Alloy DB for Postgres connector details
The AlloyDB connector for Estuary Flow uses change data capture (CDC) to replicate inserts, updates, and deletes from your AlloyDB database into Flow collections in near real time. Built on the PostgreSQL capture foundation, it brings AlloyDB’s scalability and Google Cloud integration into the Estuary ecosystem with minimal setup effort.
- Continuously streams row-level changes from AlloyDB using PostgreSQL logical replication
- Supports automatic creation of replication slots, publications, and watermark tables
- Requires SSH tunneling for secure access, since AlloyDB doesn’t support IP allowlisting
- Configurable backfill behavior to balance completeness and performance
- Enterprise-ready: Compatible with Estuary’s Private and BYOC deployments for secure, compliant data movement

PostgreSQL connector details
Optimized for analytical and transactional workloads, the Estuary PostgreSQL connector materializes Flow collections into tables within PostgreSQL databases in real time. It creates and manages tables automatically, ensuring low-latency writes and schema consistency. The connector supports self-hosted, RDS, Aurora, Cloud SQL, Azure Database for PostgreSQL, and Supabase, with secure connectivity through SSL or SSH tunneling.
- Real-time data materialization into PostgreSQL tables
- Works with managed and on-prem PostgreSQL environments
- Supports delta updates and schema management
- Automatically handles table creation and reserved words
- Secure connections via SSL and SSH
