## Overview

This small Airflow project schedules a daily Twitter extraction, refines returned tweets into selected fields, and writes them to a CSV file. The DAG invokes the ETL function; that function performs the API request and handles refinement and export. The README provides little architectural detail, and although `s3fs` is imported, the sampled ETL code does not use it, so no S3 integration is shown.

Main entry points: [`twitter_dag.py`](https://github.com/darshilparmar/twitter-airflow-data-engineering-project/blob/main/twitter_dag.py) (Daily DAG), [`twitter_etl.py`](https://github.com/darshilparmar/twitter-airflow-data-engineering-project/blob/main/twitter_etl.py) (ETL function)

## Components

### Orchestration

- [Daily DAG](https://github.com/darshilparmar/twitter-airflow-data-engineering-project/blob/main/twitter_dag.py): `twitter_dag.py`

### Tweet ETL

- [ETL function](https://github.com/darshilparmar/twitter-airflow-data-engineering-project/blob/main/twitter_etl.py): `twitter_etl.py`
- [Tweet refinement](https://github.com/darshilparmar/twitter-airflow-data-engineering-project/blob/main/twitter_etl.py): `twitter_etl.py`
- **Refined CSV**

### Other components

- **Airflow scheduler**
- **Twitter API**

## Connections

- Airflow scheduler → Daily DAG: triggers schedule
- Daily DAG → ETL function: invokes
- ETL function → Twitter API: requests timeline
- Twitter API → Tweet refinement: returns tweets
- Tweet refinement → Refined CSV: writes CSV
