Why teams connect AWS S3 and Oracle DB

Connect Oracle DB 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 Oracle DB'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 Oracle DB where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in Oracle DB sync into AWS S3 in real time, and result tables in AWS S3 sync back into Oracle DB, 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.
  • Keep legacy Oracle applications running while newer services read and write the same data through a synced copy.
  • Write changes from SaaS apps back into Oracle so PL/SQL jobs and reports run on current data.

Offload heavy reads

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

Operational data in the warehouse, minus the pipeline

Rows from Oracle DB land in AWS S3 as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

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

What you can sync between AWS S3 and Oracle DB

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 S3 objects Oracle DB objects
Object Metadata System and user-defined metadata read alongside object contents. Views Curated read-only projections exposed to downstream consumers
Object Versions Prior copies retained when versioning is enabled, relevant for reprocessing. Materialized views Precomputed results occasionally used as stable replication sources
Event Notifications Notifications on object creation or deletion that trigger incremental processing. Schemas Per-user namespaces that scope sync permissions and object visibility
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Sequences Key generators to respect when external systems insert rows
Multipart Uploads The mechanism used to write large export files reliably. PL/SQL procedures and packages In-database logic that can consume or transform synced data
Buckets Top-level containers a sync targets; region and policy are set at this level. Partitions Physical subdivisions relevant when replicating high-volume tables

How the AWS S3 and Oracle DB connectors work

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

Oracle DB

Integration surface
SQL wire protocol (Oracle Net) via JDBC, ODBC, and native OCI drivers
Authentication
database username and password; wallets, Kerberos, and directory-based authentication in enterprise setups
Change detection
log-based CDC from redo logs via LogMiner or GoldenGate, or trigger and timestamp polling
Capabilities
read · write · CDC
Rate limits
throughput bounded by database resources rather than API quotas
How it works
