Why teams connect Apache Cassandra and Tinybird

Connect Apache Cassandra and Tinybird with one live, two-way sync: operational rows flow into the warehouse, and computed results flow back where systems can read them fast.

Operational databases and analytical warehouses want the same data at different moments. Analysts want Apache Cassandra's rows in Tinybird, current and joinable, without a change-data-capture pipeline to maintain. Engineers want the outputs of warehouse work, such as aggregates, features, and segments, available in Apache Cassandra where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in Apache Cassandra sync into Tinybird in real time, and result tables in Tinybird sync back into Apache Cassandra, with schema and type mapping between the two systems handled for you.

Common use cases

  • Compute aggregates in Tinybird and write the results back to CRM fields for scoring and routing.
  • Stream CRM activity such as deals and tickets into Tinybird Data Sources to power customer-facing dashboards.
  • 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.

Offload heavy reads

Point analytical queries at the synced copy in Tinybird and keep Apache Cassandra focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from Apache Cassandra land in Tinybird as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in Tinybird sync into Apache Cassandra, where whatever reads from that database gets them without querying the warehouse.

What you can sync between Apache Cassandra and Tinybird

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 Tinybird objects
Tables Wide-column tables addressed by partition key, the unit of row-level sync. Workspaces Project boundary that scopes Data Sources, Pipes, and tokens for a sync.
Partitions and Rows Records located by partition and clustering keys during reads and upserts. Tokens Scoped credentials that control read and append rights per resource.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Data Sources ClickHouse-backed tables that receive ingested rows; the write target for syncs into Tinybird.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Pipes Chained SQL nodes that transform Data Sources into query-ready results.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. API Endpoints Published Pipe outputs exposed as parameterized HTTP queries; the main read surface.
Collections List, set, and map columns handled with type-aware field mapping. Materialized Views Pipes materialized into new Data Sources for pre-aggregation at ingest time.

At scale

Event queues

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

Observability

Monitoring

Track your Apache Cassandra ⇄ Tinybird 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 Tinybird.

How the Apache Cassandra and Tinybird 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

Tinybird

Integration surface
REST API (Events API for ingestion, published query endpoints) with a ClickHouse SQL dialect
Authentication
Scoped auth tokens
Change detection
Append-oriented ingestion; reads are pulled by querying published endpoints, no outbound CDC
Capabilities
read · write
Rate limits
Subject to the platform's ingestion and query rate limits; batch appends where possible.
How it works

How to connect Apache Cassandra to Tinybird — three steps, no code
