Why teams connect AWS S3 and Databricks

Keep tables consistent across AWS S3 and Databricks, 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 Databricks 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

  • Stage bulk loads for warehouses that ingest from object storage.
  • Archive change history from ongoing syncs as timestamped files for audit and replay.
  • Land CRM and ERP records in Delta tables continuously so lakehouse models work from current operational data.
  • Use Change Data Feed to propagate only changed rows to downstream apps instead of full-table scans.

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 Databricks

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 Databricks objects
Event Notifications Notifications on object creation or deletion that trigger incremental processing. SQL Warehouses The compute endpoint a sync connects to for query execution.
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Change Data Feed Row-level change records on Delta tables that drive incremental reads.
Multipart Uploads The mechanism used to write large export files reliably. Catalogs Top level of the Unity Catalog namespace, scoping which schemas a sync can address.
Buckets Top-level containers a sync targets; region and policy are set at this level. Schemas Group tables and views; syncs typically target a dedicated schema per source system.
Objects The stored files (CSV, JSON, Parquet); syncs read them as datasets or write exports into them. Delta Tables The primary read and write target; operational data lands here as managed or external tables.
Prefixes Key-name paths used to partition synced datasets, since S3 has no real directories. Views Curated read-only projections used as sync sources for downstream tools.

How the AWS S3 and Databricks 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

Databricks

Integration surface
SQL over JDBC/ODBC via SQL warehouses, plus a REST API including statement execution
Authentication
Personal access tokens or OAuth machine-to-machine credentials for service principals
Change detection
Delta Lake Change Data Feed for row-level changes; otherwise incremental polling on watermark columns
Capabilities
read · write · CDC
Rate limits
Throughput depends on the SQL warehouse size; API calls are subject to workspace rate limits
