# CDC from Read-Only Replicas for PostgreSQL

Estuary 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.

## 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:

1. Ensure your PostgreSQL replication setup is configured correctly, with read-only replicas accessible for Estuary.
2. Configure the `source-postgres` connector in Estuary, pointing it to your replica.
3. Start capturing real-time changes effortlessly—no write permissions required!

## Why This Matters

At Estuary, 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.
