Why teams connect Amazon S3 and Rockset

Bridge query-ready tables and stored files: Rockset and Amazon S3 keep the same records in step, in real time, in both directions.

Rockset keeps the tables and query results a business reports on; Amazon S3 keeps the raw files, documents, and objects that the same business produces and shares. The two overlap wherever a dataset lives as both — a file dropped in Amazon S3 that has to become rows in Rockset, or a result in Rockset that people downstream need back as a file in Amazon S3. When that overlap is bridged by manual export and import or an overnight job, one side spends the day working from a stale copy.

Stacksync syncs Workspaces, Query Lambdas, Aliases, Integrations in Rockset with Object tags, Object versions, Prefixes (folders), Multipart uploads in Amazon S3 field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Power in-app search and filtering over synced operational data using SQL over REST.
  • 02 Serve real-time dashboards over CRM and ERP records synced from operational databases.
  • 03 Trigger a database or ERP record update the moment an S3 Event Notification fires an object-created event, for example when a partner drops an EDI or invoice file into an inbound prefix.
  • 04 Reconcile Object versions and delete markers into an audit table so teams track when files under a compliance prefix were added, replaced, or removed.

Common sync patterns

Where Amazon S3 holds the file inventory: make it queryable

The catalog of documents, owners, and folders in Amazon S3 appears as Workspaces, Query Lambdas, Aliases, Integrations in Rockset, so file metadata can be joined against the rest of your data and reported on.

Where Rockset computes the labels: push them onto the files

Classifications, scores, or status derived in Rockset are written back onto the matching Object tags, Object versions, Prefixes (folders), Multipart uploads in Amazon S3 as metadata or tags, so the file store reflects what analytics decided.

Where Amazon S3 receives the raw files: land them as query-ready rows

Files and exports that arrive in Amazon S3 are parsed into Workspaces, Query Lambdas, Aliases, Integrations in Rockset as they land, so analysts query current data instead of waiting on the next scheduled load.

What you can sync between Amazon S3 and Rockset

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.

Amazon S3 objects Rockset objects How this pairing syncs
Multipart uploads In-progress large-object uploads assembled from parts; objects above ~100 MB (required above 5 GB) are written this way, and incomplete uploads persist until completed or aborted. Virtual Instances Isolated compute units that separate ingest from query workloads. Multipart uploads is specific to Amazon S3 and Virtual Instances to Rockset — each maps to any object or custom field on the other side.
Buckets Top-level, region-scoped containers that hold objects; enumerated to discover the namespaces and prefixes a sync should cover. Collections Schemaless document containers that ingested and synced records land in. Buckets is specific to Amazon S3 and Collections to Rockset — each maps to any object or custom field on the other side.
Objects Files stored under a key; content is read with GET and written with PUT, and each object's key/size/ETag/LastModified is the unit indexed into a database. Documents JSON records addressable by _id, written via the Write API in sync pipelines. Objects is specific to Amazon S3 and Documents to Rockset — each maps to any object or custom field on the other side.
Object metadata System metadata (Content-Type, size, ETag, LastModified) plus user-defined x-amz-meta-* headers; user metadata is fixed at write time and only changeable by rewriting the object. Workspaces Namespaces that group collections and query lambdas per team or environment. Object metadata is specific to Amazon S3 and Workspaces to Rockset — each maps to any object or custom field on the other side.
Object tags Up to 10 key-value tags per object, mutable in place via the tagging API independent of content, so classification and retention labels sync two-way without rewriting files. Query Lambdas Named, parameterized SQL queries invoked over REST to read synced data. Object tags is specific to Amazon S3 and Query Lambdas to Rockset — each maps to any object or custom field on the other side.
Object versions When bucket versioning is enabled every write creates a new version ID; prior versions and delete markers are readable for history and audit syncs. Aliases Stable names that point at collections, used to swap datasets without changing queries. Object versions is specific to Amazon S3 and Aliases to Rockset — each maps to any object or custom field on the other side.

How changes propagate between Amazon S3 and Rockset

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Amazon S3 Rockset Sub-second propagation

DetectionAmazon S3 notifies Stacksync of record changes through webhook events. S3 Event Notifications push object-created, object-removed, and object-tagging events to SNS, SQS, Lambda, or EventBridge.

DeliveryEach detected change is applied to Rockset as a row-level write, with types converted between the two schemas.

Rockset Amazon S3 Interval-based propagation

DetectionStacksync polls Rockset for changes on an incremental schedule, reading only records changed since the previous pass. Polling via SQL queries on timestamp fields.

DeliveryEach detected change is written to Amazon S3 through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Amazon S3: S3 sustains at least 3,500 PUT/COPY/POST/DELETE and 5,500 GET/HEAD requests per second per partitioned prefix and scales higher automatically; bursts can return HTTP 503 SlowDown while it repartitions.

How the Amazon S3 and Rockset connectors work

Amazon S3

Integration surface
S3 REST API (also via AWS SDKs and the S3-compatible endpoint)
Authentication
AWS IAM credentials — an access key ID and secret access key signed with AWS Signature Version 4; supports temporary STS credentials and cross-account IAM roles
Change detection
S3 Event Notifications push object-created, object-removed, and object-tagging events to SNS, SQS, Lambda, or EventBridge; there is no modified-since query, so polling relies on each object's LastModified from ListObjectsV2
