Why teams connect DuckDB and Shopware

Give your engineers Shopware'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 Orders, Order Line Items, Order Deliveries, Order Transactions from Shopware into DuckDB and keeps both sides consistent in real time. Whatever Shopware 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 Shopware 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 Write tracking numbers and delivery state onto `order_delivery` from a 3PL or WMS so storefront order status reflects fulfillment.
  • 04 Consolidate orders and customers from multiple `sales_channel` storefronts into one Postgres database for cross-channel analysis.

Common sync patterns

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.

Controlled write-back

Choose exactly which tables and fields may flow from DuckDB back into Shopware, keeping the store authoritative on what it owns.

Read the store's data with a query

Records from Shopware, whether products, orders, customers, or inventory, live in DuckDB as ordinary tables or collections, joinable with the rest of your data.

What you can sync between DuckDB and Shopware

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 Shopware objects How this pairing syncs
Tables Columnar tables created via SQL; the destination for materialized sync data. Sales Channels Per-storefront configuration (`sales_channel`); used to scope and consolidate orders and customers across multiple storefronts. Tables is specific to DuckDB and Sales Channels to Shopware — each maps to any object or custom field on the other side.
Views SQL views used to shape or filter data for downstream consumers. Media Media assets (`media`) such as product images; referenced by id so file URLs and metadata sync into downstream catalogs. Views is specific to DuckDB and Media to Shopware — each maps to any object or custom field on the other side.
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Products The product catalog (`product`), including parent/child variants, per-currency nested price arrays, and stock; synced two-way with ERP, PIM, or a database. External files (Parquet/CSV/JSON) is specific to DuckDB and Products to Shopware — 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. Categories The navigation and catalogue tree (`category`); mapped to product taxonomy in a warehouse or written from a PIM. Attached databases is specific to DuckDB and Categories to Shopware — 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. Customers Storefront customer accounts (`customer`) with addresses and group; synced two-way with a CRM or support tool. Database files is specific to DuckDB and Customers to Shopware — each maps to any object or custom field on the other side.
Schemas Namespaces within a database used to organize tables in sync outputs. Orders Order headers (`order`) with totals, state, and sales-channel reference; read out to accounting and written back for status updates. Schemas is specific to DuckDB and Orders to Shopware — each maps to any object or custom field on the other side.

How changes propagate between DuckDB and Shopware

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 Shopware 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 Shopware through its API, with automatic retries and rate-limit backoff.

Shopware DuckDB Sub-second propagation

DetectionShopware notifies Stacksync of record changes through webhook events. App-system webhooks on entity events (product.written, order.written, customer.written) deliver the changed record's primaryKey and updated field.

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.
  • Shopware: No general throttle on Admin API entity endpoints; Shopware's RateLimiter guards only specific routes (login, oauth, password reset, guest order/contact) and is configurable on self-hosted stores.
