Ensuring data privacy and access control at every stage.
Ingestion is the process of moving data from the source into storage systems.
Monitoring and optimizing cloud compute and storage costs to ensure data operations remain profitable. Key Takeaways for Aspiring and Senior Engineers Focus on "Good Enough" Architecture
Finally, data is made available to the consumers, including data analysts, data scientists, machine learning models, and reverse ETL systems. 3. The "Undercurrents" of Data Engineering
The book had also spawned a series of follow-up books, covering specialized topics such as data architecture, data governance, and machine learning engineering. Joe's work had created a ripple effect, influencing the way companies approached data management and engineering.
: OLTP systems like PostgreSQL or MySQL.
Centralized, structured repositories optimized for fast SQL queries and business intelligence.
: Feeding feature stores for AI model training.
Raw data is rarely ready for end-user analysis. In this stage, data is cleaned, filtered, aggregated, and structured. Modern architectures often favor an pattern over traditional ETL, utilizing the massive compute power of modern cloud data warehouses to transform data after it has been loaded. 5. Serving Data
