Why teams connect Amazon Aurora and Customer.io

Mirror Customer.io's data into Amazon Aurora 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 Amazon Aurora.

Stacksync mirrors Deliveries / Messages, Newsletters, People, Objects from Customer.io into Databases, Schemas, Tables, Views in Amazon Aurora 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 Two-way sync between Aurora application tables and a CRM so product data and account data stay consistent.
  • 04 Stream row-level changes from Aurora into a warehouse for near-real-time analytics without batch exports.

Common sync patterns

Read Customer.io with a query

Records from Customer.io are ordinary rows in Amazon Aurora; 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 Amazon Aurora and Stacksync propagates the change into Customer.io, replacing custom integration code.

React to changes as they happen

Updates in Customer.io arrive as row changes in Amazon Aurora, so triggers, jobs, and services can respond in near real time.

What you can sync between Amazon Aurora 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.

Amazon Aurora objects Customer.io objects How this pairing syncs
Primary and Foreign Keys Constraints used to identify records and preserve relational integrity in syncs. Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate. Primary and Foreign Keys is specific to Amazon Aurora and Segments to Customer.io — each maps to any object or custom field on the other side.
Read Replicas Reader endpoints that syncs can target to keep load off the writer. Campaigns Automated workflows whose membership and metrics can be read via the App API. Read Replicas is specific to Amazon Aurora and Campaigns to Customer.io — each maps to any object or custom field on the other side.
Databases Logical databases within a cluster that scope a sync connection. Broadcasts One-off sends to segments or audiences, triggerable via API. Databases is specific to Amazon Aurora and Broadcasts to Customer.io — each maps to any object or custom field on the other side.
Schemas Namespaces (PostgreSQL) or database-level grouping (MySQL) used in table selection. Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. Schemas is specific to Amazon Aurora and Deliveries / Messages to Customer.io — each maps to any object or custom field on the other side.
Tables Relational tables synced bi-directionally at row level. Newsletters Recurring email sends with performance metrics available for reporting syncs. Tables is specific to Amazon Aurora and Newsletters to Customer.io — each maps to any object or custom field on the other side.
Views Read-only query-backed sources for downstream syncs. People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. Views is specific to Amazon Aurora and People to Customer.io — each maps to any object or custom field on the other side.

How changes propagate between Amazon Aurora 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.

Amazon Aurora Customer.io Sub-second propagation

DetectionChanges in Amazon Aurora are captured at the source via change data capture — no polling loop against its API. Log-based CDC: binlog on MySQL-compatible clusters, logical replication/decoding on PostgreSQL-compatible clusters.

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

Customer.io Amazon Aurora 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 Amazon Aurora as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Amazon Aurora: No API rate limits for wire-protocol access; throughput is bounded by instance class and connection limits.
  • Customer.io: Subject to per-API rate limits documented by Customer.io.
