Why teams connect Apache Cassandra and SingleStore

Keep Apache Cassandra and SingleStore 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 SingleStore 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.
  • Feed synced operational data into applications that need low-latency responses over fresh data.
  • Mirror CRM and SaaS objects into SingleStore tables to serve low-latency operational dashboards.

Cross-engine sync

Keep the same dataset live in both Apache Cassandra and SingleStore, 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 SingleStore

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 SingleStore objects
Partitions and Rows Records located by partition and clustering keys during reads and upserts. Indexes and Shard Keys Determine data distribution and lookup speed for sync match keys.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Databases The connection target containing the tables a sync addresses.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Tables (rowstore and columnstore) Primary read/write target; storage type affects whether a table suits point lookups or scans.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Views Read-only projections used as curated sync sources.
Collections List, set, and map columns handled with type-aware field mapping. Reference Tables Small tables replicated to every node, often used for dimension data in syncs.
Counters Increment-only counter columns, usually read-only in syncs. Pipelines Native ingestion jobs from Kafka or object storage that coexist with external syncs.

How the Apache Cassandra and SingleStore 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

SingleStore

Integration surface
SQL over the MySQL wire protocol; an HTTP Data API is also available for SQL over REST
Authentication
Database credentials
Change detection
Polling on timestamp or watermark columns; the platform also provides change-observation features in recent versions
Capabilities

Rate limits
No API rate limits; throughput is bounded by workspace or cluster size
How it works

How to connect Apache Cassandra to SingleStore — 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.
