Why teams connect Dynamo DB and OpenSearch

Keep Dynamo DB and OpenSearch synchronized in real time, across engines, regions, or services, in one or both directions.

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 Dynamo DB and OpenSearch 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.

Common use cases

  • Sync customer records between DynamoDB-backed services and a CRM so support and sales see live application state.
  • Mirror SaaS objects into DynamoDB items to serve low-latency lookups from production services.
  • Index support tickets and activity logs from SaaS tools for operational dashboards.
  • Backfill or rebuild indexes from a database after mapping changes without hand-written ETL.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

Cross-engine sync

Keep the same dataset live in both Dynamo DB and OpenSearch, so each workload runs on the engine that suits it.

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

What you can sync between Dynamo DB and OpenSearch

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.

Dynamo DB objects OpenSearch objects
Attributes Per-item fields, including nested maps and lists, flattened or mapped during sync. Ingest pipelines Server-side processors that transform documents as they are written
Partition and Sort Keys The primary key pair used as the match key for bi-directional sync. Data streams Append-oriented time-series storage for logs and events pushed from source systems
Global Secondary Indexes Alternate access paths used when sync queries filter on non-key attributes. Snapshots Backup artifacts, relevant when reseeding an index from a repository
DynamoDB Streams Ordered item-level change records consumed for incremental sync. Indexes The core container; synced records land in indexes with defined mappings
Global Tables Multi-region replicas relevant when syncs must read from a specific region. Documents JSON records written via the index and bulk APIs and read via search queries
Tables The top-level containers a sync targets; each table is addressed independently. Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills
What ships with Dynamo DB ⇄ OpenSearch

Trigger automated workflows whenever Dynamo DB or OpenSearch data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single Dynamo DB or OpenSearch record.

Observability

Monitoring

Track your Dynamo DB ⇄ OpenSearch sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between Dynamo DB and OpenSearch.

How the Dynamo DB and OpenSearch connectors work

Dynamo DB

Integration surface
Proprietary JSON-over-HTTPS API accessed through AWS SDKs; PartiQL supported for SQL-like queries
Authentication
AWS IAM credentials with SigV4 request signing
Change detection
Item-level change streams via DynamoDB Streams or Kinesis Data Streams integration
Capabilities
read · write · CDC
Rate limits
Throughput is governed by the table's provisioned or on-demand capacity mode

OpenSearch

Integration surface
REST API over HTTP(S) with JSON payloads
Authentication
basic authentication with the security plugin, or AWS IAM request signing on Amazon OpenSearch Service
Change detection
no native change feed; reads rely on queries with scroll or point-in-time polling
Capabilities
read · write
Rate limits
throughput bounded by cluster sizing rather than fixed API quotas
How it works

How to connect Dynamo DB to OpenSearch — three steps, no code

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.

  1. 01

    Connect your apps

    Authenticate Dynamo DB and OpenSearch with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
