“Fundamentals of Data Engineering Part 1" - Fundamentals

Let’s kick off the discussion by reviewing Data Engineering Fundamentals. For anyone new to Data Engineering, this is a must watch episode. We will review the book’s definition of data engineering and discuss a high-level overview of the lifecycle, the data architecture, and the supporting technologies. If you joined our original Data Mesh book club, you have a foundational understanding of Data Mesh. This session will give you a foundational understanding of Data Engineering, before we start to describe the synergies in Part 2. ... Data engineering is a rapidly evolving field that plays a crucial role in managing and transforming data for meaningful insights and decision-making. We discuss the definition of a data engineer, the scope of their responsibilities, and the evolving landscape of data engineering. Defining Data Engineering: Data engineering goes beyond mere technology. It encompasses life cycle management and requires addressing concepts like raw data, high quality, and consistent information. The complexity and breadth of the field are highlighted, leading to a realization that the role of a data engineer may vary depending on the specific domain and organizational context. Challenges in Data Science Hierarchy: A critical challenge highlighted in the conversation is the disproportionate amount of time spent by data consumers on lower layers of the data science hierarchy. The participants cite statistics suggesting that 70% to 80% of their time is consumed by tasks that should ideally be handled by data engineers. This finding underscores the importance of optimizing the data engineering aspects to enable data scientists and analysts to focus on generating insights and taking action based on the data. The Evolving Scope of Data Engineering: There are a broad range of activities and responsibilities associated with data engineering. It emphasizes that data engineers must have a holistic understanding of various elements, including cost optimization, performance optimization, and interoperability. Data engineers are no longer just technical experts but also need to comprehend the business context and the underlying architecture. While acknowledging the significance of all these aspects, it is also important to recognize that optimizing for each element may vary based on organizational priorities, such as agility, robustness, reusability, and simplicity. Conclusion: Data engineering is a multifaceted discipline that plays a vital role in managing and transforming data for organizational success. As discussed, the role of a data engineer encompasses tasks ranging from data sourcing to serving insights to data consumers. The evolving landscape of data engineering necessitates a deep understanding of diverse elements, including cost optimization, performance, and interoperability. By addressing these challenges and optimizing data engineering efforts, organizations can unlock the full potential of their data and empower data scientists and analysts to generate valuable insights. #dataengineering #dataengineer #datapipeline #data #dataanalytics #datascience #datagovernance #datamesh
