Why teams connect Dynamo DB and Elasticsearch

Keep Dynamo DB and Elasticsearch 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 Elasticsearch 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.
  • Mirror support tickets into an index used for full-text search and agent-assist tooling.
  • Feed enriched customer records into an index used for vector or hybrid search in AI applications.

Cross-engine sync

Keep the same dataset live in both Dynamo DB and Elasticsearch, 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.

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

What you can sync between Dynamo DB and Elasticsearch

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 Elasticsearch objects
Attributes Per-item fields, including nested maps and lists, flattened or mapped during sync. Documents The unit of sync; JSON records created, updated, and deleted by _id.
Partition and Sort Keys The primary key pair used as the match key for bi-directional sync. Index mappings Field type definitions that determine how synced fields are indexed and queried.
Global Secondary Indexes Alternate access paths used when sync queries filter on non-key attributes. Aliases Stable read/write names that let a sync cut over between index versions without downtime.
DynamoDB Streams Ordered item-level change records consumed for incremental sync. Data streams Append-only targets for time-series or event data pushed from source systems.
Global Tables Multi-region replicas relevant when syncs must read from a specific region. Ingest pipelines Server-side transforms applied to documents as a sync writes them.
Tables The top-level containers a sync targets; each table is addressed independently. Index templates Reusable settings and mappings applied automatically to new indices a sync creates.
What ships with Dynamo DB ⇄ Elasticsearch

No-code + pro-code

Workflow automation

Trigger automated workflows whenever Dynamo DB or Elasticsearch 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 Elasticsearch record.

Observability

Monitoring

Track your Dynamo DB ⇄ Elasticsearch 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 Elasticsearch.

How the Dynamo DB and Elasticsearch 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

Elasticsearch

Integration surface
REST API (JSON over HTTP)
Authentication
API keys or basic authentication; Elastic Cloud also issues service account tokens
Change detection
Polling on timestamp or sequence fields; Elasticsearch does not expose a native change feed or webhooks
Capabilities
read · write
Rate limits
No fixed request quota; throughput is bounded by cluster sizing, thread pools, and bulk queue capacity
How it works

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

    Choose tables

    Pick the Dynamo DB and Elasticsearch 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.
