Why teams connect Apache Druid and Easypost

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

Apache Druid 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 Metrics, Ingestion Supervisors, Lookups, Tasks in Apache Druid 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 Druid query results into a warehouse to combine real-time aggregates with historical models.
  • 02 Keep lookup tables in Druid refreshed from a CRM or database so query-time joins use current reference data.
  • 03 Verify and normalize customer Addresses through EasyPost before they are saved to the CRM or OMS to cut failed deliveries and carrier address-correction surcharges.
  • 04 Sync CarrierAccount configuration and negotiated rates so shipping options stay consistent across the storefront, ERP, and 3PL systems.

Common sync patterns

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 Easypost land in Apache Druid 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 Apache Druid write onto the matching records in Easypost, so merchandising and messaging act on warehouse logic.

What you can sync between Apache Druid 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.

Apache Druid objects Easypost objects How this pairing syncs
Datasources The table-like unit of storage and querying, the main target of reads and ingestion. Parcel Package dimensions and weight (or a predefined_package); created standalone or inline on a Shipment and reused across shipments and batches. Datasources is specific to Apache Druid and Parcel to Easypost — each maps to any object or custom field on the other side.
Segments Time-partitioned immutable files that hold datasource data; ingestion produces them. 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. Segments is specific to Apache Druid and Rate to Easypost — each maps to any object or custom field on the other side.
Dimensions String and categorical columns used for filtering and grouping in synced queries. 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. Dimensions is specific to Apache Druid and Tracker to Easypost — each maps to any object or custom field on the other side.
Metrics Numeric columns, often pre-aggregated at ingestion via rollup. Batch Bulk shipment processing; create a batch, add or remove shipments, buy all labels at once, and generate a consolidated label or ScanForm for the day's orders. Metrics is specific to Apache Druid and Batch to Easypost — each maps to any object or custom field on the other side.
Ingestion Supervisors Long-running specs that pull from streams like Kafka; the write path into Druid. CarrierAccount Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts. Ingestion Supervisors is specific to Apache Druid and CarrierAccount to Easypost — each maps to any object or custom field on the other side.
Lookups Key-value mappings joined at query time, refreshable from external systems. 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. Lookups is specific to Apache Druid and Webhook to Easypost — each maps to any object or custom field on the other side.

How changes propagate between Apache Druid 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.

Apache Druid Easypost Interval-based propagation

DetectionStacksync polls Apache Druid for changes on an incremental schedule, reading only records changed since the previous pass. Data enters Druid through streaming or batch ingestion rather than row updates.

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

Easypost Apache Druid 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 Apache Druid as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Apache Druid: No fixed API quotas; query concurrency is bounded by broker and historical node capacity.
  • 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.
