Why teams connect AWS Aurora MySQL and AWS S3

Connect AWS Aurora MySQL and AWS S3 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 AWS Aurora MySQL's rows in AWS S3, 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 AWS Aurora MySQL where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in AWS Aurora MySQL sync into AWS S3 in real time, and result tables in AWS S3 sync back into AWS Aurora MySQL, with schema and type mapping between the two systems handled for you.

Common use cases

  • Export synced operational data to S3 as files feeding a data lake or downstream batch jobs.
  • Trigger incremental sync runs from S3 event notifications when new files land in a prefix.
  • Stream row changes from Aurora into SaaS tools via binlog CDC instead of scheduled batch exports.
  • Sync a production Aurora cluster with an analytics database while filtering out sensitive columns.

Serve warehouse results at database speed

Aggregates or model outputs computed in AWS S3 sync into AWS Aurora MySQL, where whatever reads from that database gets them without querying the warehouse.

Fresh analytics without loading windows

Because changes stream continuously, analysts query current data instead of waiting for last night's load.

Offload heavy reads

Point analytical queries at the synced copy in AWS S3 and keep AWS Aurora MySQL focused on its operational workload.

What you can sync between AWS Aurora MySQL and AWS S3

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.

AWS Aurora MySQL objects AWS S3 objects
Databases (schemas) Logical namespaces that scope which tables a sync connection can see. Object Versions Prior copies retained when versioning is enabled, relevant for reprocessing.
Tables The primary sync unit; each table maps one-to-one to a table or object in the paired system. Event Notifications Notifications on object creation or deletion that trigger incremental processing.
Rows Inserted, updated, and deleted individually or in bulk during two-way syncs. Access Points Scoped network endpoints used to grant a sync narrow access to a bucket.
Columns MySQL data types are mapped to the paired system's field types during schema setup. Multipart Uploads The mechanism used to write large export files reliably.
Primary keys and indexes Used to match rows across systems and keep incremental syncs efficient. Buckets Top-level containers a sync targets; region and policy are set at this level.
Views Can serve as read-only sync sources for derived or filtered datasets. Objects The stored files (CSV, JSON, Parquet); syncs read them as datasets or write exports into them.

How the AWS Aurora MySQL and AWS S3 connectors work

AWS Aurora MySQL

Integration surface
SQL wire protocol (MySQL-compatible), standard MySQL drivers and JDBC
Authentication
Database credentials, optionally AWS IAM database authentication, over TLS
Change detection
Log-based CDC via the MySQL binary log (binlog), with polling on timestamp columns as a fallback
Capabilities
read · write · CDC

AWS S3

Integration surface
REST API (the S3 API), accessed directly or through AWS SDKs
Authentication
AWS IAM credentials with SigV4 signing; commonly a role scoped to specific buckets and prefixes
Change detection
S3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge; list-based polling as a fallback
Capabilities
read · write · webhooks
Rate limits
Request throughput scales per prefix; sustained high-volume workloads should spread keys across prefixes
