Why teams connect Apache Cassandra and Braze

Mirror Braze's data into Apache Cassandra so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Braze through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Apache Cassandra.

Stacksync mirrors Custom Attributes, Custom Events, Purchases, Segments from Braze into Keyspaces, Tables, Partitions and Rows, Materialized Views in Apache Cassandra and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Braze, so the tool and the database never disagree.

Common use cases

  • Keep subscription and consent states consistent between Braze subscription groups and the CRM or CDP of record.
  • Export campaign and Canvas engagement data into a warehouse for cross-channel reporting.
  • Sync customer profile data between Cassandra and a CRM so operational apps and sales tools agree.
  • Write attributes computed elsewhere (scores, preferences) back into Cassandra tables serving low-latency reads.

Read Braze with a query

Records from Braze are ordinary rows in Apache Cassandra; join them, index them, and use them in application logic without touching the vendor API.

Automate Braze from your codebase

Write to the synced tables in Apache Cassandra and Stacksync propagates the change into Braze, replacing custom integration code.

React to changes as they happen

Updates in Braze arrive as row changes in Apache Cassandra, so triggers, jobs, and services can respond in near real time.

What you can sync between Apache Cassandra and Braze

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 Braze objects
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Campaigns Message sends whose metadata and analytics are read for reporting.
Tables Wide-column tables addressed by partition key, the unit of row-level sync. Canvases Multi-step journeys; entry and performance data is read for lifecycle analysis.
Partitions and Rows Records located by partition and clustering keys during reads and upserts. Subscription Groups Channel-level opt-in states synced with consent records in other systems.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Content Blocks Reusable message content referenced across campaigns.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Users The central profile object, identified by external ID, Braze ID, or user aliases; the main sync target.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Custom Attributes Profile fields written from CRMs, warehouses, and product databases to drive personalization.

Trigger automated workflows whenever Apache Cassandra or Braze 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 Braze record.

Observability

Monitoring

Track your Apache Cassandra ⇄ Braze 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 Braze.

How the Apache Cassandra and Braze 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

Braze

Integration surface
REST API
Authentication
REST API keys scoped to specific endpoints, issued per workspace
Change detection
Braze Currents streams engagement events outward; profile reads otherwise rely on export endpoints and polling
Capabilities
read · write
Rate limits
Endpoints have per-endpoint rate limits documented by Braze; batch endpoints accept multiple users per request
