## Overview

This small repository contains independent Python examples rather than a documented, connected application. `pipeline/ingest_data.py` downloads January 2021 NYC yellow-taxi data in chunks and writes it to PostgreSQL; `pipeline/pipeline.py` reads a day argument and writes a small example DataFrame to Parquet. `pipeline/main.py` is a standalone greeting entry point. The README provides no further product capabilities or wiring, so no links between these scripts are inferred.

Main entry points: [`pipeline/ingest_data.py`](https://github.com/barnalimohapatra/docker-workshop/blob/main/pipeline/ingest_data.py) (Taxi Ingestion), [`pipeline/pipeline.py`](https://github.com/barnalimohapatra/docker-workshop/blob/main/pipeline/pipeline.py) (Parquet Example)
