Why teams connect Apache Cassandra and Dynamo DB

Keep Apache Cassandra and Dynamo DB 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 Apache Cassandra and Dynamo DB 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 profile data between Cassandra and a CRM so operational apps and sales tools agree.
  • Write attributes computed elsewhere (scores, preferences) back into Cassandra tables serving low-latency reads.
  • Consolidate multi-region Global Tables data into a single reporting store.
  • Replace ad-hoc export scripts with continuous sync driven by DynamoDB Streams.

Cross-engine sync

Keep the same dataset live in both Apache Cassandra and Dynamo DB, 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 Apache Cassandra and Dynamo DB

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.

Apache Cassandra objects Dynamo DB objects
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Partition and Sort Keys The primary key pair used as the match key for bi-directional sync.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Global Secondary Indexes Alternate access paths used when sync queries filter on non-key attributes.
Collections List, set, and map columns handled with type-aware field mapping. DynamoDB Streams Ordered item-level change records consumed for incremental sync.
Counters Increment-only counter columns, usually read-only in syncs. Global Tables Multi-region replicas relevant when syncs must read from a specific region.
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Tables The top-level containers a sync targets; each table is addressed independently.
Tables Wide-column tables addressed by partition key, the unit of row-level sync. Items Schemaless records keyed by partition (and optional sort) key, mapped to rows or SaaS objects in syncs.

Rate limits
No API quotas; throughput is governed by cluster capacity and consistency-level choices

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
How it works

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