How to integrate Amazon RDS for MySQL with Google Spanner in 3 simple steps
- 1
Connect Amazon RDS for MySQL as your data source
Set up a source connector for Amazon RDS for MySQL 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 Google Spanner 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 Google Spanner.
- 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.

Amazon RDS for MySQL connector details
Estuary’s Amazon RDS for MySQL connector enables continuous, real-time replication from MySQL databases hosted on Amazon RDS using Change Data Capture (CDC) via the binary log. It automatically captures and streams inserts, updates, and deletes to Estuary collections, keeping your downstream systems perfectly in sync without manual intervention.
- Streams data changes in real time through MySQL binary logs
- Handles initial backfills and ongoing incremental updates seamlessly
- Compatible with RDS read replicas for performance optimization
- Supports customizable binlog retention for reliability and recovery
- Offers secure connectivity options (SSH tunneling, VPC rules) and flexible deployment in Estuary’s managed cloud or your private BYOC environment

Google Spanner connector details
The Google Spanner materialization connector in Estuary delivers data from Estuary collections into tables in a Google Spanner database. It supports continuous materialization from real-time or batch pipelines and provides controls for table configuration, delete handling, and efficient key distribution.
- Materializes Estuary collections directly into Google Spanner tables
- Standard updates to keep destination records synchronized with Estuary collections
- Optional hard deletes so records deleted upstream can also be removed from Google Spanner
- Soft deletes by default, represented through
_meta/op - Configurable destination table names for individual bindings
- Alternative schema support for bindings that should use a non-default schema
- Custom SQL during table creation for additional table-level configuration
- Google Cloud service account authentication
- Built-in key distribution optimization that adds a hash prefix to table keys to distribute writes across Spanner splits and reduce hotspots
- Option to exclude the root Flow document from standard updates for advanced use cases
The connector’s key-distribution optimization is enabled by default to spread writes across Google Spanner splits and avoid concentrated write hotspots. It can be disabled through advanced configuration when the original key ordering is preferred.

Can I build this Amazon RDS for MySQL to Google Spanner 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.
