In the fast-paced world of modern technology, data is the lifeblood of organizations. It fuels decision-making, drives innovation, and underpins virtually every aspect of business operations. However, the ever-increasing complexity of IT infrastructures and the proliferation of data sources have made it challenging for companies to comprehensively understand their data health. This is where Data Observability comes into play, offering the ability to understand, diagnose, and manage data health across operational data pipelines.

Unveiling Data Observability

At its core, data observability represents a comprehensive understanding of the health and performance of data within an organisation’s systems, data pipelines and analytics platforms.

It’s more than just passive surveillance; it offers profound insights into the state of data and the reasons behind any anomalies or issues. This encompasses not only alerting mechanisms but also real-time analytics that delve deep into the realms of applications and network infrastructure.

The Essence of Data Observability

The essence of data observability can be dissected into three primary components:

1. Discovery, Profiling, and Monitoring: This phase involves collecting comprehensive information about the data’s location, content, and usage patterns, followed by proactive and continuous monitoring.
2. Analysis: Leveraging cutting-edge technologies like Artificial Intelligence (AI) and Machine Learning (ML) for intelligent analysis, organizations can assess historical data trends and swiftly identify outliers.
3. Visualization and Alerting: Providing key stakeholders with dashboards for real-time data activity visualization and issuing proactive alerts for potential issues. Additionally, contextual information is provided to facilitate informed decision-making.

5 Dimensions of Data Observability

To comprehend the intricacies of data observability, it’s essential to understand the five key dimensions it manages:

1. Freshness: Freshness assesses the timeliness of your data tables and the frequency of updates. Data that hasn’t been refreshed as frequently as is required for its use case, due to pipeline failures or other poor data management practices, can slow operations and lead to bad business decisions.
2. Volume Monitoring: Unexpected surges in the number of new data records can be indicative of issues. For instance, Amazon once faced a scenario where a news anchor’s on-air request, “Alexa, order me a dollhouse,” prompted numerous unintentional orders due to viewers’ devices responding. By actively monitoring for unusually high order volumes, companies can promptly identify and address such issues.
3. Schema Changes: Data observability extends to tracking alterations in data schemas within databases. When a new column is introduced to a customer database, it can have significant implications for data analytics. Records predating the change may contain null values or default values for the new field, impacting data analysis. Leveraging data catalogue solutions that document schema changes becomes pivotal in data observability.
4. Distribution Tests: These tests evaluate whether data values fall within a normal or acceptable range. For instance, in a medical study, patients with extreme weights, like less than 25 or more than 200 kilograms, would raise red flags as potential data entry errors.
5. Lineage: When data issues arise, knowing “where” is essential. Data lineage reveals which upstream sources and downstream consumers are affected. It also collects metadata related to data governance, business rules, and technical guidelines. Time slicing allows data engineers to quickly troubleshoot where breaks occur.

Data Observability vs. Data Monitoring

At first glance, data observability might appear as a sophisticated monitoring system designed to flag anomalies. However, it goes beyond mere monitoring, offering insights that enable data stewards to comprehensively assess the overall health of their enterprise data.

Consider a medical analogy:

When a hospital’s nursing team periodically records a patient’s vital signs, they are essentially monitoring basic metabolic facts. In contrast, data observability equips the medical team with continuous data collected via diagnostic tools, providing in-depth insights into the patient’s health and potential issues.

The finest data observability tools leverage advanced technologies, including machine learning, to detect patterns in enterprise data and alert data stewards when anomalies emerge. This proactive approach empowers business users to tackle problems and potential issues as they surface, resulting in healthier data pipelines, enhanced team productivity, and greater customer satisfaction.

Data Observability vs. Data Profiling

Data observability and data profiling are both important concepts in data management, but they have different goals and approaches.

• Data observability is the practice of monitoring data in motion to identify and troubleshoot problems. It involves collecting data about the data itself, such as its structure, content, and relationships. This data is then used to create a comprehensive view of the data’s health and performance.
• Data profiling is the practice of inspecting data at rest to identify its quality and characteristics. It involves collecting data about the data’s attributes, such as its type, format, and distribution. This data is then used to create a profile of the data that can be used to improve its quality and understand its behaviour.

In short, data observability is concerned with the health and performance of data in motion, while data profiling is concerned with the quality and characteristics of data at rest.

Feature	Data Observability	Data Profiling
Goal	Identify and troubleshoot problems	Understand the quality and characteristics of data
Focus	Data in motion	Data at rest
Techniques	Monitoring, alerting, root cause analysis	Inspection, analysis, reporting
Benefits	Improved data quality, reliability, and performance	Improved data understanding and decision-making

Data observability and data profiling are complementary practices.

Data observability can help to identify problems with data quality, while data profiling can help to understand the root cause of those problems. By combining these two practices, organizations can improve the quality and reliability of their data.

Here are some examples of how data observability and data profiling can be used together:

• A data engineer uses data observability to identify a problem with the data pipeline. They then use data profiling to understand the root cause of the problem, such as a missing field or an incorrect format.
• A business analyst uses data observability to identify a trend in the data. They then use data profiling to understand the factors that are driving the movement, such as changes in customer behaviour or product performance.

By combining data observability and data profiling, organizations can gain a deeper understanding of their data and use it to make better decisions.

The Significance of Data Observability

In today’s data-centric business landscape, trust in data is non-negotiable. Data is pivotal for identifying strategic opportunities, supporting tactical decisions, and powering AI/ML models that automate routine tasks. Data observability plays a pivotal role in ensuring data’s trustworthiness and reliability, delivering several key benefits:

1. Ensure Trustworthy Data for Accurate Reporting and Analytics: By identifying anomalies and proactively alerting relevant stakeholders, data observability enables organizations to be proactive rather than reactive. This proactive approach addresses data issues before they can disrupt business operations, averting potentially costly downstream problems.
2. Reduce Costs and Time to Resolution for Operational Issues: Data observability furnishes crucial information that facilitates quick identification of the root cause of issues. This translates to resolving problems before they can inflict significant harm.
3. Reduce Risk in Transformation Initiatives: In an era of digital transformation, data observability is indispensable. As businesses undergo rapid changes and manage more data than ever before, it empowers data engineers and other users with a profound understanding of their data’s state and health.
