Why teams connect Apache Kylin and Customer.io

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

Apache Kylin is a read-only source: Stacksync reads its data in real time and delivers it into Customer.io, so Customer.io always reflects the current state of Apache Kylin — without exports, scripts, or schedulers.

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.

Common use cases

  • 01 Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
  • 02 Sync account-level objects and their person relationships for B2B messaging keyed to company attributes.
  • 03 Trigger downstream syncs after segment build jobs complete so consumers only read refreshed data.
  • 04 Read pre-aggregated metrics from Kylin and sync them into CRM fields or planning spreadsheets on a schedule.

Common sync patterns

History that outlives the tool

A continuously synced copy in Apache Kylin 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 Kylin 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 Kylin 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 Kylin objects Customer.io objects How this pairing syncs
Segments Time-ranged build units that partition pre-computed data. Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate. Same entity on both sides — records pair one-to-one and field-level changes reconcile in the writable direction.
Source Tables Hive or other upstream tables that builds read from. Events Behavioral events sent via the Track API that trigger campaigns. Source Tables is specific to Apache Kylin and Events to Customer.io — each maps to any object or custom field on the other side.
Build Jobs Batch jobs that compute or refresh segments, monitored via the REST API. Campaigns Automated workflows whose membership and metrics can be read via the App API. Build Jobs is specific to Apache Kylin and Campaigns to Customer.io — each maps to any object or custom field on the other side.
Projects Top-level workspaces that group models, tables, and jobs. Broadcasts One-off sends to segments or audiences, triggerable via API. Projects is specific to Apache Kylin and Broadcasts to Customer.io — each maps to any object or custom field on the other side.
Models Star-schema definitions over source tables that determine what can be queried. Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. Models is specific to Apache Kylin and Deliveries / Messages to Customer.io — each maps to any object or custom field on the other side.
Cubes / Indexes Pre-computed aggregate structures that answer queries at low latency. Newsletters Recurring email sends with performance metrics available for reporting syncs. Cubes / Indexes is specific to Apache Kylin and Newsletters to Customer.io — each maps to any object or custom field on the other side.

How changes propagate between Apache Kylin and Customer.io

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Apache Kylin Customer.io Interval-based propagation

DetectionStacksync polls Apache Kylin for changes on an incremental schedule, reading only records changed since the previous pass. Data freshness follows segment build and refresh jobs, so integrations poll query results.

DeliveryEach detected change is written to Customer.io through its API, with automatic retries and rate-limit backoff.

Customer.io Apache Kylin Sub-second propagation

DetectionCustomer.io notifies Stacksync of record changes through webhook events. Reporting webhooks push message and delivery events.

DeliveryApache Kylin does not accept inbound record writes, so this direction carries requests rather than records: Apache Kylin's output flows back as field updates on the originating Customer.io records.

Rate-limit considerations

  • Apache Kylin: No fixed API quotas; query capacity depends on the deployment and pre-computed index coverage.
  • Customer.io: Subject to per-API rate limits documented by Customer.io.
