Supabase connector details
The Supabase connector materializes Estuary collections into tables within a Supabase PostgreSQL database, enabling fast, reliable delivery of right-time data to your applications and analytics environment.
- Direct integration: Writes Estuary collections straight to Supabase-hosted PostgreSQL tables, automatically managing schema creation and updates.
- Secure connection: Uses Supabase’s direct database address (not the pooler) for stable, transaction-safe writes and prepared statements.
- Flexible updates: Supports both standard (merge) and delta update modes for efficient data application.
- Simple authentication: Configure quickly with your Supabase credentials and optional SSL settings.
- Optimized for developers: Ideal for teams using Supabase as their real-time backend or cloud data warehouse.
💡 Data freshness: Right-time delivery (incremental updates as Estuary transactions complete) — built for always-current app and analytics pipelines.
