Why teams connect Amazon Aurora and Couchbase

Keep Amazon Aurora and Couchbase 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 Amazon Aurora and Couchbase 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

  • Stream row-level changes from Aurora into a warehouse for near-real-time analytics without batch exports.
  • Consolidate several Aurora clusters into one reporting database.
  • Consolidate documents from multiple Couchbase clusters into a single analytical store.
  • Write cleaned or enriched records from operational databases back into Couchbase collections that applications read.

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 Amazon Aurora and Couchbase, 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 Amazon Aurora and Couchbase

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 Aurora objects Couchbase objects
Views Read-only query-backed sources for downstream syncs. Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient.
Materialized Views Precomputed result sets (PostgreSQL-compatible clusters) readable as sources. XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster.
Columns and Data Types Standard MySQL or PostgreSQL types mapped during field mapping. Full-text search indexes Search indexes over documents, relevant when syncing searchable content.
Primary and Foreign Keys Constraints used to identify records and preserve relational integrity in syncs. Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas.
Read Replicas Reader endpoints that syncs can target to keep load off the writer. Scopes Namespaces inside a bucket used to group collections, similar to schemas.
Databases Logical databases within a cluster that scope a sync connection. Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables.

How the Amazon Aurora and Couchbase connectors work

Amazon Aurora

Integration surface
MySQL or PostgreSQL wire protocol (SQL); optional RDS Data API over HTTPS
Authentication
Database credentials or IAM database authentication
Change detection
Log-based CDC: binlog on MySQL-compatible clusters, logical replication/decoding on PostgreSQL-compatible clusters; polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits for wire-protocol access; throughput is bounded by instance class and connection limits

Couchbase

Integration surface
SQL++ (N1QL) query service, key-value SDK APIs, and REST management APIs
Authentication
Database credentials with role-based access control, typically over TLS
Change detection
Database Change Protocol (DCP) streams document mutations; SQL++ polling on document fields as an alternative
Capabilities
read · write · CDC
Rate limits
Throughput is bounded by cluster sizing rather than API rate limits
How it works

How to connect Amazon Aurora to Couchbase — 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.
