CDC from Read-Only Replicas for PostgreSQL
Estuary Flow now supports CDC from PostgreSQL read-only replicas! This update enables real-time data streaming without requiring write access to your primary database, enhancing flexibility, scalability, and security for PostgreSQL users.
Change Data Capture (CDC) just got even more versatile with Estuary Flow! We’re thrilled to announce that our source-postgres connector now supports CDC from read-only replicas. This update allows you to capture real-time changes without write access to your primary database, making it a perfect fit for environments with strict permissions or high-availability requirements.
What Does This Mean for You?
Enhanced Flexibility:
You can now stream CDC data from read-only replicas, enabling secure and efficient data capture in PostgreSQL environments. This is especially useful for organizations where write access to production databases is restricted.
Simplified Setup:
No more write permissions needed for capturing CDC. With this feature, you can leverage PostgreSQL's replication architecture while maintaining the integrity and security of your primary database.
Operational Efficiency:
Reduce the load on your primary database by offloading CDC processes to read replicas. This approach minimizes impact on production systems and supports scalable data integration workflows.
Key Benefits of CDC from Read-Only Replicas
- Seamless Integration: Use read replicas to capture CDC streams without modifying your primary database.
- Enhanced Security: Operate in environments with stringent access controls by avoiding the need for write permissions.
- Improved Scalability: Distribute the workload across replicas for high-performance data streaming.
How to Get Started
Enabling CDC from read-only replicas is straightforward:
- Ensure your PostgreSQL replication setup is configured correctly, with read-only replicas accessible for Estuary Flow.
- Configure the
source-postgresconnector in Estuary Flow, pointing it to your replica. - Start capturing real-time changes effortlessly—no write permissions required!
Why This Matters
At Estuary Flow, we’re committed to making real-time data integration as accessible and low-impact as possible. This update continues our mission by expanding how organizations can securely and efficiently adopt CDC in their workflows.
