In this second installment of the Dataflow course series, we are going to be diving deeper on developing pipelines using the Beam SDK. We start with a review of Apache Beam concepts. Next, we discuss processing streaming data using windows, watermarks and triggers. We then cover options for sources and sinks in your pipelines, schemas to express your structured data, and how to do stateful transformations using State and Timer APIs. We move onto reviewing best practices that help maximize your pipeline performance. Towards the end of the course, we introduce SQL and Dataframes to represent your business logic in Beam and how to iteratively develop pipelines using Beam notebooks.

Syllabus - What you will learn from this course
Este módulo é uma introdução ao curso e ao conteúdo dele.
Resumo dos conceitos do Beam
Confira os principais conceitos do Apache Beam e como aplicá-los na criação dos seus próprios pipelines de processamento de dados.
Janelas, gatilhos de marcas d'água
Neste módulo, você aprenderá a processar dados em streaming com o Dataflow. Para fazer isso, você precisa entender três conceitos principais: como agrupar dados em janelas, a importância das marcas d’água para saber quando a janela está pronta para oferecer resultados e como definir quantas vezes a janela emitirá respostas e a frequência desse processo.
Origens e coletores
Neste módulo, você aprenderá sobre as origens e os coletores no Google Cloud Dataflow. Mostraremos alguns exemplos de DoFn divisível e de E/S de texto, arquivos, BigQuery, Pub/Sub, Kafka, BigTable e Avro. Além disso, mostraremos alguns recursos úteis associados a cada E/S.
Neste módulo, apresentaremos esquemas que são usados por desenvolvedores para expressar dados estruturados nos pipelines do Beam.
Estado e Timers
Neste módulo, falaremos sobre estado e timers, dois recursos avançados que você pode usar na DoFn para implementar transformações com estado.
Neste módulo, falaremos sobre práticas recomendadas e padrões comuns que maximizam o desempenho dos seus pipelines do Dataflow.
Dataflow SQL e DataFrames
Neste módulo, apresentaremos duas novas APIs que representam sua lógica de negócios no Beam: SQL e DataFrames.
Notebooks do Beam
Este módulo é sobre os notebooks do Beam, uma interface para que os desenvolvedores que usam Python comecem a adotar o SDK da plataforma. Isso pode ser feito para criar pipelines de forma iterativa em um ambiente de notebooks do Jupyter.
Este módulo é uma recapitulação do curso.
About the Serverless Data Processing Dataflow em Português Brasileiro Specialization
Está se tornando cada vez mais difícil manter uma pilha de tecnologia que possa acompanhar as crescentes demandas de um negócio orientado a dados. Todo praticante de Big Data está familiarizado com os três V’s do Big Data: volume, velocidade e variedade. E se houvesse uma tecnologia à prova de escala projetada para atender a essas demandas? Entre no Google Cloud Dataflow. O Google Cloud Dataflow simplifica o processamento de dados unificando o processamento em lote e fluxo e fornecendo uma experiência sem servidor que permite que os usuários se concentrem na análise, não na infraestrutura. Essa especialização destina-se a clientes e parceiros que desejam aprofundar sua compreensão do Dataflow para aprimorar seus aplicativos de processamento de dados. Esta especialização contém três cursos: Foundations, que explica como o Apache Beam e o Dataflow trabalham juntos para atender às suas necessidades de processamento de dados sem o risco de dependência do fornecedor Developing Pipelines, que aborda como você converte nossa lógica de negócios em aplicativos de processamento de dados que podem ser executados no Dataflow Operations, que analisa as lições mais importantes para operar um aplicativo de dados no Dataflow, incluindo monitoramento, solução de problemas, teste e confiabilidade.
Frequently Asked Questions
When will I have access to the lectures and assignments?
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
