How to integrate Amazon RDS for MariaDB with PostgreSQL in 3 simple steps
Connect Amazon RDS for MariaDB as your data source
Set up a source connector for Amazon RDS for MariaDB in minutes. Estuary supports streaming (including CDC where available) and batch data capture through events, incremental syncs, or snapshots — without custom pipelines, agents, or manual configuration.
Configure PostgreSQL as your destination connector
Estuary supports intelligent schema handling, with schema inference and evolution tools that help align source and destination structures over time. It supports both batch and streaming data movement, reliably delivering data to PostgreSQL.
Deploy and Monitor Your End-to-End Data Pipeline
Launch your pipeline and monitor it from a single UI. Estuary guarantees exactly-once delivery, handles backfills and replays, and scales with your data — without engineering overhead.

Amazon RDS for MariaDB connector details
Estuary’s Amazon RDS for MariaDB connector uses Change Data Capture (CDC) via the binary log to stream real-time changes from RDS-hosted MariaDB databases into Estuary collections. Built on the same foundation as Estuary’s MySQL connector, it supports continuous replication for inserts, updates, and deletes, enabling low-latency data movement across your ecosystem.
- Continuous CDC replication using MariaDB’s binary logs
- Supports backfill + streaming for complete table capture
- Compatible with read replicas for offloading workloads
- Configurable binlog retention and recovery safeguards
- Secure connectivity through SSH tunneling or IP allowlisting, with deployment options in Estuary’s managed cloud or private BYOC environments for enhanced data control and compliance

PostgreSQL connector details
The PostgreSQL materialization connector writes Estuary collections into PostgreSQL tables and keeps them updated continuously as source data changes. Estuary creates and manages destination tables for each selected collection, applies ongoing inserts, updates, and deletes, and maintains schema consistency so PostgreSQL can serve real-time application, reporting, and operational workloads.
- Materialize Estuary collections into PostgreSQL tables with low-latency, incremental updates.
- Create and manage destination tables automatically based on your selected Estuary collections.
- Apply inserts, updates, and deletes so PostgreSQL stays current with upstream source changes.
- Connect using your PostgreSQL host, port, database name, schema, and database user credentials.
- Use port 5432 by default when no custom port is specified.
- Support self-hosted PostgreSQL, Amazon RDS, Amazon Aurora, Google Cloud SQL, Azure Database for PostgreSQL, and Supabase.
- Use SSL, SSH tunneling, or cloud IAM authentication where supported for secure connectivity.
- Handle schema evolution, table naming, and reserved words during materialization.

Frequently Asked Questions
Is this integration suitable for production workloads?
Yes. Estuary pipelines are designed for production use, with exactly-once delivery semantics, automated backfills, and continuous operation at scale.
Can I control where my data runs and is processed?
Yes. Estuary offers multiple deployment options, including fully managed SaaS, private deployments, and bring-your-own-cloud (BYOC). This allows teams to control where their data plane runs and meet security, compliance, and networking requirements. Learn more about Estuary's security and deployment options.
Can I build this Amazon RDS for MariaDB to PostgreSQL integration manually?
Yes, it's possible to build a manual pipeline using custom scripts, scheduled jobs, or open-source tools. However, manual approaches typically require ongoing maintenance, custom error handling, schema management, and operational overhead. Estuary simplifies this by providing a managed pipeline with built-in reliability, scaling, and monitoring.
