Why teams connect Customer.io and StarRocks

Get the data locked inside Customer.io into StarRocks 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 Broadcasts, Deliveries / Messages, Newsletters, People from Customer.io into tables in StarRocks continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in StarRocks can also be written back into fields in Customer.io where the tool can use them.

Common use cases

  • Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
  • Sync account-level objects and their person relationships for B2B messaging keyed to company attributes.
  • Continuously apply upserts from operational databases into Primary Key tables to keep analytics current
  • Serve customer-facing analytics from SaaS data synced into one analytical store

Where Customer.io accepts updates: operational write-back

Segments, scores, or reference values computed in StarRocks sync back onto records in Customer.io, putting analysis where the work happens.

History that outlives the tool

A continuously synced copy in StarRocks 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 StarRocks as queryable tables, current within seconds and ready to join with the rest of the warehouse.

What you can sync between Customer.io and StarRocks

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.

Customer.io objects StarRocks objects
Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate. Columns Columnar storage with types mapped from source systems during sync.
Campaigns Automated workflows whose membership and metrics can be read via the App API. Databases Top-level namespaces addressed exactly as in MySQL clients.
Broadcasts One-off sends to segments or audiences, triggerable via API. Tables Defined with a table model (Primary Key, Unique Key, Aggregate, Duplicate Key) that determines update behavior.
Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. Materialized views Automatically maintained rollups used to accelerate queries on synced data.
Newsletters Recurring email sends with performance metrics available for reporting syncs. Views Logical views for shaping analytical reads.
People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. Partitions Time or range partitions that scope loads and retention.

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

StarRocks

Integration surface
MySQL wire protocol for SQL; HTTP-based Stream Load API for ingestion
Authentication
Database credentials (MySQL-compatible username/password)
Change detection
Query-based polling when reading; StarRocks is most often the destination side of a sync
Capabilities
read · write
Rate limits
Ingestion throughput is bounded by cluster resources rather than API quotas
