Why teams connect Braze and ClickHouse

Get the data locked inside Braze into ClickHouse as live tables, and send results back where Braze can use them, without writing a pipeline.

Whatever Braze is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Purchases, Segments, Campaigns, Canvases from Braze into tables in ClickHouse continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in ClickHouse can also be written back into fields in Braze where the tool can use them.

Common use cases

  • Sync audience membership computed in the warehouse into Braze segments for targeting.
  • Sync CRM and billing attributes onto Braze user profiles so lifecycle campaigns target accurate plan and status data.
  • Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
  • Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.

Cross-tool reporting

Combine Braze's data with data from every other synced system to answer questions no single tool can.

Where Braze accepts updates: operational write-back

Segments, scores, or reference values computed in ClickHouse sync back onto records in Braze, putting analysis where the work happens.

History that outlives the tool

A continuously synced copy in ClickHouse preserves a queryable record even as data ages out of Braze or gets changed inside it.

What you can sync between Braze and ClickHouse

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.

Braze objects ClickHouse objects
Custom Attributes Profile fields written from CRMs, warehouses, and product databases to drive personalization. Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs.
Custom Events Behavioral events pushed into Braze to trigger campaigns and Canvases. Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads.
Purchases Transaction records logged against profiles for revenue-based targeting. Databases Namespaces that group tables and scope permissions for sync users.
Segments Audience definitions read for membership export and campaign targeting. Views Saved queries used as curated, read-only sync sources.
Campaigns Message sends whose metadata and analytics are read for reporting. Materialized views Insert-time transformations that reshape incoming synced rows into aggregates.
Canvases Multi-step journeys; entry and performance data is read for lifecycle analysis. Distributed tables Query-routing tables over cluster shards in self-managed deployments.

How the Braze and ClickHouse connectors work

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

ClickHouse

Integration surface
Native TCP protocol and HTTP interface; standard SQL dialect, with MySQL and PostgreSQL wire compatibility available
Authentication
Database credentials (username/password); ClickHouse Cloud issues per-service credentials over TLS
Change detection
No log-based CDC for consumers; incremental reads use polling on monotonic columns, and ClickHouse is usually the destination rather than the source
