What is the data mesh?

Permalink to “What is the data mesh?” #

Data mesh is a cultural and organizational shift for data management focusing on federation technology that emphasizes the authority of localized data management. Data mesh is intended to enable easily accessible data by the business. Data assets are analyzed for usage patterns by subject matter experts, who determine data affinity, and then the data assets are organized as data domains. Domains are contextualized with business context descriptors. Subject matter experts use the patterns and domains to define and create data products. Data products are registered and made available for reuse relative to business needs.

Data mesh is a paradigm shift in how organizations approach data architecture. The purpose of the data mesh is to enable easily accessible data for the business teams.

Instead of traditional centralized architectures, the data mesh model promotes a distributed system where individual teams manage and build their own data as discrete products. These data products are then federated across different teams with mutually agreed-upon standards.

“Data mesh, at the core, is founded in decentralization and distribution of responsibility to people who are closest to the data in order to support continuous change and scalability.” — Zhamak Dehghani, the creator of the data mesh concept

How does it work?

Permalink to “How does it work?” #

Gartner expands upon the above definition to explain how the data mesh works:

1. Subject matter experts analyze data assets for usage patterns, and then organize them as data domains.
2. These domains are contextualized with business context.
3. Subject matter experts use the patterns and domains to define and create data products.
4. Data products are registered and made available for reuse relative to business needs.

Such an approach helps teams gain autonomy over their domain data while maintaining consistency through federated governance. This enables faster iteration and reduces bottlenecks that plague traditional data platforms.

What is Gartner’s stance on the data mesh?

Permalink to “What is Gartner’s stance on the data mesh?” #

Gartner’s perspective on the data mesh paradigm from their 2022 Hype Cycle for Data Management has stoked vigorous discussion in the industry. The Hype Cycle is a visual representation that outlines the potential risks and rewards of adopting specific technologies or applications.

Gartner places data mesh in the “innovation trigger” phase in 2022, often seen as the conception of a technology’s lifecycle. Interestingly, Gartner also predicts that the data mesh concept will become “obsolete before plateau.”

This forecast does not necessarily imply that the paradigm is currently obsolete. Rather, Gartner thinks it may be supplanted by a different approach before reaching full maturity.

In terms of market penetration and benefits realization, Gartner rates both as “low”. The company projects that as businesses mature in their data governance capabilities, a more centralized approach might once again gain favor.

This shift might seem counter-intuitive, given the current trend towards decentralization. However, it underlines the complex, evolving dynamics of data management.

What are the challenges of the data mesh architecture?

Permalink to “What are the challenges of the data mesh architecture?” #

The allure of data mesh comes with considerable challenges that might have influenced Gartner’s predictions. Among these hurdles, the demand for consistency in data governance stands as a significant consideration.

Before an organization can contemplate adopting a data mesh, it must already have a decentralized approach to governance in place. This necessitates a high level of maturity within the organization, both in terms of culture and processes.

However, many organizations aren’t there yet. Gartner’s 2021 Data and Analytics Governance Survey indicates that only 18% of organizations have reached the maturity level necessary to adopt the data mesh approach successfully.

Other key challenges with the data mesh architecture include:

1. Domain boundary identification

Permalink to “1. Domain boundary identification” #

It can be challenging to define clear boundaries for data domains, especially in complex organizations with overlapping business functions. Teams must agree on ownership while maintaining interoperability.

2. Technical complexity

Permalink to “2. Technical complexity” #

Implementing a data mesh requires significant changes to the existing data infrastructure and could necessitate complex technologies and techniques. This can be difficult for some organizations to manage without proper tooling.

3. Team skills and training

Permalink to “3. Team skills and training” #

A successful data mesh implementation requires each team to possess data management skills. Training teams and ensuring they have the required skillset can be a significant task that delays adoption.

4. Interoperability standards

Permalink to “4. Interoperability standards” #

Ensuring seamless interoperability between different data domains can be challenging. This requires robust standards and protocols that all teams must follow consistently.

5. Cultural change management

Permalink to “5. Cultural change management” #

A data mesh approach requires a significant cultural shift from centralized to decentralized. This may be met with resistance within the organization, particularly from teams accustomed to traditional models.

6. Data quality management

Permalink to “6. Data quality management” #

Ensuring data quality across different data domains managed by different teams presents ongoing challenges. Federated quality requires both local ownership and global standards.

7. Regulatory compliance

Is data mesh DOA?

Permalink to “Is data mesh DOA?” #

Gartner’s prediction about data mesh becoming “obsolete before plateau” prompts the question: What will replace data mesh if it truly becomes obsolete?

Ex-Gartner analyst and current Head of Data Strategy at Profisee Malcolm Hawker believes that Gartner is positioning “data fabric” as the alternative to data mesh.

Data fabric is another emerging paradigm in data architecture that aims to seamlessly integrate data from various sources to support a range of business use cases. However, this view is not universally shared.

Scott Hirleman disagrees with Gartner’s stance, calling it a “vendor-first, technology-first” approach. He suggests that such a perspective may overlook the practical and business realities driving the adoption of decentralized data management practices like data mesh.

Additional data mesh alternatives organizations evaluate include:

• Flexible data lakes: Centralized repositories with improved governance and accessibility features.
• Traditional data warehouses: Enhanced with modern cloud capabilities and self-service interfaces.
• Convergent data hubs: Hybrid approaches that blend centralized and decentralized elements.
• Abstractive data virtualization layers: Solutions that provide unified access without moving data.
• Federated database systems: Distributed databases with coordinated governance frameworks.

What the creator of data mesh thinks

Permalink to “What the creator of data mesh thinks” #

Zhamak Dehghani originally created the concept of a data mesh while working for Thoughtworks. She now leads her own company, Nextdata, which is creating its own set of “data mesh-native” tools to enable the next generation of data sharing.

Dehghani isn’t keen on what she sees as Gartner’s premature declaration of data mesh’s demise. In a comment on Scott Hirleman’s LinkedIn thread, Dehghani says, “If Gartner’s opinion is the result of quantified analysis, I would love to see the raw data behind it.”

Dehghani goes on to note that she works with companies on a daily basis that are implementing data mesh architectures. “…the gap between a single analyst’s point of view and the realities on the ground seems quite vast.”

This highlights an important tension in the industry. While analyst firms provide valuable perspectives, they may not capture the full scope of implementation experiences happening across diverse organizations.

Ready to move forward with data mesh?

Permalink to “Ready to move forward with data mesh?” #

The future of data mesh architecture depends on understanding that different approaches may suit different organizations. Both data mesh and data fabric present viable paths, each with unique strengths and considerations.

The choice between these paradigms should align with the organization’s key challenges and objectives. For companies where data accessibility is the primary concern, the data mesh model could be fitting. For organizations that prioritize data quality and trust, the data fabric approach might be more suitable.

Regardless of the approach chosen, one element remains critical: the data catalog. In either a data mesh or data fabric model, a data catalog is vital for data discoverability and data governance. Modern catalogs enable both centralized oversight and decentralized execution.

Atlan bridges these centralized and decentralized data architecture approaches.
