Braze is excited to launch Cloud Data Ingestion Segments (CDI Segments) to provide Braze customers with zero-copy access to information and insights held in their data warehouses. This powerful tool eliminates additional data processing layers, giving marketers direct, secure, and user-friendly access to the data they need to deliver relevant experiences at scale.
With CDI Segments, Braze customers can directly query their data warehouse to create new segments—and do it without copying any of the underlying data to Braze. Customers can also add a connected source to the Braze dashboard, allowing them to create CDI Segments that can be used to build and tailor audiences. And all of this is possible without duplicating any information from the customer's data warehouse into the Braze platform.
Even more exciting?
- CDI Segments are now available for Snowflake, Google BigQuery, Databricks, and Amazon Redshift.
Why do CDI Segments matter?
When it comes to that pool of data, prioritizing high-value data for insights, standardizing it into a consolidated source of truth, and activating it in real time for maximum impact is what provides a true competitive advantage.
To do that, brands need reliable tools to enable the use of zero- and first-party data in their customer engagement strategies. The numerous middleware layers that query and transport data from warehouses to engagement platforms can add complexity to brands’ data architecture and have the potential to introduce latency. This hinders marketers from capitalizing on real-time opportunities to engage with customers effectively and can lead to messaging that is outdated or ineffective.
That’s where CDI Segments come in. This feature helps keep brand data safe and secure, while making it easily available for marketers to build precise audience cohorts to deliver relevant experiences at scale.
The benefits of CDI Segments
1. Faster Time to Value
By reducing the need for intermediary data processing, CDI Segments can significantly cut down the time between data collection and when that data can be used to support segmentation and targeting, allowing marketers to move at the speed of customer expectations.
2. Enhanced Data Accuracy and Trust
Focusing on zero-copy and first-party data not only enhances the accuracy but also supports compliance with increasing privacy regulations. CDI Segments reduce the risks associated with data replication and unnecessary copies. Plus, storing fewer data copies reduces the impact of any data breaches and leaks, while helping to support compliance with data minimization principles.
3. Streamlined Operations
Eliminating complex data processing layers simplifies the data access process, making it easier for technical and non-technical teams to gather and utilize data efficiently, enhancing overall productivity.
4. Improved Customer Experiences
Direct access to accurate, timely data enables marketers to create more personalized, contextually relevant customer engagements. This tailored approach can foster deeper connections and enhance customer satisfaction and loyalty.
Final Thoughts
At Braze, we are committed to equipping marketers with the tools they need to meet and exceed their customers' evolving expectations. With CDI Segments, we’re helping make it easier for brands to use their data to build tangible, actionable strategies that drive meaningful engagement and substantial business growth.

Braze CDI Segments FAQs
What are Braze CDI Segments?
Cloud Data Ingestion Segments (CDI Segments) are a Braze feature that gives customers zero-copy access to information and insights held in their own data warehouses, directly from within Braze. Instead of moving warehouse data into Braze first, customers can directly query their data warehouse to create new segments, and add a connected source to the Braze dashboard so those CDI Segments can be used to build and tailor audiences duplicating any of the underlying data into the Braze platform.
What does zero-copy mean?
Zero-copy means Braze queries the data warehouse directly to build segments rather than copying or replicating the underlying data into Braze first. The data stays in its original location; Braze accesses it in place instead of ingesting a duplicate copy.
This matters for a few concrete reasons:
- Fewer data copies = better privacy posture. Reducing replication supports compliance with data minimization principles and reduces the risk associated with unnecessary duplicate copies.
- Smaller breach footprint. Storing fewer copies of the data reduces the potential impact of any data breach or leak, since there's less duplicated sensitive information sitting in additional systems.
- Less architectural complexity. It eliminates the "numerous middleware layers that query and transport data from warehouses to engagement platforms," which otherwise add complexity and can introduce latency.
Which data warehouses are supported?
CDI Segments currently support four data warehouses:
- Snowflake
- Google BigQuery
- Databricks
- Amazon Redshift
