Why teams connect Google Cloud Spanner and Shopify

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

Stacksync mirrors ProductMedias, ProductVariants, Orders, Customers from Shopify into Secondary indexes, Change streams, Views, Databases in Google Cloud Spanner 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

  • 01 Sync orders, customers, and inventory into Postgres for operational reporting across stores.
  • 02 Keep customer records aligned between Shopify and a CRM for segmentation and lifetime-value analysis.
  • 03 Consolidate data from a globally distributed Spanner deployment into regional business systems.
  • 04 Push billing or entitlement changes from finance tools into Spanner tables the application reads at runtime.

Common sync patterns

Trigger workflows from CRM changes

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

Query the CRM like a database

Accounts, contacts, and custom objects from Shopify become tables in Google Cloud Spanner you can join with application data directly.

Product events onto CRM records

Signup, usage, or lifecycle changes written to Google Cloud Spanner sync onto the matching records in Shopify, giving go-to-market teams live product context.

What you can sync between Google Cloud Spanner 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.

Google Cloud Spanner objects Shopify objects How this pairing syncs
Rows The unit of read and write in each sync cycle, keyed by primary key. ProductMedias Synced with incremental and full sync per the Stacksync docs. Rows is specific to Google Cloud Spanner and ProductMedias to Shopify — each maps to any object or custom field on the other side.
Interleaved tables Child rows physically co-located with parents; synced as related records. ProductVariants Synced with incremental and full sync per the Stacksync docs. Interleaved tables is specific to Google Cloud Spanner and ProductVariants to Shopify — each maps to any object or custom field on the other side.
Secondary indexes Used to make incremental read queries efficient on non-key columns. Orders Purchase transactions; pushed to ERPs for fulfillment and billing, and read into databases for reporting. Secondary indexes is specific to Google Cloud Spanner and Orders to Shopify — each maps to any object or custom field on the other side.
Change streams Capture inserts, updates, and deletes for log-style change data capture. Customers Buyer records; matched to CRM contacts for marketing and lifetime-value analysis. Change streams is specific to Google Cloud Spanner and Customers to Shopify — each maps to any object or custom field on the other side.
Views Read-only projections useful for shaping data before it leaves Spanner. Abandoned Checkouts Synced with incremental and full sync per the Stacksync docs. Views is specific to Google Cloud Spanner and Abandoned Checkouts to Shopify — each maps to any object or custom field on the other side.
Databases Top-level containers that scope schema and sync configuration. Products Catalog entries; often mastered in a PIM or ERP and written into Shopify. Databases is specific to Google Cloud Spanner and Products to Shopify — each maps to any object or custom field on the other side.

How changes propagate between Google Cloud Spanner and Shopify

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.

Google Cloud Spanner Shopify Sub-second propagation

DetectionChanges in Google Cloud Spanner are captured at the source via change data capture — no polling loop against its API. Change streams (log-style CDC), or timestamp-based polling queries.

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

Shopify Google Cloud Spanner Sub-second propagation

DetectionShopify notifies Stacksync of record changes through webhook events. Webhook topics per resource, with polling on updated_at as a fallback.

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

Rate-limit considerations

  • Google Cloud Spanner: Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.
  • Shopify: GraphQL uses a calculated query-cost budget; the REST API uses a leaky-bucket model.
