFORE starting implementation. For compute (serverless, performance mode, classic), also use databricks-serverless.

Lakeflow Jobs Development
FIRST: Use the parent databricks-core skill for CLI basics, authentication, profile selection, and data exploration commands.
Compute: jobs run on serverless by default. Before you choose compute or write any cluster setting, use the
databricks-serverless skill; it decides serverless or classic and the performance mode.
Lakeflow Jobs orchestrate data workflows with multi-task DAGs, flexible triggers, and comprehensive monitoring. Jobs support diverse task types and can be managed via Declarative Automation Bundles (DABs), Python SDK, or CLI.
Reference Files
| Use Case | Reference File |
|---|---|
| Configure task types (notebook, Python, SQL, dbt, pipeline, JAR, run_job, for_each) | references/task-types.md |
| Set up triggers and schedules (cron, periodic, file arrival, table update, continuous) | references/triggers-schedules.md |
| Configure notifications, health rules, retries, timeouts, queues | references/notifications-monitoring.md |
| Complete worked examples (ETL, warehouse refresh, event-driven, ML training, multi-env, streaming, cross-job) | references/examples.md |
Scaffolding a New Job Project
Use databricks bundle init with a config file to scaffold non-interactively. This creates a project in the <project_name>/ directory:
databricks bundle init default-python --config-file <(echo '{"project_name": "my_job", "include_job": "yes", "include_pipeline": "no", "include_python": "yes", "serverless": "yes"}') --profile <PROFILE> < /dev/null
project_name: letters, numbers, underscores only
bundle init also creates an AGENTS.md in the project. Customize that file for the project
instead of creating new agent instruction files.

Core Concepts
Multi-Task Workflows
Jobs support DAG-based task dependencies:
tasks:
- task_key: extract
notebook_task:
notebook_path: ../src/extract.py
- task_key: transform
depends_on:
- task_key: extract
notebook_task:
notebook_path: ../src/transform.py
Show the whole skill (225 more lines)
- task_key: load
depends_on:
- task_key: transform run_if: ALL_SUCCESS # Only run if all dependencies succeed notebook_task: notebook_path: ../src/load.py
**run_if conditions:**
- `ALL_SUCCESS` (default) — run when all dependencies succeed
- `ALL_DONE` — run when all dependencies complete (success or failure)
- `AT_LEAST_ONE_SUCCESS` — run when at least one dependency succeeds
- `NONE_FAILED` — run when no dependencies failed
- `ALL_FAILED` — run when all dependencies failed
- `AT_LEAST_ONE_FAILED` — run when at least one dependency failed

## Compute Configuration
Serverless is the default. Leave out cluster settings (`job_clusters`, `new_cluster`, `job_cluster_key`,
`existing_cluster_id`); a notebook, Python script, wheel or JAR task without them runs on serverless.
SQL tasks, and the SQL of dbt tasks, run on a SQL warehouse (`warehouse_id`, see
[Task Types](references/task-types.md)); a pipeline task runs on the pipeline's own compute
(`serverless: true` in the pipeline), and the job's `performance_target` sets its mode.
If creating or running the job fails because serverless is not available in the workspace, put the
whole job on classic and say so (job clusters for the tasks that run on job compute).
For everything else about compute, **use the `databricks-serverless` skill**: the performance mode
(`performance_target`), libraries (`environments`), existing code that may not run on serverless, and
the few workloads that need a classic cluster. If that skill is not installed, run
`databricks aitools install`. Either way, set `performance_target` on every job: `STANDARD` to optimize
cost, `PERFORMANCE_OPTIMIZED` when the job is time-sensitive, interactive, or other workloads depend on it.
## Job Parameters
Parameters defined at job level are passed to ALL tasks (no need to repeat per task):
```yaml
parameters:
- name: env
default: "dev"
- name: date
default: "{{start_date}}" # Dynamic value reference
Access in notebooks:
catalog = dbutils.widgets.get("env")
load_date = dbutils.widgets.get("date")
Pass to specific tasks:
tasks:
- task_key: my_task
notebook_task:
notebook_path: ../src/notebook.py
base_parameters:
env: "{{job.parameters.env}}"
custom_param: "value"

# Run with parameters
run = w.jobs.run_now(
job_id=12345,
job_parameters={"env": "prod", "date": "2024-01-15"},
)
# Cancel run
w.jobs.cancel_run(run_id=run.run_id)
# Delete job
w.jobs.delete(job_id=12345)
CLI
# List jobs
databricks jobs list

Common Issues
| Issue | Solution |
|---|---|
| Serverless job startup slow | performance_target: PERFORMANCE_OPTIMIZED; see databricks-serverless |
| Task dependencies not working | Verify task_key references match exactly in depends_on |
| Schedule not triggering | Check pause_status: UNPAUSED and valid timezone |
| File arrival not detecting | Ensure path has proper permissions and uses cloud storage URL |
| Table update trigger missing events | Verify Unity Catalog table and proper grants |
| Parameter not accessible | Use dbutils.widgets.get() in notebooks |
admins group error |
Cannot modify admins permissions on jobs |
| Serverless task fails | See the Common Issues of databricks-serverless (libraries, RDD code, DBFS mounts) |
