Why teams connect Apache Cassandra and Apache Pinot

Connect Apache Cassandra and Apache Pinot 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 Apache Pinot, 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 Apache Pinot in real time, and result tables in Apache Pinot sync back into Apache Cassandra, with schema and type mapping between the two systems handled for you.

Common use cases

  • Query per-account usage metrics from Pinot and sync them into CRM fields so sales sees product activity.
  • Push reference and dimension data into Pinot via batch segment loads to enrich event queries.
  • 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.

Fresh analytics without loading windows

Because changes stream continuously, analysts query current data instead of waiting for last night's load.

Offload heavy reads

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

Operational data in the warehouse, minus the pipeline

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

What you can sync between Apache Cassandra and Apache Pinot

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 Apache Pinot objects
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Real-time Tables Tables fed continuously from streams like Kafka, including upsert-enabled tables.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Offline Tables Batch-loaded tables merged with real-time data at query time.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Indexes Inverted, range, and star-tree indexes that determine which sync queries run at low latency.
Collections List, set, and map columns handled with type-aware field mapping. Tenants Logical groupings that isolate workloads on shared clusters.
Counters Increment-only counter columns, usually read-only in syncs. Tables The queryable unit, defined as offline, real-time, or hybrid; the main read target.
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Schemas Column definitions (dimensions, metrics, time columns) mapped during integration setup.

How the Apache Cassandra and Apache Pinot 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

Apache Pinot

Integration surface
REST API (SQL queries via the broker; administration via the controller); JDBC client available
Authentication
Deployment-dependent: HTTP basic authentication or token-based auth where enabled
Change detection
Not applicable for reads out (polling by time column); data enters Pinot via streaming ingestion or segment upload, not row-level writes
Capabilities
read · write
Rate limits
No fixed API quotas; query throughput depends on broker and server sizing
How it works
