Why teams connect AWS S3 and YugabyteDB

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

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

Common use cases

  • Stage bulk loads for warehouses that ingest from object storage.
  • Archive change history from ongoing syncs as timestamped files for audit and replay.
  • Run log-based CDC from YugabyteDB tables into a warehouse for analytics without batch dumps.
  • Two-way sync between YugabyteDB application tables and a CRM so product data and account records stay consistent.

Operational data in the warehouse, minus the pipeline

Rows from YugabyteDB 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 YugabyteDB, 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.

What you can sync between AWS S3 and YugabyteDB

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 YugabyteDB objects
Prefixes Key-name paths used to partition synced datasets, since S3 has no real directories. Tables Distributed SQL tables split into tablets; the primary read and write targets.
Object Metadata System and user-defined metadata read alongside object contents. Indexes Global secondary indexes maintained transactionally alongside table writes.
Object Versions Prior copies retained when versioning is enabled, relevant for reprocessing. Materialized Views Precomputed query results available in YSQL for read-side shaping.
Event Notifications Notifications on object creation or deletion that trigger incremental processing. Schemas Postgres-style namespaces in YSQL used to organize synced data.
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Sequences ID generation objects relevant when syncing writes into YSQL tables.
Multipart Uploads The mechanism used to write large export files reliably. CDC Streams Change streams over the storage-layer WAL consumed through logical replication or Debezium-compatible connectors.

How the AWS S3 and YugabyteDB 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

YugabyteDB

Integration surface
SQL wire protocol (PostgreSQL-compatible YSQL) plus a Cassandra-compatible YCQL API
Authentication
Database credentials
Change detection
Native CDC from the write-ahead log via PostgreSQL logical replication or Debezium-compatible connectors
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput scales with cluster nodes and tablet distribution.
