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

Amazon S3 CSV connector details
The Amazon S3 CSV connector exports Flow collection data as compressed CSV files into your S3 bucket, offering a reliable and scalable way to persist real-time updates in an analytics-friendly format.
- Delta-based materialization: Writes only changed records (delta updates) from Flow collections as CSV files, efficiently keeping your data lake up to date.
- Configurable batching: Aggregates changes in Flow and uploads them to S3 at a defined interval, with support for custom file size limits.
- Flexible authentication: Supports both AWS access keys and IAM roles for secure access management.
- Structured file naming: Automatically organizes files with versioned, lexically sortable naming for easy tracking and replay.
- Customizable storage paths: Lets you define prefixes and per-collection paths for better data organization.
- Compatible and extensible: Can also connect to S3-compatible APIs using a custom endpoint if needed.
💡 Tip: Use shorter upload intervals for near-real-time analytics, or increase them to reduce storage and API costs when dealing with large batch updates.
