Processo de ETL com Python e Airflow usando API do Spotify

Sobre

Projeto de ETL(Extract, Transform e Load) utilizando Python com API do Spotify e Airflow para automatização. Com um token gerado pela própria plataforma do Spotify é possível fazer um request com os dados das músicas que você ouviu, pegando apenas as que eu ouvi nas ultimas 24 horas, montei um processo onde manualmente ou automaticamente com o Airflow esses dados são salvos em um banco de dados SQL. O projeto foi proposto pela youtuber Inglesa Karolina Sowinska e tem como objetivo passar mesmo que de forma básica pelos processos de ETL.

Tecnologias

As seguintes ferramentas foram usadas na construção do projeto:

  • Python
  • Pandas
  • SQLAlchemy
  • Airflow

Extract

Com uma conta gratuita do Spotify, é possível gerar um token que dará acesso as musicas que você ouviu, vale notar que o token expira em algumas horas o ideal seria encontrar uma maneira de atualizar o token automaticamente.

Transform

Depois de extrair os dados, eles são transformados em um arquivo JSON, onde eu posso escolher as informações que eu desejo e coloca-las em um dicionario python. Depois eu transformo esse dicionario em um DataFrame do pandas para facilitar a manipulação.

Load

Utilizando o SQLAlchemy eu crio um banco de dados, esse banco de dados é então alimentado com os dados do DataFrame.

Validação

Há algumas validações básicas, uma que indica se o DataFrame está vazio, outra indica se alguma chave primaria está repetida e uma que checa se existe valores nulos.

Airflow

Construi apenas uma DAG simples para entender como funciona o Airflow, ela rodaria a cada dia de forma automática, executando o código de ETL.
