Why teams connect Apache Cassandra and AWS Aurora MySQL

Keep Apache Cassandra and AWS Aurora MySQL 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 AWS Aurora MySQL 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.
  • Stream row changes from Aurora into SaaS tools via binlog CDC instead of scheduled batch exports.
  • Sync a production Aurora cluster with an analytics database while filtering out sensitive columns.

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 Apache Cassandra and AWS Aurora MySQL, 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 Apache Cassandra and AWS Aurora MySQL

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 AWS Aurora MySQL objects
Tables Wide-column tables addressed by partition key, the unit of row-level sync. Databases (schemas) Logical namespaces that scope which tables a sync connection can see.
Partitions and Rows Records located by partition and clustering keys during reads and upserts. Tables The primary sync unit; each table maps one-to-one to a table or object in the paired system.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Rows Inserted, updated, and deleted individually or in bulk during two-way syncs.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Columns MySQL data types are mapped to the paired system's field types during schema setup.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Primary keys and indexes Used to match rows across systems and keep incremental syncs efficient.
Collections List, set, and map columns handled with type-aware field mapping. Views Can serve as read-only sync sources for derived or filtered datasets.

How the Apache Cassandra and AWS Aurora MySQL connectors work

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

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

AWS Aurora MySQL

Integration surface
SQL wire protocol (MySQL-compatible), standard MySQL drivers and JDBC
Authentication
Database credentials, optionally AWS IAM database authentication, over TLS
Change detection
Log-based CDC via the MySQL binary log (binlog), with polling on timestamp columns as a fallback
