Why teams connect ClickHouse and Easypost

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

ClickHouse is the analytical store where the business joins, models, and reports on its data; Easypost 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 Views, Materialized views, Distributed tables, Dictionaries in ClickHouse with CarrierAccount, Webhook, Shipment, Address in Easypost 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 Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.
  • 02 Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
  • 03 Batch-create and buy labels for a day's orders, generate a ScanForm, and write each label and tracking code back into the fulfillment system.
  • 04 When an order is ready to ship in an OMS, ERP, or database, create an EasyPost Shipment, buy the lowest qualifying Rate, and write the label URL and tracking code back onto the order.

Common sync patterns

Live analytics on store activity

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

Where Easypost accepts writes: push computed attributes back

Segments, lifetime value, and scores built in ClickHouse write onto the matching records in Easypost, so merchandising and messaging act on warehouse logic.

One product catalog

Where both systems hold product or catalog data, cleaned and enriched attributes stay aligned so the store and the warehouse describe the same items.

What you can sync between ClickHouse and Easypost

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 Easypost objects How this pairing syncs
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Webhook Event subscriptions delivering an Event via HTTP POST on object changes; full CRUD (create, retrieve, list, update, delete) and the mechanism for near-real-time change delivery to Stacksync. Materialized views is specific to ClickHouse and Webhook to Easypost — each maps to any object or custom field on the other side.
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Shipment The central writable object: create with a to/from Address and Parcel, receive Rate options, then buy a label to get postage_label and tracking_code; retrieve and list with cursor pagination. Distributed tables is specific to ClickHouse and Shipment to Easypost — 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. Address Origin and destination locations; create, retrieve, and list, plus address verification (delivery and residential) to normalize and validate addresses before they are saved downstream. Dictionaries is specific to ClickHouse and Address to Easypost — 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. Parcel Package dimensions and weight (or a predefined_package); created standalone or inline on a Shipment and reused across shipments and batches. Tables (MergeTree family) is specific to ClickHouse and Parcel to Easypost — each maps to any object or custom field on the other side.
Databases Namespaces that group tables and scope permissions for sync users. Rate Carrier service and price options EasyPost generates on a Shipment; read-only - you select a rate id and buy it, you do not create or edit rates directly. Databases is specific to ClickHouse and Rate to Easypost — each maps to any object or custom field on the other side.
Views Saved queries used as curated, read-only sync sources. Tracker Tracking for a shipment by tracking_code and carrier; create a Tracker to begin tracking, read status and tracking_details, and receive tracker.updated events via webhook as the parcel moves. Views is specific to ClickHouse and Tracker to Easypost — each maps to any object or custom field on the other side.

How changes propagate between ClickHouse and Easypost

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

Easypost ClickHouse Sub-second propagation

DetectionEasypost notifies Stacksync of record changes through webhook events. Webhooks deliver an Event via HTTP POST on object changes (e.g.

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

Rate-limit considerations

  • Easypost: Fixed 5 requests/second on index (list) endpoints plus a dynamic load-based limiter protecting buy and rate operations; exceeding either returns HTTP 429 Too Many Requests.
