Two-way sync
Changes in Amazon DynamoDB or Amazon Lightsail instantly reflect in both systems. No stale data, no manual imports.
Keep Amazon DynamoDB and Amazon Lightsail in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.
Stacksync syncs tables or collections between Amazon DynamoDB and Amazon Lightsail continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.
Services that own separate databases stay consistent on the records they share, without a custom replication layer.
Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.
Keep the same dataset live in both Amazon DynamoDB and Amazon Lightsail, so each workload runs on the engine that suits it.
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 DynamoDB objects | Amazon Lightsail objects | How this pairing syncs | |
|---|---|---|---|
| Tables Top-level containers, each with a partition key and optional sort key; Stacksync syncs a table as a stream of items with full read and write via PutItem, UpdateItem, and DeleteItem. | Tables Relational tables read from and written to at row level. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| DynamoDB Streams Ordered item-level change records (INSERT, MODIFY, REMOVE) with old/new image views and 24-hour retention; the native change-data-capture source Stacksync reads for near-real-time sync. | Views Query-backed read-only sources. | DynamoDB Streams is specific to Amazon DynamoDB and Views to Amazon Lightsail — each maps to any object or custom field on the other side. | |
| Global Tables Multi-region, active-active replicas of a table kept in sync by DynamoDB; each region is read and written locally with last-writer-wins conflict resolution. | Users and Grants Database accounts used to give the sync connection scoped access. | Global Tables is specific to Amazon DynamoDB and Users and Grants to Amazon Lightsail — each maps to any object or custom field on the other side. | |
| Time to Live (TTL) Per-item expiry timestamps; DynamoDB deletes expired items in the background and emits a Streams REMOVE record for each deletion. | Managed Databases Lightsail-hosted MySQL or PostgreSQL instances that a sync connects to as standard databases. | Time to Live (TTL) is specific to Amazon DynamoDB and Managed Databases to Amazon Lightsail — each maps to any object or custom field on the other side. | |
| Items Individual schemaless records (attributes up to 400 KB each); read with GetItem, Query, and Scan and written with PutItem or BatchWriteItem, so write is supported here. | Databases Logical databases on the instance that scope a connection. | Items is specific to Amazon DynamoDB and Databases to Amazon Lightsail — each maps to any object or custom field on the other side. | |
| Global secondary indexes (GSIs) Alternate key projections that let you Query by non-key attributes without a full table Scan; read-only views maintained automatically by DynamoDB. | Schemas Namespaces used when selecting tables to sync. | Global secondary indexes (GSIs) is specific to Amazon DynamoDB and Schemas to Amazon Lightsail — each maps to any object or custom field on the other side. |
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.
DetectionChanges in Amazon DynamoDB are captured at the source via change data capture — no polling loop against its API. DynamoDB Streams emit ordered item-level change records (INSERT, MODIFY, REMOVE) with KEYS_ONLY, NEW_IMAGE, OLD_IMAGE, or NEW_AND_OLD_IMAGES views.
DeliveryEach detected change is applied to Amazon Lightsail as a row-level write, with types converted between the two schemas.
DetectionStacksync polls Amazon Lightsail for changes on an incremental schedule, reading only records changed since the previous pass. Polling on timestamp or key columns.
DeliveryEach detected change is applied to Amazon DynamoDB as a row-level write, with types converted between the two schemas.
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Amazon DynamoDB–Amazon Lightsail connection.
Changes in Amazon DynamoDB or Amazon Lightsail instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Amazon DynamoDB or Amazon Lightsail data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Amazon DynamoDB or Amazon Lightsail record.
Track your Amazon DynamoDB ⇄ Amazon Lightsail sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Amazon DynamoDB and Amazon Lightsail.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Amazon DynamoDB and Amazon Lightsail with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Amazon DynamoDB and Amazon Lightsail objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Amazon DynamoDB and Amazon Lightsail: authenticate both systems, choose the objects to sync (such as Amazon DynamoDB's Tables and DynamoDB Streams), map fields visually, and changes propagate both ways in milliseconds — no code required.
Amazon DynamoDB: AWS SDK / low-level HTTPS JSON API at dynamodb.<region>.amazonaws.com (PutItem, GetItem, UpdateItem, DeleteItem, Query, Scan, BatchWriteItem, TransactWriteItems), plus PartiQL (ExecuteStatement) for SQL-style access and DynamoDB Streams for change capture. Authentication: AWS Signature Version 4 (SigV4) signed requests using an IAM access key ID and secret key, or temporary STS credentials from an assumed IAM role; IAM policies scope access down to table and item level. Amazon Lightsail: MySQL or PostgreSQL wire protocol (SQL) to the managed database endpoint. Authentication: Database credentials; public endpoint access must be enabled or a tunnel used. Stacksync manages authentication, retries, and rate limits on both sides.
Amazon DynamoDB: Throughput is metered in capacity units (provisioned or on-demand): 1 WCU = one 1 KB write/second and 1 RCU = one strongly-consistent 4 KB read/second; breaching capacity returns ProvisionedThroughputExceededException and the request is throttled. Amazon Lightsail: Lightsail targets simplified, fixed-price bundles; database configuration options are narrower than full Amazon RDS, which affects how much replication tuning is available. Stacksync's field mapping accounts for these differences between Amazon DynamoDB and Amazon Lightsail without custom code.
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Amazon DynamoDB and Amazon Lightsail records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Amazon DynamoDB and Amazon Lightsail connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Amazon DynamoDB–Amazon Lightsail integration in-house.
Yes — Stacksync ships production-grade connectors for both Amazon DynamoDB and Amazon Lightsail. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
