Key differences between Data Mesh and Data Fabric:

Data Mesh and Data Fabric are two distinct concepts in the field of data management, each addressing different aspects of modern data architecture and data governance. Here, I’ll describe the key differences between Data Mesh and Data Fabric:

1. Core Focus:

  • Data Mesh:
    Data Mesh primarily focuses on the organization’s approach to data ownership, decentralization, and democratization. It addresses the challenges of scaling data management within large organizations by emphasizing domain-specific data ownership and the distribution of data responsibilities to various teams or domains.
  • Data Fabric:
    Data Fabric primarily focuses on data integration, abstraction, and seamless access. It provides a unified and flexible data management framework that allows organizations to integrate, access, and manage data across diverse sources, formats, and locations.

2. Data Ownership and Responsibility:

  • Data Mesh:
    In Data Mesh, domain-specific teams take ownership of their data products, including data quality, data processing, and data consumption. Each team is responsible for their domain’s data.
  • Data Fabric:
    Data Fabric does not prescribe a specific approach to data ownership. It is more concerned with providing a unified and consistent view of data, regardless of who owns it. Data ownership may still be centralized or distributed based on the organization’s needs.

3. Data as a Product:

  • Data Mesh:
    Data in Data Mesh is treated as a product. Cross-functional data product teams are responsible for end-to-end data lifecycle management, including data generation, processing, and consumption.
  • Data Fabric:
    While data management is an important aspect of Data Fabric, it doesn’t inherently focus on treating data as a product. Instead, it provides a framework for data integration and access, leaving the data management approach to the organization.

4. Data Platform vs. Data Architecture:

  • Data Mesh:
    Data Mesh often involves building data platforms that are owned and operated by data product teams. These platforms support the domain-specific data needs of each team.
  • Data Fabric:
    Data Fabric is more of an architectural concept that encompasses data integration, abstraction, and access. It may involve the use of data platforms, but it is not inherently focused on building separate data platforms for each domain.

5. Cultural and Organizational Shift:

  • Data Mesh:
    Implementing Data Mesh often requires a significant cultural shift within the organization. It involves changes in how teams collaborate, communicate, and take ownership of data-related tasks.
  • Data Fabric:
    Data Fabric is more about providing a technical framework for data management and integration. While it may influence data governance practices, it does not necessarily mandate a cultural shift to the same extent as Data Mesh.

6. Data Democratization:

  • Data Mesh:
    Data Mesh places a strong emphasis on democratizing data by allowing more teams and individuals to access and leverage data for their specific needs.
  • Data Fabric:
    Data Fabric also supports data democratization by providing a unified and accessible data layer, but it does not inherently focus on democratization as its primary goal.

In summary, Data Mesh and Data Fabric are distinct approaches to addressing the challenges of modern data management. Data Mesh emphasizes decentralization, domain-specific ownership, and democratization of data, while Data Fabric focuses on data integration, abstraction, and providing a unified data layer. The choice between these concepts depends on an organization’s specific needs, culture, and data management goals.

Data Mesh? Data as product?

Data Mesh is a relatively new concept in the software world that addresses the challenges of managing and scaling data in modern, decentralized, and large-scale data environments. It was introduced by Zhamak Dehghani in a widely-cited 2020 article. Data Mesh proposes a paradigm shift in data architecture and organization by treating data as a product and applying principles from software engineering to data management. Here’s an overview of what Data Mesh means in the software world:

  1. Decentralized Ownership:
    In a Data Mesh architecture, data is not the responsibility of a centralized data team alone. Instead, ownership and responsibility for data are distributed across different business units or „domains.“ Each domain is responsible for its data, including data quality, governance, and usage.
  2. Data as a Product:
    Data is treated as a product, much like software, with clear ownership and accountability. Data product teams are responsible for data pipelines, quality, and ensuring that data serves the needs of the consumers.
  3. Domain-Oriented Data Ownership:
    Each domain within an organization has its own data product teams. These teams understand the specific data needs of their domain and are responsible for the entire data lifecycle, from ingestion and transformation to serving data consumers.
  4. Data Mesh Principles:
    Data Mesh is built on four key principles:
    • Domain-Oriented Ownership: Domains own their data, making them accountable for its quality and usability.
    • Self-serve Data Infrastructure: Data infrastructure is designed to be self-serve, allowing domain teams to manage their data pipelines.
    • Product Thinking: Treat data as a product, with clear value propositions and consumers in mind.
    • Federated Computational Governance: Governance and control are distributed, with a focus on enabling data consumers to make the most of the data while ensuring compliance and security.
  5. Data Democratization:
    Data Mesh promotes data democratization by making data accessible to a broader range of users and teams within an organization. Self-service tools and well-documented data products empower users to access and analyze data without extensive technical knowledge.
  6. Scaling Data:
    Data Mesh is particularly relevant in large-scale and complex data ecosystems. It allows organizations to scale their data capabilities by distributing data ownership and enabling parallel development of data products.
  7. Data Quality and Trust:
    With clear ownership and accountability, Data Mesh encourages a focus on data quality, governance, and documentation. This, in turn, builds trust in the data and promotes its effective use.
  8. Flexibility and Adaptability:
    Data Mesh is adaptable to changing business needs and evolving data sources. It allows organizations to respond more quickly to data demands and opportunities.
  9. Technology Stack:
    Implementing a Data Mesh often involves the use of modern data technologies, data lakes, data warehouses, and microservices architecture. The technology stack should support the principles of Data Mesh and enable decentralized data ownership and management.

Data Mesh represents a shift in how organizations structure and manage their data to meet the challenges of the digital age. By distributing data ownership and treating data as a product, Data Mesh aims to improve data quality, accessibility, and usability while facilitating scalability and adaptability in the face of evolving data needs.

Data fabric?!

Data fabric refers to a comprehensive and flexible data management framework that enables organizations to seamlessly integrate, access, and manage data across diverse data sources, locations, and formats. Data fabric is designed to provide a unified and consistent view of data, regardless of where it resides, whether it’s on-premises, in the cloud, or at the edge. It plays a crucial role in modern data architectures and is particularly relevant in the context of big data, hybrid and multi-cloud environments, and distributed computing. Here are key aspects and components that define the meaning of data fabric:

  1. Data Integration and Interoperability:
    Data fabric solutions are designed to integrate data from various sources, including databases, data warehouses, data lakes, cloud services, IoT devices, and more. They enable seamless data interoperability, ensuring that data can flow freely between different systems and platforms.
  2. Unified Data Access and Management:
    Data fabric provides a unified layer for data access and management, allowing users and applications to interact with data regardless of its location or format. This abstraction layer ensures a consistent and simplified experience for data consumers.
  3. Data Abstraction and Virtualization:
    Data fabric abstracts the underlying data infrastructure, offering a logical representation of data. This means that users and applications interact with a logical view of data without needing to understand the complexities of the physical data storage or technology stack.
  4. Scalability and Flexibility:
    Data fabric solutions are designed to scale with an organization’s growing data needs. They accommodate new data sources, larger datasets, and changing requirements, making them suitable for handling big data and evolving data landscapes.
  5. Data Governance and Security:
    Data fabric incorporates features for data governance, security, and compliance. It provides controls for data access, authentication, authorization, encryption, and auditing, ensuring data is used securely and in compliance with regulations.
  6. Real-Time Data Insights:
    Data fabric enables real-time data processing and analytics by making data readily available for analysis. This facilitates data-driven decision-making and supports business intelligence initiatives.
  7. Cloud and Hybrid Cloud Support:
    Data fabric solutions are typically cloud-agnostic and can seamlessly operate in multi-cloud and hybrid cloud environments. They support data mobility, allowing data to move between on-premises and cloud resources as needed.
  8. Data Resilience and High Availability:
    Data fabric incorporates redundancy, failover, and data replication mechanisms to ensure data availability and minimize downtime in the event of failures.
  9. APIs and Data Services:
    Data fabric often exposes data through APIs and data services, making it easier for developers to access and interact with dataprogrammatically.
  10. Use Cases:
    Data fabric is used in a wide range of use cases, including data integration, data analytics, data warehousing, data migration, data governance, and more.

Data fabric is a crucial component of modern data architecture, enabling organizations to harness the full potential of their data assets, facilitate data-driven decision-making, and adapt to evolving data requirements in an increasingly complex data landscape. It provides the agility and flexibility needed to address the challenges of managing and utilizing data effectively.

What is Kappa Architecture?

Kappa Architecture – Where Every Thing Is A Stream (pathirage.org)

Kappa Architecture is a software architecture pattern. Rather than using a relational DB like SQL or a key-value store like Cassandra, the canonical data store in a Kappa Architecture system is an append-only immutable log. From the log, data is streamed through a computational system and fed into auxiliary stores for serving.

Kappa Architecture is a simplification of Lambda Architecture. A Kappa Architecture system is like a Lambda Architecture system with the batch processing system removed. To replace batch processing, data is simply fed through the streaming system quickly.

But why?

Kappa Architecture revolutionizes database migrations and reorganizations: just delete your serving layer database and populate a new copy from the canonical store! Since there is no batch processing layer, only one set of code needs to be maintained.

Says who?

The idea of Kappa Architecture was first described in an article by Jay Kreps from LinkedIn. Then came the talk “Turning the database inside out with Apache Samza” by Martin Kleppmann at 2014 StrangeLoop which inspired this web site.






An append-only immutable log store is the canonical store in a Kappa Architecture (or Lambda Architecture) system. Some log databases:


In Kappa Architecture, data is fed from the log store into a streaming computation system. Some distributed streaming systems:


The purpose of the serving layer is to provide optimized responses to queries. These databases aren’t used as canonical stores: at any point, you can wipe them and regenerate them from the canonical data store. Almost any database, in-memory or persistent, might be used in the serving layer. This also includes special-purpose databases, e.g. for full text search.

Strange Loop

Strange Loop is a multi-disciplinary conference that brings together the developers and thinkers building tomorrow’s technology in fields such as emerging languages, alternative databases, concurrency, distributed systems, security, and the web.

Strange Loop was created in 2009 by software developer Alex Miller and is now run by a team of St. Louis-based friends and developers under Strange Loop LLC, a for-profit venture.

Some of our guiding principles:
No marketing. Keynotes are never sold to sponsors. The conference mailing lists are never sold or given to sponsors.
Tech, not process. Talks are in general code-heavy, not process-oriented (agile, testing, etc). There are many fine speakers, topics, and conferences in the process area. This is not one of them.
Technology stew. Interesting stuff happens when you get people from different areas in the same room. Strange Loop has a broad range of topics from academia, industry, and a touch of weirdness.
