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 Flow 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

Amazon S3 Iceberg (delta updates) connector details
This connector materializes Flow collections into Apache Iceberg tables stored in Amazon S3. It batches delta updates inside Flow, converts them to Parquet files, and appends them to Iceberg tables on a schedule you configure, making it efficient for near real-time CDC-style updates.
- Materializes Flow collections into Iceberg tables on Amazon S3
- Designed for delta updates, enabling low-latency CDC replication
- Compatible with AWS Glue or Iceberg REST Catalogs for metadata management
- Configurable upload intervals to balance freshness and cost
- Supports Iceberg V2 column types for flexible schema handling
