How to integrate PostgreSQL with MariaDB in 3 simple steps

1

Connect PostgreSQL as your data source

Set up a source connector for PostgreSQL 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.

2

Configure MariaDB 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 MariaDB.

3

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.

PostgreSQL connector details

Built for real-time data integration, the Estuary PostgreSQL connector streams inserts, updates, and deletes from PostgreSQL databases using Change Data Capture (CDC) via logical replication. It reads directly from the write-ahead log (WAL) to deliver low-latency, exactly-once data movement into Flow collections. The connector supports self-hosted, RDS, Aurora, Cloud SQL, Azure Database for PostgreSQL, and Supabase, with secure connectivity options such as SSH tunneling and SSL.

  • Continuous CDC streaming through PostgreSQL logical replication
  • Works with managed and on-prem PostgreSQL instances
  • Supports backfill and read-only captures
  • Automatically manages replication slots and publications
  • Secure setup via SSH or SSL

MariaDB connector details

The MariaDB materialization connector in Estuary delivers data from your pipelines directly into your destination system — continuously and in real time. Using merge-based writes, Estuary efficiently updates only changed records, ensuring your destination stays perfectly in sync without unnecessary reprocessing. Whether for analytics, AI, or operational use cases, Estuary provides a reliable, cost-efficient way to keep MariaDB up to date.
  • Merge-based materializations to sync only what's changed
  • Low-latency delivery from streaming and batch sources
  • Automatic schema alignment so your destination matches your pipeline's evolving data
  • Flexible deployment models, including BYOC and hybrid for enterprise governance
  • Unified streaming + batch outputs in a single tool
  • End-to-end security and compliance for sensitive data workloads

    Estuary is our preferred CDC solution for importing data from application databases into BigQuery for analytics. It offers a transparent pricing structure, timely support responses, and an intuitive CLI tool for bulk configuration tasks. In contrast, other market solutions often have ambiguous pricing and fewer options for precise data replication across environments. This makes choosing to use Estuary an obvious decision.

    Frequently Asked Questions

      How is pricing calculated for moving data from PostgreSQL to MariaDB?

      Pricing is based on the volume of data moved and the number of active connectors. Use the pricing estimator above to see an estimated monthly cost for your PostgreSQL to MariaDB pipeline.

      Yes. Estuary pipelines are designed for production use, with exactly-once delivery semantics, automated backfills, and continuous operation at scale.

      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.

      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.
