Why teams connect ClickHouse and Nuorder

Make ClickHouse the analytics and enrichment layer behind Nuorder: orders, products, and customers stay current in both directions.

ClickHouse is the analytical store where the business joins, models, and reports on its data; Nuorder runs the storefront, catalog, and transactions that generate most of it. The overlap is every record that has to be counted and enriched on one side and acted on the other — and when the bridge is a nightly export, the warehouse reports on yesterday while the store operates without the segments and metrics the warehouse just computed.

Stacksync syncs Databases, Views, Materialized views, Distributed tables in ClickHouse with Orders, Companies, Line Items, Inventory (ATS) in Nuorder field by field, in real time, and in both directions. Transactional records land in the warehouse as they change, computed attributes and cleaned catalog data flow back to the store, and you decide which system owns which fields so Stacksync resolves conflicts by rules you set.

Common use cases

  • 01 Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
  • 02 Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.
  • 03 Two-way sync Companies (retail accounts) between NuORDER and a CRM so buyers created in either system stay aligned on customer master data.
  • 04 Poll the modified-orders date-range endpoint on a schedule to land new and updated Orders in a Postgres warehouse for sell-in and buyer analytics.

Common sync patterns

Inventory and order status reconciled

Stock levels and order or fulfillment status move between ClickHouse and Nuorder so counts and states agree across reporting and operations.

One customer master

Where both systems keep customer records, corrections in either propagate to the other so analytics and the storefront share one identity.

Live analytics on store activity

Orders, products, and customer records from Nuorder land in ClickHouse as they change, so dashboards and models read current data instead of last night's export.

What you can sync between ClickHouse and Nuorder

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.

ClickHouse objects Nuorder objects How this pairing syncs
Views Saved queries used as curated, read-only sync sources. Pricing / Price Lists Wholesale and retail price data attached to products through the product data feeds; read out for margin reporting or written in during catalog loads. Views is specific to ClickHouse and Pricing / Price Lists to Nuorder — each maps to any object or custom field on the other side.
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Payments Payment status and detail returned alongside Orders (the modified-orders date-range query returns the order plus its payment information); read-oriented in most syncs. Materialized views is specific to ClickHouse and Payments to Nuorder — each maps to any object or custom field on the other side.
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Products Fluent-schema catalog records (style, SKU, images, custom fields); brands push them in via /api/product/new (POST) and update via /api/product/{id} (PUT), typically mastered in a PIM or ERP. Distributed tables is specific to ClickHouse and Products to Nuorder — each maps to any object or custom field on the other side.
Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Orders Wholesale sales orders with nested line items and payment info; read via /api/orders/{status}/detail, created via /api/order/new (PUT), and advanced via /api/order/{id}/process and /cancel. Dictionaries is specific to ClickHouse and Orders to Nuorder — each maps to any object or custom field on the other side.
Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Companies Retailer and customer accounts (buyers, doors); enumerated via /api/companies/codes/list and created through the customer-creation API, commonly synced with a CRM or ERP. Tables (MergeTree family) is specific to ClickHouse and Companies to Nuorder — each maps to any object or custom field on the other side.
Databases Namespaces that group tables and scope permissions for sync users. Line Items SKU, quantity, and price rows nested inside each Order; the unit ERPs and fulfillment systems consume when an order is written out. Databases is specific to ClickHouse and Line Items to Nuorder — each maps to any object or custom field on the other side.

How changes propagate between ClickHouse and Nuorder

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.

ClickHouse Nuorder Interval-based propagation

DetectionStacksync polls ClickHouse for changes on an incremental schedule, reading only records changed since the previous pass. No log-based CDC for consumers.

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

Nuorder ClickHouse Interval-based propagation

DetectionStacksync polls Nuorder for changes on an incremental schedule, reading only records changed since the previous pass. Polling on modified date: a date-range order endpoint returns the IDs of orders changed within a UTC start/end window.

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

Rate-limit considerations

  • Nuorder: Results are cursor-paginated via lastId/lastValue exposed in a 'next' response header (null on the last page); published request-rate limits are not documented and are governed per integration.

How the ClickHouse and Nuorder connectors work

ClickHouse

Integration surface
Native TCP protocol and HTTP interface; standard SQL dialect, with MySQL and PostgreSQL wire compatibility available
Authentication
Database credentials (username/password); ClickHouse Cloud issues per-service credentials over TLS
Change detection
No log-based CDC for consumers; incremental reads use polling on monotonic columns, and ClickHouse is usually the destination rather than the source
Capabilities

Nuorder

Integration surface
REST API (JSON), with optional SFTP flat-file data feeds
Authentication
OAuth 1.0 — consumer key/secret plus an access token/secret issued per approved application in the NuORDER Portal (Admin > Settings > API Management > Approved Applications)
Change detection
Polling on modified date: a date-range order endpoint returns the IDs of orders changed within a UTC start/end window; products and customers are pulled by last-modified date. No native webhooks.
