Why teams connect Apache Cassandra and CockroachDB

Keep Apache Cassandra and CockroachDB 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 CockroachDB 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

  • Feed Cassandra change streams into search indexes or caches that must track the source of truth.
  • Consolidate data from multiple keyspaces or clusters into one reporting store.
  • Use changefeeds to propagate row changes from a multi-region cluster into a warehouse or search index.
  • Keep reference data consistent between CockroachDB and regional application databases.

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

What you can sync between Apache Cassandra and CockroachDB

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 CockroachDB objects
Tables Wide-column tables addressed by partition key, the unit of row-level sync. Schemas Namespaces within a database used to isolate synced tables from application tables.
Partitions and Rows Records located by partition and clustering keys during reads and upserts. Tables The core read/write target; rows sync bi-directionally with SaaS objects or other databases.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Views Read-only projections used as curated sync sources.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Indexes Secondary indexes that keep sync lookup queries fast on key columns.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Sequences ID generators that matter when writes originate from an external system.
Collections List, set, and map columns handled with type-aware field mapping. Changefeeds Built-in CDC streams that emit row-level changes to external sinks.

How the Apache Cassandra and CockroachDB 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
read · write · CDC
Rate limits
No API quotas; throughput is governed by cluster capacity and consistency-level choices

CockroachDB

Integration surface
SQL wire protocol (PostgreSQL-compatible)
Authentication
Database credentials with TLS; client certificates or SCRAM password auth
Change detection
CDC via changefeeds, which stream row-level changes; polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits in the SaaS sense; throughput is bounded by cluster capacity
How it works

How to connect Apache Cassandra to CockroachDB — 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.
