Data observability provides comprehensive visibility into the health of an organization’s data and systems, letting you promptly identify discrepancies, pinpoint root causes of related issues, and swiftly enforce corrective measures. This level of data awareness is critical for organizations who rely on accurate information for decision-making.

Data observability tools offer a holistic view of your organization’s data environment so your teams can fully understand and manage data assets. Understanding the data observability pillars and hierarchy and the types of tools available can help you implement a data observability framework for your organization. Here’s what you need to know.

What is Data Observability?

Data observability is a key part of data management that provides an in-depth understanding of the health and quality of an organization’s data across various enterprise systems and processes. It involves monitoring, managing, and maintaining data assets to ensure accuracy, validity, and reliability. The process gives a transparent view of data flows, revealing data inconsistencies and making it easier to troubleshoot and resolve data issues in real-time.

Importance of Data Observability

Data observability equips businesses with a deep understanding of how their data systems are working, providing insights into the performance, behavior, and interactions of data systems. It enables an organization to uncover and resolve data issues proactively. Here are some of the key reasons why data observability is critically important:

  • Transparency: Visibility into the data flow, quality, and performance of an organization can instill stakeholders with an understanding of how data is generated, processed, and used. This builds trust and confidence in decision-making processes.
  • Reliability: By ensuring the accuracy and trustworthiness of data, data observability boosts the reliability of information used for decision-making. It helps find and correct data errors or inconsistencies promptly, minimizing the risk of making decisions based on faulty or incomplete data.
  • Efficiency: Facilitating the rapid detection and resolution of data issues reduces downtime associated with data-related issues. By closely monitoring data pipelines and systems, organizations can optimize performance, maintain operational continuity, and boost productivity.
  • Collaboration: Shared understanding of data assets and processes promotes team collaboration and supports communication, knowledge sharing, and interdisciplinary cooperation, aiding teams in working together effectively towards common goals.

Data Observability vs. Data Monitoring

Data observability and data monitoring differ in their scope and goals—data observability takes a broader approach than traditional monitoring and alerting, providing a more thorough view of data systems. Data monitoring involves continuous surveillance and tracking of data flows and processes to maintain operational health and performance.

Data observability does more than mere surveillance; it employs measures to maintain high data quality, trustworthiness, and usability throughout its lifecycle. In addition, data observability includes aspects such as understanding data lineage, managing metadata, guaranteeing data governance, and supporting collaboration among stakeholders.

In short, monitoring informs you about the functionality of the system, while observability enables you to take a closer look into the underlying reasons for any malfunctions.

Data Observability: The Five Pillars

Data observability can be broken down into five pillars: freshness, distribution, volume, schema, and lineage. These five pillars collectively offer a thorough examination of data health and present vital insights into the quality and trustworthiness of your enterprise data.

The Five Pillars of Data Observability

Pillar 1: Freshness

Data freshness, or recency, measures the timeliness and frequency of data updates and pinpoints gaps in data updates, making sure that pipelines are functioning optimally. Freshness is paramount in decision-making, as outdated data can lead to erroneous conclusions and wasted resources.

Pillar 2: Distribution

Distribution is the way data is dispersed across different systems, locations, or platforms. It measures if data is reliable and accurate by matching it to the expected values. If data differs too much from the normal range, it may suggest a problem with the data source or quality.

Data observability tools can spot and notify you about distribution issues and help you correct them before they affect other parts of the pipeline. Data quality is an important part of distribution because it affects how well the data can serve its intended purpose. If the data is distributed across multiple systems or databases, it needs to be consistent, accurate, complete, and valid. Otherwise, the data may not be reliable.

Pillar 3: Volume

Assessing the quantity and completeness of data processed through various processes and pipelines can give insights into its health and reliability. It can be a critical indicator of whether data intake aligns with anticipated thresholds. Similar to distribution, volume ensures that the amount of data received is consistent with historical patterns. Significant deviations in the volume of data may indicate issues.

Pillar 4: Schema

Schemas determine how data is structured and organized in tables, columns, and views. Changes to the schema can cause issues or discrepancies, so monitoring who makes these changes and when is necessary for understanding the health of your data ecosystem.

Data observability verifies that data is organized consistently, is compatible across different systems, and maintains its integrity throughout its lifecycle. Establishing a clear process for who updates the schema and how they do it is a key aspect of a data observability strategy.

Pillar 5: Lineage

This data observability pillar focuses on tracing the impact of changes on data and explains where the data came from in case of issues. Lineage tracks the journey of data from its source to its destination, recording any changes along the way, including what, why, and how the data has been modified.

Lineage is typically presented visually to present a clear understanding of the data flow. It identifies the upstream sources and downstream ingestors affected by changes, as well as the teams generating and accessing the data. Advanced lineage also collects metadata about the data related to governance, business, and technical guidelines associated with specific data tables. This information serves as a single source of truth for everyone, promoting data consistency and reliability.

Understanding the Data Observability Hierarchy

The data observability hierarchy is a structured approach to monitoring and validating data quality and reliability. An integral part of the data observability process, it provides a systematic way to gain visibility into the state of data at different levels of granularity. By following this hierarchy, your organization can ensure the accuracy, reliability, and trustworthiness of your data at every level, ultimately enhancing the overall data observability process.

Level 1: Operational Health and Dataset Monitoring

This level involves essential metadata and gives a high-level overview of data operations, ensuring the timely arrival of data in the correct format. By keeping an eye on operational health and dataset, you can catch and resolve any issues early, which helps maintain the overall quality of your data.

Level 2: Column-Level Profiling

This level involves a detailed examination of specific data categories to solidify existing rules and create new ones. It involves checking if the data is dependable, predictable, and consistent while finding inconsistencies, outliers, or anomalies. This level of insight can refine the accuracy of your data analyses and predictions.

Level 3: Row-Level Validation

This level entails a microscopic examination of each individual piece of data against specific rules or conditions and verifies its correctness to make sure that business rules are being met. This helps you catch any errors or anomalies at the most granular level, making sure data is error-free and reliable.
