  • Give you more information each data stage in progress for Data Pipeline and ETL

2. Airbyte - What is Data Extraction? Data Extraction Tools and Techniques

  • Explain the theory of Data Extraction and list main stage of this progress
  • Give you couple of methods and techniques related Data Extraction
  • Comparison btw Data Extraction and Data Mining
  • Challenge and how we can handle extraction for empowering business
  • Tools and usage for applying ETL for Data Extraction, and learn how to automate that one
  • Relate to best practices in Data Extraction
  • In the end, you will have couple of example real world with applying Data Extraction progress

3. Airbyte - What is Data Pipeline: Benefits, Types, & Examples

  • Explain the theory of Data Pipeline with couple of benefits of them and what components inside data pipelines, such as Origin, Destination, Dataflow, Storage, Workflow and Monitoring
  • List a couple of data pipeline styles with explaining
  • Covey some example for relating what use-case should use data pipelines

4. Medium - dbt in Production: Airflow with Kubernetes

  • Learn about challenge when use DBT inside the scaling system, with many things problems can be occur, such as conflict package, managed airflow, …
  • They want to bring DBT with concept Airflow and Kubernetes, because they will use KubernetesPodOperator for scale up DBT and use this pod created new DBT for each task
  • List about couples of tech debt need to solve when use this strategies for logging and save artifact

5. Medium - Airflow: Why is nothing working?

  • We will learn about problem of Bluecore when setup airflow and use SubDagOperators to cause Deadlock for Data Pipeline with scale up Celery but not solving
  • They try to explain why they configure wrong and what happen inside their system and give the solution for tackling problem. From step to simple disassemble, they know about the SubDagOperator mess up with executing child Dag and parrent Dag should wait before child completely and child dags not finish and cause deadlock.
