Alloy DB for Postgres connector details

The AlloyDB materialization connector continuously writes data from Estuary Flow collections into AlloyDB tables, allowing you to keep a fully managed, PostgreSQL-compatible database in Google Cloud up to date with your real-time data streams.

  • PostgreSQL-compatible: Built on Estuary’s PostgreSQL connector, providing identical configuration and behavior
  • Secure connectivity: Uses SSH tunneling to connect to AlloyDB instances (since IP allowlisting isn’t supported)
  • Automatic table creation: Flow creates and manages target tables automatically based on your collection schemas
  • Delta or merge updates: Supports both incremental (delta) and standard merge-based updates
  • Ideal for analytics and applications: Perfect for workloads that need transactional consistency and scalable cloud performance

💡 Tip: Configure your SSH bastion VM within the same Google Cloud project as your AlloyDB instance for secure, low-latency connections.
