Why teams connect Amazon Aurora and Apache Cassandra

Keep Amazon Aurora and Apache Cassandra 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 Apache Cassandra 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

  • Offload sync reads to Aurora reader endpoints to avoid load on the writer instance.
  • Two-way sync between Aurora application tables and a CRM so product data and account data stay consistent.
  • Consolidate data from multiple keyspaces or clusters into one reporting store.
  • Replicate high-volume event or profile tables from Cassandra into a warehouse for analytics that CQL cannot express.

Shared reference data between services

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

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 Apache Cassandra, so each workload runs on the engine that suits it.

What you can sync between Amazon Aurora and Apache Cassandra

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 Apache Cassandra objects
Read Replicas Reader endpoints that syncs can target to keep load off the writer. Counters Increment-only counter columns, usually read-only in syncs.
Databases Logical databases within a cluster that scope a sync connection. Keyspaces Top-level namespaces with replication settings that scope a sync connection.
Schemas Namespaces (PostgreSQL) or database-level grouping (MySQL) used in table selection. Tables Wide-column tables addressed by partition key, the unit of row-level sync.
Tables Relational tables synced bi-directionally at row level. Partitions and Rows Records located by partition and clustering keys during reads and upserts.
Views Read-only query-backed sources for downstream syncs. Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases.
Materialized Views Precomputed result sets (PostgreSQL-compatible clusters) readable as sources. Secondary Indexes Optional indexes that allow filtered reads outside the partition key.

How the Amazon Aurora and Apache Cassandra 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

Apache Cassandra

Integration surface
CQL over the Cassandra native binary protocol
Authentication
Database credentials (password authenticator); TLS and role-based grants where configured
Change detection
Commit-log based CDC on tables with CDC enabled, or polling using writetime metadata and timestamp columns
Capabilities
read · write · CDC
Rate limits
No API quotas; throughput is governed by cluster capacity and consistency-level choices
How it works

How to connect Amazon Aurora to Apache Cassandra — 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.
