Why teams connect AWS S3 and StarRocks

Keep tables consistent across AWS S3 and StarRocks, for a migration, a multi-warehouse stack, or a dataset two platforms both need.

Companies end up with two warehouses for practical reasons: a migration in progress, teams that standardized on different platforms, an acquisition, or tools that only connect to one of them. The result is the same dataset maintained twice, with duplicated pipelines and numbers that almost match.

Stacksync syncs tables between AWS S3 and StarRocks continuously, in either or both directions. Rows changed on one platform appear on the other within seconds, with schema and type mapping handled, so both warehouses answer questions with the same data.

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.
  • Consolidate several sources into StarRocks as the query layer while Stacksync handles movement
  • Land CRM and ERP records into StarRocks to serve low-latency operational dashboards

Shared datasets across teams

Where different teams run different warehouses, sync the curated tables both rely on so their metrics agree by construction.

Consolidation after M&A

Bring the acquired company's warehouse data across continuously instead of through one-off dumps.

Migration without a big bang

When one platform is replacing the other, keep tables mirrored while workloads move over gradually, and cut over with nothing to backfill.

What you can sync between AWS S3 and StarRocks

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 StarRocks objects
Objects The stored files (CSV, JSON, Parquet); syncs read them as datasets or write exports into them. Materialized views Automatically maintained rollups used to accelerate queries on synced data.
Prefixes Key-name paths used to partition synced datasets, since S3 has no real directories. Views Logical views for shaping analytical reads.
Object Metadata System and user-defined metadata read alongside object contents. Partitions Time or range partitions that scope loads and retention.
Object Versions Prior copies retained when versioning is enabled, relevant for reprocessing. Columns Columnar storage with types mapped from source systems during sync.
Event Notifications Notifications on object creation or deletion that trigger incremental processing. Databases Top-level namespaces addressed exactly as in MySQL clients.
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Tables Defined with a table model (Primary Key, Unique Key, Aggregate, Duplicate Key) that determines update behavior.

How the AWS S3 and StarRocks 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

StarRocks

Integration surface
MySQL wire protocol for SQL; HTTP-based Stream Load API for ingestion
Authentication
Database credentials (MySQL-compatible username/password)
Change detection
Query-based polling when reading; StarRocks is most often the destination side of a sync
Capabilities
read · write
Rate limits
Ingestion throughput is bounded by cluster resources rather than API quotas
