Yet, we waste their valuable time on manual, routine tasks (like manual impact analysis or incident investigation), increasing their frustration and the risk of them leaving. Demand for data engineers goes up by 50% every year, and their salaries are skyrocketing. Severe shortage of data engineering talent caused by two major factors: (i) data engineers have become, due to the growing complexity of the data stack, more critical than any other role as they enable the data pipelines and integrated data structures, and (ii) due to the variety of data technologies and strategies, the data engineering role has evolved and now requires a larger skill set, which makes good data engineers harder to find.(Check out this amazing paper from the IBM System Science Institute.) And that is something!

(We find bugs, we don’t prevent them.) According to research, it is 20 times more expensive to fix a bug in production than to fix the same bug in implementation, and it is 100 times more expensive than fixing it in the design phase. We may have modern data quality / data observability tools, but that is still a very reactive approach. And with our dependency on data, one single incident can cause incalculable damage to the business.

Growing number of data incidents due to our limited ability to assess the end-to-end impact of to-be implemented changes.

It also leads to frustration both on the business side (depending on data they don’t trust, waiting a long time to get even basic questions answered) and the technology side (time wasted searching for the same answers about the origin of data again and again).

Decreasing level of trust in reports, dashboards, and insights as we cannot fully explain how the numbers we present were calculated and what their origins and associated data quality or data privacy attributes are.

It distracts developers and slows down the delivery of new features by almost 100%. Statistics from our customers show that up to 40% of data engineering resources are spent on unproductive impact analysis, just assessing the impact of new development requirements.

Slower delivery of new analytical/predictive insights due to limited understanding and control of the environment.

Such an ecosystem is too much for a human brain to handle, too diverse, too interconnected. And all that time, our data infrastructure was growing in complexity-from batch-processed structural data, we evolved to a crazy ecosystem with thousands of components aimed at one goal: to derive more value from data in an ethical way. And then, we started asking questions about privacy, trying to establish boundaries for what is ethical and what is not. From the early days of business intelligence, using historical data to get business insights, we have moved to the big data era, collecting data without thinking about why and training modern AI/ML algorithms to predict the future of our businesses. Why Are We Talking about Data Lineage in 2022?ĭata management has undergone a massive transformation in the past decade. Such a map is the core component of a modern data stack, allowing us to tame its complexity, remain efficient, and avoid regulatory or similar penalties.ĭata Lineage as an Enabler of Metadata Management by Irina Steenbeek, Ph.D.

How to divide a data system into smaller chunks that can be migrated to the cloud independently without breaking other parts of the system.What the best subset of test cases is that will cover the majority of data flow scenarios for your newly released pricing database app.How changing a bonus calculation algorithm in the sales data mart will affect your weekly financial forecast report (and if you are going to like it).Why is that so important? Here are a few examples that go beyond the traditional definition of data lineage.

Data lineage represents a detailed map of all direct and indirect dependencies between data entities in the environment. Traditionally, data lineage has been seen as a way of understanding the data journey through all your data processing systems: what sources the data comes from, where it is flowing to in the environment, and-last but not least-what happens to it along the way.īut real data lineage is far more than that.
