Why teams connect DuckDB and Magento

Give your engineers Magento's products, orders, and customers in DuckDB: read them with normal queries, write inventory and prices back through the sync, and skip the storefront API.

E-commerce data sits behind an API built for the storefront, not for your internal systems. Teams that need those records, for order routing, inventory logic, reporting, or back-office tools, end up writing integration code against a rate-limited API and maintaining it through every catalog change and platform upgrade.

Stacksync mirrors Categories, Orders, Customers, Inventory source items (MSI) from Magento into DuckDB and keeps both sides consistent in real time. Whatever Magento holds, whether products, orders, customers, or inventory, those records become rows your code can query, and changes written in DuckDB, such as new prices, stock levels, or fulfillment status, sync back into Magento with its validations respected.

Merchandising and operations keep working in the storefront, engineers keep working in the database, and neither side has to reconcile against a nightly export.

Common use cases

  • 01 Use DuckDB as a transform step: read synced Parquet exports, aggregate with SQL, and write results back to an operational database.
  • 02 Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.
  • 03 Keep MSI inventory source-item quantities aligned between a WMS/ERP and Magento so storefront stock matches the warehouse.
  • 04 Read new Orders to trigger provisioning, accounting, or 3PL fulfillment in an operational database as they are placed.

Common sync patterns

React to store changes

Updates in Magento arrive as row changes in DuckDB, so jobs and triggers can respond the moment an order, price, or stock level changes.

Keep catalog and inventory current

Prices, stock levels, or product details maintained in DuckDB sync back onto Magento, so the storefront shows what your systems treat as true.

Order data where your code can use it

Orders and their status become rows in DuckDB for routing, fulfillment, and reporting, without polling the platform.

What you can sync between DuckDB and Magento

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.

DuckDB objects Magento objects How this pairing syncs
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Carts / quotes Active and guest carts (quotes) with items and totals; read for abandoned-cart analysis (not available on the Cloud Service subset). External files (Parquet/CSV/JSON) is specific to DuckDB and Carts / quotes to Magento — each maps to any object or custom field on the other side.
Attached databases Additional database files or external systems attached into one session for cross-source queries. Products Catalog items keyed by SKU; carry created_at/updated_at for incremental polling and are written two-way from a PIM or ERP into the storefront. Attached databases is specific to DuckDB and Products to Magento — each maps to any object or custom field on the other side.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Configurable / variant products Parent configurable products link to simple product variants by attribute; synced so size/color SKUs and their prices stay aligned with source systems. Database files is specific to DuckDB and Configurable / variant products to Magento — each maps to any object or custom field on the other side.
Schemas Namespaces within a database used to organize tables in sync outputs. Categories Catalog tree and product-to-category assignments; written into Magento to control merchandising and read out for taxonomy reporting. Schemas is specific to DuckDB and Categories to Magento — each maps to any object or custom field on the other side.
Tables Columnar tables created via SQL; the destination for materialized sync data. Orders Sales orders with line items, totals, and status; typically read out of Magento into a warehouse or ERP for fulfillment and revenue reporting. Tables is specific to DuckDB and Orders to Magento — each maps to any object or custom field on the other side.
Views SQL views used to shape or filter data for downstream consumers. Customers Customer accounts and address book; synced two-way with a CRM so order history and contact records stay consistent. Views is specific to DuckDB and Customers to Magento — each maps to any object or custom field on the other side.

How changes propagate between DuckDB and Magento

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.

DuckDB Magento Interval-based propagation

DetectionStacksync polls DuckDB for changes on an incremental schedule, reading only records changed since the previous pass. Polling or full re-reads.

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

Magento DuckDB Sub-second propagation

DetectionMagento notifies Stacksync of record changes through webhook events. Polling with searchCriteria filters on updated_at (catalog, sales, and customer entities carry created_at/updated_at).

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

Rate-limit considerations

  • DuckDB: No API rate limits; throughput is bounded by local compute and I/O.
  • Magento: No fixed request-per-minute cap on PaaS/on-prem; responses page via searchCriteria pageSize/currentPage under a default maximum page size of 300 (Web API Input Limits), with /async/bulk endpoints for large writes.
