# Lakeflow Jobs Development

**FIRST**: Use the parent `databricks-core` skill for CLI basics, authentication, profile selection, and data exploration commands.

Lakeflow Jobs orchestrate data workflows with multi-task DAGs, flexible triggers, and comprehensive monitoring. Jobs support diverse task types and can be managed via Asset 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](references/task-types.md) |
| Set up triggers and schedules (cron, periodic, file arrival, table update, continuous) | [references/triggers-schedules.md](references/triggers-schedules.md) |
| Configure notifications, health rules, retries, timeouts, queues | [references/notifications-monitoring.md](references/notifications-monitoring.md) |
| Complete worked examples (ETL, warehouse refresh, event-driven, ML training, multi-env, streaming, cross-job) | [references/examples.md](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:

```bash
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

After scaffolding, create `AGENTS.md` in the project directory to provide agents with project guidance. Use this content:

```
# Declarative Automation Bundles Project

This project uses Declarative Automation Bundles (formerly Databricks Asset Bundles) for deployment.

## Prerequisites

Install the Databricks CLI (>= v0.288.0) if not already installed:
- macOS/Linux with Homebrew: `brew tap databricks/tap && brew install databricks`
- Linux without Homebrew: download the versioned archive from the [official releases](https://github.com/databricks/cli/releases), verify the published checksum, inspect its contents, and install the binary only after explicit approval
- Windows: `winget install Databricks.DatabricksCLI`

Never pipe a remote installer directly into a shell. Verify the installed binary with `databricks -v`.

## For AI Agents

Read the `databricks-core` skill for CLI basics, authentication, and deployment workflow.
Read the `databricks-jobs` skill for job-specific guidance.

If skills are not available, install them: `databricks aitools install`
```

## Quick Start

### Asset Bundles (DABs) — recommended

```yaml
# resources/jobs.yml
resources:
  jobs:
    my_etl_job:
      name: "[${bundle.target}] My ETL Job"
      tasks:
        - task_key: extract
          notebook_task:
            notebook_path: ../src/notebooks/extract.py
```

### Python SDK

```python
from databricks.sdk import WorkspaceClient
from databricks.sdk.service.jobs import Task, NotebookTask, Source

w = WorkspaceClient()

job = w.jobs.create(
    name="my-etl-job",
    tasks=[
        Task(
            task_key="extract",
            notebook_task=NotebookTask(
                notebook_path="/Workspace/Shared/etl/extract",
                source=Source.WORKSPACE,
            ),
        ),
    ],
)
print(f"Created job: {job.job_id}")
```

### CLI

```bash
databricks jobs create --json '{
  "name": "my-etl-job",
  "tasks": [{
    "task_key": "extract",
    "notebook_task": {
      "notebook_path": "/Workspace/Shared/etl/extract",
      "source": "WORKSPACE"
    }
  }]
}'
```
