Why teams connect CockroachDB and Customer.io

Mirror Customer.io's data into CockroachDB so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Customer.io through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in CockroachDB.

Stacksync mirrors Campaigns, Broadcasts, Deliveries / Messages, Newsletters from Customer.io into Views, Indexes, Sequences, Changefeeds in CockroachDB and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Customer.io, so the tool and the database never disagree.

Common use cases

  • 01 Push CRM segments and lead status into Customer.io so messaging respects sales stage.
  • 02 Land delivery and engagement events (sent, opened, clicked, bounced) from reporting webhooks into a warehouse for attribution analysis.
  • 03 Consolidate data from several SaaS tools into one distributed SQL store that survives zone failures.
  • 04 Write application events from CockroachDB back to CRM fields to give go-to-market teams product context.

Common sync patterns

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Customer.io with a query

Records from Customer.io are ordinary rows in CockroachDB; join them, index them, and use them in application logic without touching the vendor API.

Automate Customer.io from your codebase

Write to the synced tables in CockroachDB and Stacksync propagates the change into Customer.io, replacing custom integration code.

What you can sync between CockroachDB 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.

CockroachDB objects Customer.io objects How this pairing syncs
Databases Logical containers a sync connects to, addressed like PostgreSQL databases. People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. Databases is specific to CockroachDB and People to Customer.io — each maps to any object or custom field on the other side.
Schemas Namespaces within a database used to isolate synced tables from application tables. Objects Non-person entities such as accounts or companies, related to people for account-level messaging. Schemas is specific to CockroachDB and Objects to Customer.io — each maps to any object or custom field on the other side.
Tables The core read/write target; rows sync bi-directionally with SaaS objects or other databases. Events Behavioral events sent via the Track API that trigger campaigns. Tables is specific to CockroachDB and Events to Customer.io — each maps to any object or custom field on the other side.
Views Read-only projections used as curated sync sources. Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate. Views is specific to CockroachDB and Segments to Customer.io — each maps to any object or custom field on the other side.
Indexes Secondary indexes that keep sync lookup queries fast on key columns. Campaigns Automated workflows whose membership and metrics can be read via the App API. Indexes is specific to CockroachDB and Campaigns to Customer.io — each maps to any object or custom field on the other side.
Sequences ID generators that matter when writes originate from an external system. Broadcasts One-off sends to segments or audiences, triggerable via API. Sequences is specific to CockroachDB and Broadcasts to Customer.io — each maps to any object or custom field on the other side.

How changes propagate between CockroachDB 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.

CockroachDB Customer.io Sub-second propagation

DetectionChanges in CockroachDB are captured at the source via change data capture — no polling loop against its API. CDC via changefeeds, which stream row-level changes.

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

Customer.io CockroachDB Sub-second propagation

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

DeliveryEach detected change is applied to CockroachDB as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • CockroachDB: No API rate limits in the SaaS sense; throughput is bounded by cluster capacity.
  • Customer.io: Subject to per-API rate limits documented by Customer.io.
