Why teams connect Apache Kylin and Resend

Get the data locked inside Resend into Apache Kylin as live tables, and send results back where Resend 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 Resend, so Resend always reflects the current state of Apache Kylin — without exports, scripts, or schedulers.

Whatever Resend 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

  • Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
  • Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • Sync Kylin aggregates into a cloud warehouse to combine them with data Kylin does not cover.
  • Trigger downstream syncs after segment build jobs complete so consumers only read refreshed data.

Analytics on Resend's data

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

Cross-tool reporting

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

Where Resend accepts updates: operational write-back

Segments, scores, or reference values computed in Apache Kylin sync back onto records in Resend, putting analysis where the work happens.

What you can sync between Apache Kylin and Resend

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 Resend objects
Projects Top-level workspaces that group models, tables, and jobs. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases.
Models Star-schema definitions over source tables that determine what can be queried. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments.
Cubes / Indexes Pre-computed aggregate structures that answer queries at low latency. Broadcasts One-to-many campaign sends addressed to an audience.
Source Tables Hive or other upstream tables that builds read from. Domains Verified sending domains with DNS and DKIM status.
Segments Time-ranged build units that partition pre-computed data. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems.
Build Jobs Batch jobs that compute or refresh segments, monitored via the REST API. API keys Scoped credentials managed per environment for send and read access.

Apache Kylin

Integration surface
SQL over JDBC/ODBC plus a REST API for queries and administration
Authentication
Username/password (HTTP basic authentication on the REST API)
Change detection
Not applicable for row-level capture; data freshness follows segment build and refresh jobs, so integrations poll query results
Capabilities
read
Rate limits
No fixed API quotas; query capacity depends on the deployment and pre-computed index coverage

Resend

Integration surface
REST API
Authentication
API key (Bearer token)
Change detection
Webhooks for email lifecycle events; polling for contact and audience state
