• Data Observability Definition

  Data Observability Definition

  Data observability involves monitoring, managing, and maintaining data. It can give you a deep understanding of your data’s health, quality, and reliability across the many systems and pipelines within your organization. Organizations can identify, troubleshoot, and fix data issues quickly and proactively by engaging in service level agreement (SLA) tracking, root cause analysis, logging, data lineage tracking, and automated management.

  Data observability has five pillars: freshness, quality and distribution, volume, schema, and lineage.

  • Freshness: Refers to how up-to-date the data tables are and how regularly the data is updated. If data is left un-updated for an extended period, it will become stale and cause people to make poorly informed decisions. This can lead to wasted time, energy, and money.
  • Quality and distribution: Revolves around the data’s quality and how it’s being accessed. Quality and distribution involve looking at collected data to see if the deviations fall within an acceptable range and analyzing metrics, such as accuracy, consistency, and completeness. By monitoring data quality and distribution, you can ensure your data is reliable and trustworthy.
  • Volume: Concerns the amount of data generated and moved through an organization’s processes and pipelines. Volume can also refer to the completeness of data tables, shedding valuable light on the health of your data sources and the overall performance of data pipelines.
  • Schema: Refers to how the data is organized. Schema changes can lead to broken data—and if the changes aren’t properly monitored, they’re easy to miss. Data observability and monitoring allow organizations to see how their data is organized and how it has evolved. Not only does this help prevent issues such as data mismatches, loss, or corruption, but it also leaves organizations with accurate, consistent, and reliable data, which allows for better analysis and decision-making.
  • Lineage: Helps organizations understand where data has broken. By examining data from its source, looking at the data’s end destination, and discovering what changed, why it changed, and how it changed, lineage provides a clear, comprehensive view of the data’s journey, making it easier for organizations to identify and resolve issues and maintain high data integrity.

• Data Observability vs. Data Monitoring

  Data Observability vs. Data Monitoring

  Data monitoring means continually monitoring data flow and system performance to ensure things are operating as they should. Data monitoring solutions can help organizations uncover processing delays, data loss, bottlenecks, and other issues with the potential to impact a data system’s performance and reliability. These tools typically rely on threshold-based alerts, notifying users when specific metrics deviate from predefined limits and enabling quick corrective actions. As a result, organizations can more easily stay on the right side of compliance standards and SLAs.

  While effective for immediate problem detection, data monitoring provides a relatively narrow, surface-level view of a system’s health. Essentially, it’s only the tip of the iceberg—and data observability takes data monitoring a step further.

  Instead of simply monitoring data flow and system performance for issues such as data loss and bottlenecks and relying on threshold-based alerts, data observability takes a deeper, more holistic approach.

  With the help of a data observability platform, users have visibility across the entire lifecycle of data and can better understand the system’s internal state along with every portion of the data pipeline. Not only can a data observability platform analyze current metadata, but it can also dive into historical metadata for deeper, more accurate insights.

  Data observability tools can collect and analyze metrics, logs, traces, queries, and more in real time, allowing organizations to understand root causes, detect anomalies, and proactively address potential problems before they escalate. Data observability platforms help eliminate silos by integrating data from various sources, fostering a unified view of the system. They also aid in identifying potential data quality degradation, allowing teams to intervene and prevent problems that could compromise data integrity.
• Data Observability vs. Data Quality

  Data Observability vs. Data Quality

  Data observability and data quality are two distinct but related terms. While data observability is concerned with monitoring and tracking data systems in real time to quickly identify downtime, anomalies, performance bottlenecks, and other issues, data quality monitoring involves measuring the data’s condition.

  Data quality is usually measured by the data’s accuracy, consistency, completeness, validity, timeliness, and uniqueness. A data observability tool helps to improve each of these aspects, which allows organizations to achieve higher data quality. It can tell organizations whether the data is reliable enough to serve as the foundation for analytics and operational decision-making.

  Data observability can have a direct impact on data quality, as a higher level of data observability allows organizations to discover unexpected data patterns, schema changes, pipeline failures, and more, leading to higher data quality. However, data observability tools can’t single-handedly resolve all data quality issues. Organizations need to engage in careful quality monitoring to improve data quality and prevent data problems from occurring in the first place.
• Why Is Data Observability Important?

  Why Is Data Observability Important?

  Having poor data quality is all too common. For extended periods, many organizations don’t realize their data is bad, leading to flawed decision-making, lost opportunities, operational inefficiencies, and worse. Unreliable data can impact everything—from compliance efforts to customer experiences to an organization’s overall reputation.

  Data observability is vital because it allows organizations to proactively monitor the health and integrity of their data systems. Data observability solutions place deep insights and valuable metrics from across your entire data ecosystem at your fingertips. Not only does this allow you to ensure your data is complete, accurate, and reliable, but it also enables you to identify and address problems, such as anomalies and bottlenecks, before they escalate and significantly impact operations.

  As a result, organizations can better meet their data SLAs, reduce data downtime, and more effectively allocate their resources. Additionally, those in charge of making decisions will have higher-quality data, which can lead to better, more informed choices.

  With the growing reliance on AI, ML, and other data-driven technologies, having reliable, accurate data is more important than ever. Poor data quality could result in data, schema, and model drift, leading to decreased AI and ML model performance, inaccurate predictions, and misguided decision-making when it comes to budgeting, product development, the customer experience, and more.
