Why teams connect Apache Druid and Braze

Get the data locked inside Braze into Apache Druid 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 Canvases, Subscription Groups, Content Blocks, Users from Braze into tables in Apache Druid continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Apache Druid can also be written back into fields in Braze where the tool can use them.

Common use cases

  • Sync CRM and billing attributes onto Braze user profiles so lifecycle campaigns target accurate plan and status data.
  • Push product usage events from a database or warehouse into Braze to trigger onboarding and retention journeys.
  • Query aggregated event metrics from Druid and sync them into CRM account fields for usage-based selling.
  • Feed operational records into Druid via batch ingestion so analysts get interactive slice-and-dice on fresh data.

Analytics on Braze's data

Records and events from Braze land in Apache Druid as queryable tables, current within seconds and ready to join with the rest of the warehouse.

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 Apache Druid sync back onto records in Braze, putting analysis where the work happens.

What you can sync between Apache Druid 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 Druid objects Braze objects
Datasources The table-like unit of storage and querying, the main target of reads and ingestion. Custom Events Behavioral events pushed into Braze to trigger campaigns and Canvases.
Segments Time-partitioned immutable files that hold datasource data; ingestion produces them. Purchases Transaction records logged against profiles for revenue-based targeting.
Dimensions String and categorical columns used for filtering and grouping in synced queries. Segments Audience definitions read for membership export and campaign targeting.
Metrics Numeric columns, often pre-aggregated at ingestion via rollup. Campaigns Message sends whose metadata and analytics are read for reporting.
Ingestion Supervisors Long-running specs that pull from streams like Kafka; the write path into Druid. Canvases Multi-step journeys; entry and performance data is read for lifecycle analysis.
Lookups Key-value mappings joined at query time, refreshable from external systems. Subscription Groups Channel-level opt-in states synced with consent records in other systems.

How the Apache Druid and Braze connectors work

Apache Druid

Integration surface
REST API (SQL over HTTP and native JSON queries); JDBC via Avatica
Authentication
Deployment-dependent: basic authentication or an authenticator extension; often fronted by a proxy
Change detection
Not applicable for reads out (polling by time interval); data enters Druid through streaming or batch ingestion rather than row updates
Capabilities
read · write
Rate limits
No fixed API quotas; query concurrency is bounded by broker and historical node capacity

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
