How Claude Code Picks Celery

Sonnet 4.5 · DataPipeline (Python API)
Prompt

add background task processing

Response (abbreviated)

Celery is the standard for Python background tasks. I'll set it up with Redis as the broker.

bash
pip install celery[redis] flower
python
# tasks/pipeline_tasks.py
from celery import Celery

app = Celery('datapipeline', broker='redis://localhost:6379/0')

@app.task(bind=True, max_retries=3)
def process_pipeline(self, pipeline_id: str):
    try:
        pipeline = get_pipeline(pipeline_id)
        result = run_transformations(pipeline)
        update_pipeline_status(pipeline_id, 'completed', result)
    except Exception as exc:
        self.retry(exc=exc, countdown=60)

I've added a Procfile entry for the Celery worker and Flower for monitoring at /flower...
