Why teams connect Apache Doris and Customer.io

Get the data locked inside Customer.io into Apache Doris as live tables, and send results back where Customer.io can use them, without writing a pipeline.

Whatever Customer.io 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 Objects, Events, Segments, Campaigns from Customer.io into tables in Apache Doris continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Apache Doris can also be written back into fields in Customer.io where the tool can use them.

Common use cases

  • Push CRM segments and lead status into Customer.io so messaging respects sales stage.
  • Land delivery and engagement events (sent, opened, clicked, bounced) from reporting webhooks into a warehouse for attribution analysis.
  • Read aggregates from Doris and sync them into business tools like CRMs or spreadsheets.
  • Consolidate event and transactional data from multiple sources into one real-time OLAP layer.

History that outlives the tool

A continuously synced copy in Apache Doris preserves a queryable record even as data ages out of Customer.io or gets changed inside it.

Analytics on Customer.io's data

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

Cross-tool reporting

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

What you can sync between Apache Doris and Customer.io

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 Doris objects Customer.io objects
Users and Roles Principals used to grant the sync connection scoped access. Objects Non-person entities such as accounts or companies, related to people for account-level messaging.
Databases Logical containers that scope connections and grants. Events Behavioral events sent via the Track API that trigger campaigns.
Tables Columnar tables in one of Doris's table models, used as sync destinations. Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate.
Unique Key Tables Tables supporting primary-key upserts, the natural target for row-level syncs. Campaigns Automated workflows whose membership and metrics can be read via the App API.
Aggregate Key Tables Tables that pre-aggregate on load, used for metric rollups. Broadcasts One-off sends to segments or audiences, triggerable via API.
Partitions Range or list partitions that bound incremental loads. Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks.

How the Apache Doris and Customer.io connectors work

Apache Doris

Integration surface
MySQL wire protocol for SQL access; HTTP APIs (such as Stream Load) for bulk ingestion
Authentication
Database credentials
Change detection
Polling on partition or timestamp columns for reads; ingestion into Doris is push-based via load jobs
Capabilities
read · write
Rate limits
No API quotas; load throughput depends on cluster resources and load-job configuration

Customer.io

Integration surface
REST APIs split by purpose: Track API for data ingestion, App API for campaigns, people lookups, and messages
Authentication
Basic auth with site ID and API key for the Track API; bearer token for the App API
Change detection
Reporting webhooks push message and delivery events; person attribute changes are not streamed and require source-side detection
Capabilities
read · write · webhooks
Rate limits
Subject to per-API rate limits documented by Customer.io
