Why teams connect Amazon RDS and BigQuery

Connect Amazon RDS and BigQuery with one live, two-way sync: operational rows flow into the warehouse, and computed results flow back where systems can read them fast.

Operational databases and analytical warehouses want the same data at different moments. Analysts want Amazon RDS's rows in BigQuery, current and joinable, without a change-data-capture pipeline to maintain. Engineers want the outputs of warehouse work, such as aggregates, features, and segments, available in Amazon RDS where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in Amazon RDS sync into BigQuery in real time, and result tables in BigQuery sync back into Amazon RDS, with schema and type mapping between the two systems handled for you.

Common use cases

  • Feed ML feature tables in BigQuery from operational systems on a continuous schedule
  • Land CRM and ERP records in BigQuery continuously so dashboards reflect business systems without nightly batch jobs
  • Mirror SaaS objects into RDS tables so product features can join business data with application data in one query
  • Keep an RDS reporting database hydrated from operational tools without maintaining ETL jobs

Offload heavy reads

Point analytical queries at the synced copy in BigQuery and keep Amazon RDS focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from Amazon RDS land in BigQuery as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in BigQuery sync into Amazon RDS, where whatever reads from that database gets them without querying the warehouse.

What you can sync between Amazon RDS and BigQuery

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Amazon RDS objects BigQuery objects
Schemas Namespaces within a database used to isolate synced tables. Datasets Organizational container — you pick which dataset’s tables to sync.
Tables The core sync target; rows map to records in connected SaaS systems. Projects Connection scope: the service account grants access per project.
Views Read-side projections exposed to outbound syncs. Tables The syncable unit: only tables can be synced per the Stacksync docs.
Columns Field-level mapping targets, typed per the underlying engine. Partitioned tables Synced like regular tables; partition columns map to target fields.
Primary and Unique Keys Match keys for idempotent upserts. Clustered tables Supported; clustering is transparent to the sync.

How the Amazon RDS and BigQuery connectors work

Amazon RDS

Integration surface
SQL wire protocol of the chosen engine (PostgreSQL, MySQL, MariaDB, SQL Server, Oracle)
Authentication
Database credentials over SSL/TLS, or IAM database authentication on supported engines
Change detection
Engine-native log-based CDC: MySQL/MariaDB binlog, PostgreSQL logical replication, SQL Server CDC; enabled through RDS parameter groups, with polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput depends on instance class, storage IOPS, and connection limits

BigQuery

Integration surface
GoogleSQL via the BigQuery REST API, client libraries, JDBC/ODBC drivers, and the Storage Read/Write APIs
Authentication
Google Cloud service account: create a dedicated service account, grant roles (BigQuery Data Editor, BigQuery Job User, Cloud Functions Service Agent, Cloud Run Developer, Eventarc Event Receiver
Change detection
Real-time notification service deployed into your Google Cloud project: Eventarc ("a notification service that enables real-time updates to happen") with a Cloud Run "secure portal for real-time notification service in
Capabilities
read · write · CDC
Rate limits
Subject to Google Cloud quotas on queries, DML, and streaming; DML is supported but the platform favors append-heavy batch and streaming loads over row-at-a-time writes
