How does Snowflake support data governance? #

Snowflake, as the primary data storage and processing layer of the data stack, offers features for data asset discovery, collaboration, and governance—collectively known as Snowflake Horizon Catalog.

The Horizon Catalog helps organizations unlock value from their data by enabling discovery and governance within the Snowflake AI Data Cloud.

To make it easier for customers to manage and assign tags and policies, Snowflake Horizon offers an intuitive interface that provides an at-a-glance summary of the total objects, tagged objects and protected objects in an account.” - Snowflake’s definitive guide to data governance summarizes the role of Snowflake Horizon

You can leverage features like:

  • Data quality monitoring with custom data metric metrics and near-real-time alerts
  • Visual data lineage tracking in Snowsight to understand table and column relationships
  • Object tagging and automated sensitive data classification for tracking compliance, discovery, and protection
  • Dynamic masking using SQL statements or Python UDFs
  • Trust Center for monitoring security posture and CIS benchmark compliance
  • Natural language search and AI-generated descriptions for tables and columns to improve discoverability
  • Preserving privacy with aggregation policies, projection policies, differential privacy, and data clean rooms
  • Internal Marketplace for secure data product sharing and collaboration

How are Snowflake users applying its data governance features? #

The above-mentioned Snowflake data governance features have seen increasing adoption as organizations implement unified data governance practices.

According to the Snowflake 2024 Trends Report, Snowflake reported a 70% growth in the application of data governance features across its platform between 2023 and 2024.

This includes advancements in data access controls, tagging, and masking policies, which have enabled organizations to protect sensitive data effectively while still making it accessible for analytical and AI-driven tasks.

We saw that our users were applying more tags governing access and use of their data, meaning that they were ensuring that necessary audiences could make use of their data while restricting unauthorized user access.” - Snowflake 2024 Trends Report

Notably, the number of queries run against protected data increased by nearly 150%, indicating higher utilization of these governed data sets for analysis and machine learning (ML) applications.


What is the role of a metadata-led control plane in enhancing Snowflake data governance? #

A crucial aspect of ensuring better governance as queries against protected objects rise is to ensure smooth interoperability. Most organizations typically use multiple tools and platforms to manage their data. Without proper interoperability, governance policies can become fragmented and inconsistent across different systems.

Snowflake aims to solve this by enabling interoperability between different platforms and tools. One such example is the support for open formats like Apache Iceberg, and another one is the open-sourcing of the Polaris data catalog (now called Snowflake Open Catalog).

This is where a single, metadata-led control plane can make life easier.

One control plane for your entire data stack drives data enablement and self-service by giving you a single interface for interacting with and accessing all your data assets, irrespective of their source.

It democratizes data by enabling everyone in your organization to search and discover any data asset within the ecosystem with various search filters, categories, tags, and other options and then request access to the data asset.

That’s where Atlan’s data and AI control plane complements Snowflake’s Horizon Catalog and Open Catalog.


How does Atlan enhance Snowflake’s native data governance capabilities? #

With Atlan to unify your entire data ecosystem (Snowflake and non-Snowflake assets), you get the following, among other things:

  • An automation-first platform with rule-based playbooks, AI-assisted documentation, DIY connectors, and more
  • An intuitive, multi-layered data asset search and discovery
  • A business glossary and a semantic layer of metrics
  • A governance layer for access control, data privacy, and protection
  • Advanced collaboration and data sharing capabilities
  • Endless extensibility with open APIs

Atlan serves as a metadata-powered control plane, managing search, discovery, business glossaries, lineage, governance, quality, and more.

It’s built on a metadata lakehouse that integrates with all the tools in your data stack. A metadata lakehouse provides a unified repository for all metadata about your data assets, enabling comprehensive governance across your entire data stack.

With such a control plane, you can leverage all the metadata that is already captured by Snowflake in the various schemas, such as ACCOUNT_USAGE, ORGANIZATION_USAGE, MONITORING, etc., in the SNOWFLAKE database.

Atlan also performs two-way sync on object tags, allows you to preview data from Snowflake assets, and mines query history to extract and build a reliable lineage graph, among other things.

With all your metadata in Atlan, you can manage access, discovery, visibility, and governance from a single control plane.

This is exactly how Indica Worldwide leveraged Atlan to become one tool that they used to “understand what’s going on within [its] data estate, what [the] data hold(s), and what its characteristics are, and how it’s being used.”

This was quite challenging for an operation of Indica’s size, as “[it has] some clients who have 40 million customers and build tens upon tens of billions of rows of data. [It’s] Atlan instance right now has something like 500,000 assets in it.”

While Atlan leverages all the native Snowflake data cataloging and governance features, it also offers novel and value-adding features, such as embedded collaboration and active data governance.

These capabilities enable you to collaborate and govern your data better by building upon and activating the inherent value in all the metadata flowing from Snowflake and other tools in your organization’s data stack.


How can you unlock the complete potential of Snowflake with Atlan? #

To get you started and fully onboarded, Atlan provides you with several resources to help you out with Snowflake connectivity. These resources range from step-by-step onboarding for connecting Atlan with Snowflake, crawling metadata from Snowflake, setting up PrivateLink in Azure or AWS, enabling OAuth, and managing Snowflake tags, among other things.

Community examples and use cases #


There’s an active community of Atlan champions that finds innovative ways to incorporate Atlan into their organization’s culture and business processes. These innovations have various themes, including metadata ingestion, documentation culture, project management, and glossary.

Let’s look at some prime examples:

  • Data understanding and standardization: Create a metrics glossary and a business glossary to better understand data assets across the organization and implement a uniform organizational language for metrics and KPIs.
  • Access management and governance: Define personas for data users to better collaborate and govern data across the organization. This goes to the heart of implementing role-based access, data masking, and data sharing controls, among other things.

There are several more of these examples, which you can explore on Atlan’s exclusive community portal.

Best practices and recommendations #


In addition to the community examples, Atlan also has its own recommendations and best practices around metadata ingestion, data security, and privacy. Following these will enable a more secure and functional connection with Snowflake:

  • Use Snowflake’s RSA keypair authentication method as Atlan only supports a secure connection with Snowflake.
  • Choose the ACCOUNT_USAGE method over the INFORMATION_SCHEMA method of fetching metadata from Snowflake.
  • Configure the Snowflake miner to use Atlan’s advanced discovery features like usage and popularity metrics.
  • When you’re using Snowflake’s Business Critical Edition (or above) to meet any security and compliance requirements, you must use PrivateLink (AWS, Azure) to enable a connection between Snowflake and Atlan.

Using all these best practices and recommendations from Snowflake, Atlan, and the community of users who bring these tools together, you can derive the most value from the Snowflake + Atlan integration securely and efficiently.
