Why teams connect ClickHouse and Linnworks

Put Linnworks's records in ClickHouse as live tables for reporting and analysis, without extract jobs, and write results back where Linnworks can use them.

ERP data is some of the most asked-for data in the warehouse and some of the hardest to get: the record types are many, the APIs are strict, and extract jobs are brittle. Whether Linnworks carries financials, operations, workforce data, or all three, the analysis belongs in ClickHouse next to everything else the company measures.

Stacksync syncs Stock Items, Stock Levels, Locations, Purchase Orders from Linnworks into tables in ClickHouse continuously, managing API limits and schema drift along the way. The connection is bi-directional, so values computed in ClickHouse can be written back to fields in Linnworks where that is useful.

Common use cases

  • Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.
  • Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
  • Push customer and order data to a CRM or marketing platform for post-purchase campaigns
  • Sync orders from Linnworks into an ERP or accounting system as they are processed, without CSV exports

ClickHouse objects Linnworks objects
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Processed Orders Completed orders feed accounting and warehouse-based margin reporting.
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Stock Items SKU records keep product data aligned with ERPs and PIMs.
Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Stock Levels Per-location quantities sync outward so channels and planning tools reflect current availability.
Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Locations Warehouse and fulfillment location records scope stock data during mapping.
Databases Namespaces that group tables and scope permissions for sync users. Purchase Orders Replenishment POs sync with suppliers and accounting systems.
Views Saved queries used as curated, read-only sync sources. Suppliers Vendor records keep procurement data consistent across tools.
