    What is Data Observability?

    Data observability is the ability to monitor your system’s data, identify data-related issues, and rectify those issues. It’s about observing and understanding the health of your data and ensuring that identified errors do not reoccur. The goal of data observability is to guarantee a reliable flow of high-quality data throughout your organization, thus reducing downtime and improving both short- and long-term decision-making. 

    How Does Data Observability Work?

    Data observability works by continuously tracking data as it moves through complex pipelines. It collects performance metrics from infrastructure, data, and application layers, offering real-time insights into data quality and system health. 

    By monitoring user-defined metrics, data observability identifies anomalies, data inconsistencies, and potential issues, allowing for quick resolution and maintaining data reliability across the entire system. This proactive approach ensures that data remains accurate, consistent, and trustworthy, supporting better decision-making and operational efficiency.

    How Does Data Observability Differ From Data Monitoring?

    To the uninitiated, data observability and data monitoring might seem like two ways of describing the same activity. In reality, data observability and data monitoring are closely related but subtly different.

    Data monitoring examines data in your pipeline with the goal of identifying poor quality data and taking steps to remediate it. Data monitoring tools look especially for data that is incomplete, inaccurate, or doesn’t adhere to defined standards. It essentially asks the question “what’s broken and how can we fix it?”

    Data observability goes beyond basic data monitoring to understanding the data being monitored. It examines not just the quality of the data but also its lineage and schema to provide insight into why it is as it is. It adds the question “why?” to the questions asked in data monitoring. 

    In fact, data observability can enable more accurate and efficient data monitoring and data quality management. By providing a better understanding of why particular data behaves in a certain way, you can better design data monitoring tools to look for specific data quality issues. While data monitoring does a good job looking for pre-defined issues, data observability helps identify new and evolving issues.

    (The following video discusses the differences between data monitoring and data observability.) 

    Understanding Data Observability Metrics

    Data observability metrics are like gauges on a car dashboard, revealing your data system’s health. Key metrics include:

    • Freshness: Ensures you have up-to-date data for analysis.
    • Volume: Unexpected changes can indicate data duplication or missing sources.
    • Distribution: Skewed data distribution can impact analysis accuracy.
    • Schema: Monitors changes to data structure to avoid broken pipelines.
    • Lineage: Tracks data origin and transformation to identify processing errors.

    These metrics help you:

    • Spot potential issues: Proactively identify problems before they impact data quality.
    • Optimize pipelines: Analyze volume and latency to identify bottlenecks for faster processing.
    • Ensure data quality: Track freshness, schema changes, and lineage for consistent data.

    By understanding these core metrics, you gain valuable insights to ensure reliable and high-quality data.

    What Are the Five Pillars of Data Observability?

    Data observability tools evaluate a number of specific issues related to data quality and reliability. Experts often refer to these issues as the five pillars of data observability.

    The five pillars of data observability.

    1. Freshness

    Freshness (sometimes referred to as timeliness) concerns how recent a piece of data is. The goal is to use the most up-to-date data, knowing that data quality erodes over time. For example, customer information becomes less relevant over the years as people move, change email addresses, age, and experience lifestyle changes. Using older data will produce poorer results than working with more timely data.

    2. Distribution

    In this instance, distribution refers to the expected range of a set of data. If data points do not fall within an acceptable range, that may indicate data quality issues. 

    3. Volume

    Tracking the consistency of data flow can help identify data pipeline issues. Erratic data volume can indicate problems with data intake. 

    4. Schema

    Schema refers to how data is organized, such as the fields and tables in a database. Observing changes in schema can indicate broken data, often caused by someone making unauthorized changes to the data structure. 

    5. Lineage

    Data observability pays particular attention to data lineage—that is, the history of a data set. A detailed lineage records every step in the data’s path, include data sources, transformations, and downstream destinations. It provides a complete picture of your firm’s data landscape. 

    Tracking data lineage helps identify where issues occur and why. It’s important for data governance, regulatory, compliance, and ensuring that the data is trustworthy. 

    Other Important Issues

    Beyond the five pillars, data observability is also concerned with understanding:

    • Data quality
    • Data completeness
    • Data security and privacy
    • Data compliance

    The first two of these issues are also in the purview of data monitoring, which reflects how these two activities often serve the same goals. 

    Why is Data Observability Important?

    As the volume of data continues to grow, companies and organizations are expected to ensure the quality and usability of that data. According to IDC, more than 64 zettabytes (ZB) of data were created in 2020. The company expects the amount of data created to grow at a compound annual growth rate (CAGR) of 23% through 2025.

    Volume of data created and replicated worldwide, 2010-2025

    Much of this newly created data is not unique and instead replicated for consumption and analysis throughout an organization. IDC estimates that the ration of unique to replicated data is 1:9, which means that a typical organization will generate nine times as much data as it initially ingests. 

    Ensuring the accuracy, consistency, and reliability of this data is a significant challenge which can only be met by the use of sophisticated data monitoring and data observability tools. This is why 90% of IT decision makers say that data observability is both important and strategic to their business.
