Efficient change data capture without the headaches
Capture every change with exactly-once delivery, schema evolution, and multi-system replication.
Real-world use cases
Real-time cross-database replication
Powering microservices with clean event logs
Streaming changes to analytics or warehouses
Connect to the databases that matter most
Estuary captures inserts, updates, and deletes directly from production databases using log-based change data capture, without impacting application performance.
How log-based CDC works
Why it matters
Your source systems stay fast. Log-based CDC captures every change without adding load to production databases.
Your data stays fresh. Analytics, operations, and ML models always have what they need to keep pace with the business.
Your deployments stay compliant. Deterministic recovery and full schema evolution mean less manual intervention and more confidence at scale.
CDC capabilities
Log-based CDC
Continuously replicate with log-based CDC from Postgres, MySQL, MongoDB, Oracle, SQL Server, and more with exactly-once delivery guarantees.
Schema evolution
Schema changes are automatic. No pipeline breaks, no manual updates required.
Multi target replication
One source, many destinations: warehouses, search indexes, microservices, and streaming systems simultaneously.
How we do CDC differently
Built on Gazette for high throughput and durability
Deterministic recovery even during failure events
Schema propagation across all downstream systems
Replay logic to repair or reprocess change streams
Read Full Success Story“We're a big fan of Estuary's real-time, no code model. It's magic that we're getting real time data without much effort and we don't have to spend time thinking about broken pipelines. We've also experienced fantastic support by Estuary.”
CDC that works the way your database does, at the speed your business needs.
Frequently asked questions
Does CDC impact database performance?
No. Estuary uses log-based CDC, which reads from database logs rather than querying tables, minimizing impact on production systems.
What databases does Estuary support?
Estuary supports major databases including Postgres, MySQL, MongoDB, Oracle, and SQL Server, among others.
Can I replicate data to multiple destinations at once?
Yes. Estuary allows one-to-many replication, so a single source can feed warehouses, search systems, microservices, and AI pipelines simultaneously.
How does Estuary handle schema changes?
Schema evolution is automatic, meaning pipelines continue running without manual updates when your data structure changes.
