Why teams connect Citus and Shopify

Treat Shopify like part of your database: its records live in Citus 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 Citus, where it can be queried and joined like everything else.

Stacksync mirrors Customers, Abandoned Checkouts, Products, ProductMedias from Shopify into Schemas, Views, Sequences, Distributed tables in Citus with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Shopify 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

  • Write inventory levels from a WMS or ERP into Shopify locations to keep availability accurate.
  • Mirror the product catalog from a PIM or database into Shopify products, variants, and metafields.
  • Consolidate per-tenant rows from distributed tables into per-customer reporting databases.
  • Sync high-volume event or tenant data from a Citus cluster into a warehouse for cross-tenant analytics.

Product events onto CRM records

Signup, usage, or lifecycle changes written to Citus sync onto the matching records in Shopify, 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 Shopify API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in Shopify arrive as row changes in Citus, ready to drive jobs and notifications.

What you can sync between Citus and Shopify

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.

Citus objects Shopify objects
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Orders Purchase transactions; pushed to ERPs for fulfillment and billing, and read into databases for reporting.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Customers Buyer records; matched to CRM contacts for marketing and lifetime-value analysis.
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Abandoned Checkouts Synced with incremental and full sync per the Stacksync docs.
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Products Catalog entries; often mastered in a PIM or ERP and written into Shopify.
Views Curated projections over distributed data, often used as read-only sync sources. ProductMedias Synced with incremental and full sync per the Stacksync docs.
Sequences Key generators that matter when external writes must not collide with application inserts. ProductVariants Synced with incremental and full sync per the Stacksync docs.

How the Citus and Shopify connectors work

Citus

Integration surface
PostgreSQL wire protocol; any standard Postgres driver connects to the coordinator node
Authentication
Database credentials (standard PostgreSQL authentication; managed deployments add cloud IAM options)
Change detection
PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres
Capabilities
read · write · CDC

Shopify

Integration surface
GraphQL Admin API (primary) and REST Admin API (legacy)
Authentication
OAuth via a custom Shopify app: admin creates an app in the Shopify Dev Dashboard, enables required API scopes, sets the Stacksync redirect URL, then supplies shop name + Client ID and Client Secret to Stacksync
Change detection
Webhook topics per resource, with polling on updated_at as a fallback
Capabilities
read · write · webhooks
Rate limits
GraphQL uses a calculated query-cost budget; the REST API uses a leaky-bucket model.
