Why teams connect Apache Cassandra and TiDB

Keep Apache Cassandra and TiDB 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 TiDB 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

  • Write attributes computed elsewhere (scores, preferences) back into Cassandra tables serving low-latency reads.
  • Feed Cassandra change streams into search indexes or caches that must track the source of truth.
  • Stream row-level changes to a warehouse or Kafka via CDC for near-real-time analytics
  • Serve mixed transactional and analytical workloads on synced data using TiFlash columnar replicas

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 TiDB, 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 TiDB

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 TiDB objects
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Columns MySQL-compatible types mapped to fields in the paired system.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Indexes Secondary indexes that keep incremental sync queries efficient.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Sequences Server-side ID generation relevant when external systems write rows.
Collections List, set, and map columns handled with type-aware field mapping. Databases MySQL-style schemas addressed by any MySQL-compatible client.
Counters Increment-only counter columns, usually read-only in syncs. Tables Row data stored in TiKV; the primary unit for reads, writes, and CDC.
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Views Logical views for shaping reads before syncing outward.
What ships with Apache Cassandra ⇄ TiDB

Connect Apache Cassandra and TiDB for flexible, real-time data sync.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Apache Cassandra–TiDB connection.

Real-time

Two-way sync

Changes in Apache Cassandra or TiDB instantly reflect in both systems. No stale data, no manual imports.

No-code + pro-code

Workflow automation

Trigger automated workflows whenever Apache Cassandra or TiDB data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single Apache Cassandra or TiDB record.

Observability

Monitoring

Track your Apache Cassandra ⇄ TiDB sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between Apache Cassandra and TiDB.

How the Apache Cassandra and TiDB 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

TiDB

Integration surface
MySQL wire protocol (SQL)
Authentication
Database credentials (MySQL-compatible username/password)
Change detection
Log-based CDC via TiCDC, which captures row changes from TiKV and streams them to downstream sinks; polling also works
Capabilities
read · write · CDC
Rate limits
Throughput scales with cluster size rather than fixed API quotas
How it works

How to connect Apache Cassandra to TiDB — 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.
