When implementing data observability, it’s essential to use a combination of manual checks, automated monitoring tools, and possibly machine learning models to ensure comprehensive coverage. Integrating these components provides a holistic view of the data ecosystem’s health and ensures that the data’s quality and reliability support the business’s needs.

What is a data mesh & why is it important? #

Data mesh is a decentralized data architecture and organizational approach. It moves away from the traditional centralized data monolith model and instead treats data as a product. In this approach, domain-oriented teams take responsibility for their data, treating it as a product that they offer to other teams within the organization.

4 Fundamental purposes of a data mesh #

1. Decentralization #

Traditional data platforms often struggle to scale, both in terms of technology and organization. Data mesh seeks to address these challenges by decentralizing data ownership and infrastructure.

2. Speed and agility #

By shifting ownership to domain-oriented teams, there’s faster decision-making, and the teams can be more agile in adapting to their specific needs.

3. Improved data quality #

When teams treat data as a product, they inherently put more focus on its quality, reliability, and usability.

4. Enhanced innovation #

With data easily accessible and in a product-oriented manner, teams across the organization can use it innovatively without relying on a central team for all their data needs.

What are the building blocks of a data mesh? #

The following six key components are the vital building blocks of a data mesh.

Here they are:

Data as a product
Domain-oriented data ownership
Self-serve data infrastructure
Interoperable data products
Data product discovery and documentation
Decentralized governance

Let’s understand each one briefly.

1. Data as a product #

This is the core principle of data mesh. Each data product has its lifecycle, from creation to maintenance, and is owned by a specific team.

2. Domain-oriented data ownership #

Rather than a centralized data team owning all data, domain-specific teams (like marketing, sales, or operations) own and manage their data products. They ensure its quality, reliability, and availability to other teams.

3. Self-serve data infrastructure #

Data infrastructure becomes a platform, providing tools and services for domain teams to manage and share their data products. This decentralizes data tooling and allows for customization to specific domain needs.

4. Interoperable data products #

Though data products are decentralized, they need to be interoperable. This means adhering to organizational standards for data formats, quality, and security, ensuring that teams can seamlessly use data products from other domains.

5. Data product discovery and documentation #

With numerous data products across the organization, discoverability becomes crucial. Comprehensive documentation, catalogs, and search tools ensure that teams can easily find and understand the data products available to them.

6. Decentralized governance #

While central data governance models can become bottlenecks, decentralized governance empowers domain teams to make decisions about their data while still adhering to organizational standards and regulations.

Data mesh represents a paradigm shift in how organizations think about and handle their data. It’s a response to the challenges faced by large-scale, centralized data platforms, aiming to make data more accessible, high-quality, and user-focused by decentralizing its management and infrastructure.

Even though data observability and data mesh are different concepts in the world of data management, are closely related at their heart. At the heart of both ideas is a commitment to the quality, reliability, and usability of data.

While data mesh decentralizes the ownership and infrastructure of data, treating it as a product, data observability ensures the health, quality, and trustworthiness of this data throughout its lifecycle.

The symbiotic relationship between these two concepts ensures that as organizations distribute their data responsibilities across domains, they maintain rigorous oversight and understanding of their data’s health.

What is observability in data mesh? #

Observability in data mesh refers to the ability to gain detailed insights into the health, quality, and lineage of datasets throughout their lifecycle in a decentralized data architecture.

As organizations transition to treating data as a product within domain-specific teams, data observability ensures consistent monitoring and maintenance of data quality and reliability across these domains.

Diving deeper into the relationship between data observability and data mesh #

The following six factors help us understand the relationship between data observability and data mesh.

1. Data quality and ownership #

Data mesh’s principle of treating data as a product naturally emphasizes the quality of data. As domain teams take ownership of their data products, there’s an inherent responsibility to ensure its quality, completeness, and reliability.

Data observability provides the tools and metrics to gauge and maintain this quality.

2. Decentralization and observability challenges #

As organizations shift from centralized data models to the data mesh model, the complexity of observing data can increase due to multiple sources, formats, and infrastructures.

Data observability tools and practices become even more vital in this decentralized landscape to monitor data health consistently across the organization.
