Why teams connect Apache Druid and HubSpot

Sync HubSpot into Apache Druid continuously and push warehouse results back onto CRM records, one two-way connection instead of two pipelines.

The CRM feeds the warehouse and the warehouse should feed the CRM: relationship data flows one way, and computed scores, segments, and customer context flow back. Most teams build the first half as a batch pipeline and never quite get to the second.

Stacksync does both with one connection. Quote, Goal, Owner, Pipeline from HubSpot land in Apache Druid as live tables, updated within seconds, and columns computed in Apache Druid write back to fields in HubSpot. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • 01 Push product signup and usage events into HubSpot contact properties to drive lifecycle marketing segmentation.
  • 02 Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.
  • 03 Feed operational records into Druid via batch ingestion so analysts get interactive slice-and-dice on fresh data.
  • 04 Sync Druid query results into a warehouse to combine real-time aggregates with historical models.

Common sync patterns

Scores and segments back on the record

Lead scores, churn risk, or usage segments computed in Apache Druid appear as fields in HubSpot, where the people working accounts actually see them.

A single customer view

Join HubSpot's relationship data with billing, product, and support data in Apache Druid to build the customer picture the CRM alone cannot hold.

Cleanup that sticks

Deduplication and normalization done in Apache Druid can be written back, so warehouse-side cleanup actually fixes the CRM.

What you can sync between Apache Druid and HubSpot

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 HubSpot objects How this pairing syncs
Dimensions String and categorical columns used for filtering and grouping in synced queries. Quote Synced with incremental and full sync per the Stacksync docs. Dimensions is specific to Apache Druid and Quote to HubSpot — each maps to any object or custom field on the other side.
Metrics Numeric columns, often pre-aggregated at ingestion via rollup. Goal Synced with incremental and full sync per the Stacksync docs. Metrics is specific to Apache Druid and Goal to HubSpot — 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. Owner Synced with incremental and full sync per the Stacksync docs. Ingestion Supervisors is specific to Apache Druid and Owner to HubSpot — each maps to any object or custom field on the other side.
Lookups Key-value mappings joined at query time, refreshable from external systems. Pipeline Synced with incremental and full sync per the Stacksync docs. Lookups is specific to Apache Druid and Pipeline to HubSpot — each maps to any object or custom field on the other side.
Tasks Batch ingestion and compaction jobs monitored during data loads. Stages Synced with incremental and full sync per the Stacksync docs. Tasks is specific to Apache Druid and Stages to HubSpot — each maps to any object or custom field on the other side.
Datasources The table-like unit of storage and querying, the main target of reads and ingestion. Audit Synced with incremental and full sync per the Stacksync docs. Datasources is specific to Apache Druid and Audit to HubSpot — each maps to any object or custom field on the other side.

How changes propagate between Apache Druid and HubSpot

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

HubSpot Apache Druid Sub-second propagation

DetectionHubSpot pushes changes as they happen — webhook events backed by change data capture. Records: incremental near-real-time change tracking.

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.
  • HubSpot: Request limits vary by subscription tier and API type.
