Why teams connect Amazon RDS and Kustomer

Treat Kustomer like part of your database: its records live in Amazon RDS as real tables, and writes in either place sync to the other in seconds.

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in Amazon RDS, where it can be queried and joined like everything else.

Stacksync mirrors Tags, Notes, Customers, Conversations from Kustomer into Schemas, Tables, Views, Columns in Amazon RDS with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Kustomer with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

  • 01 Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
  • 02 Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
  • 03 Sync master data (customers, products, pricing) from an ERP into the RDS databases that power customer-facing apps
  • 04 Use a read replica as the sync source to keep change capture load off the primary instance

Common sync patterns

Query the CRM like a database

Accounts, contacts, and custom objects from Kustomer become tables in Amazon RDS you can join with application data directly.

Product events onto CRM records

Signup, usage, or lifecycle changes written to Amazon RDS sync onto the matching records in Kustomer, giving go-to-market teams live product context.

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the Kustomer API, limits, and retries.

What you can sync between Amazon RDS and Kustomer

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 RDS objects Kustomer objects How this pairing syncs
Tables The core sync target; rows map to records in connected SaaS systems. Notes Internal annotations carry context alongside synced conversations. Tables is specific to Amazon RDS and Notes to Kustomer — each maps to any object or custom field on the other side.
Views Read-side projections exposed to outbound syncs. Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. Views is specific to Amazon RDS and Customers to Kustomer — each maps to any object or custom field on the other side.
Columns Field-level mapping targets, typed per the underlying engine. Conversations Support threads across channels sync outward for analytics and CRM context. Columns is specific to Amazon RDS and Conversations to Kustomer — each maps to any object or custom field on the other side.
Primary and Unique Keys Match keys for idempotent upserts. Messages Individual messages within conversations support full-thread replication. Primary and Unique Keys is specific to Amazon RDS and Messages to Kustomer — each maps to any object or custom field on the other side.
Read Replicas Low-impact read endpoints often used as the source side of a sync. Companies Organization records group customers and map to CRM accounts. Read Replicas is specific to Amazon RDS and Companies to Kustomer — each maps to any object or custom field on the other side.
Stored Procedures Engine-specific logic that can react to synced rows. Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. Stored Procedures is specific to Amazon RDS and Custom Objects (Klasses) to Kustomer — each maps to any object or custom field on the other side.

How changes propagate between Amazon RDS and Kustomer

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 RDS Kustomer Sub-second propagation

DetectionChanges in Amazon RDS are captured at the source via change data capture — no polling loop against its API. Engine-native log-based CDC: MySQL/MariaDB binlog, PostgreSQL logical replication, SQL Server CDC.

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

Kustomer Amazon RDS Sub-second propagation

DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.

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

Rate-limit considerations

  • Amazon RDS: No API rate limits; throughput depends on instance class, storage IOPS, and connection limits.
  • Kustomer: Subject to the platform's API rate limits.
