Why teams connect Apache Druid and Attio

Sync Attio 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. Workspaces, Custom objects, People, Companies from Attio land in Apache Druid as live tables, updated within seconds, and columns computed in Apache Druid write back to fields in Attio. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • Keep Attio aligned with a billing system or ERP on customer records and plan status.
  • Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
  • Keep lookup tables in Druid refreshed from a CRM or database so query-time joins use current reference data.
  • Expose product telemetry stored in Druid to business tools without granting direct cluster access.

Cleanup that sticks

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

CRM analytics on live data

Accounts, contacts, and activity from Attio are queryable in Apache Druid moments after they change, so dashboards stop lagging the reality they describe.

Scores and segments back on the record

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

What you can sync between Apache Druid and Attio

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 Attio objects
Metrics Numeric columns, often pre-aggregated at ingestion via rollup. Deals Pipeline records; read out for revenue reporting and written to from automation.
Ingestion Supervisors Long-running specs that pull from streams like Kafka; the write path into Druid. Workspaces Synced with incremental and full sync per the Stacksync docs.
Lookups Key-value mappings joined at query time, refreshable from external systems. Custom objects Workspace-defined objects that behave like standard ones in the API.
Tasks Batch ingestion and compaction jobs monitored during data loads. People Standard person object; synced with marketing tools and warehouse person tables.
Datasources The table-like unit of storage and querying, the main target of reads and ingestion. Companies Standard company object; matched to billing and product accounts in two-way syncs.
Segments Time-partitioned immutable files that hold datasource data; ingestion produces them. Users Synced with incremental and full sync per the Stacksync docs.

How the Apache Druid and Attio connectors work

Apache Druid

Integration surface
REST API (SQL over HTTP and native JSON queries); JDBC via Avatica
Authentication
Deployment-dependent: basic authentication or an authenticator extension; often fronted by a proxy
Change detection
Not applicable for reads out (polling by time interval); data enters Druid through streaming or batch ingestion rather than row updates
Capabilities
read · write
Rate limits
No fixed API quotas; query concurrency is bounded by broker and historical node capacity

Attio

Integration surface
REST API
Authentication
Guided in-app connection ("Attio CRM" connection created in a few clicks, "without any coding required"); the docs do not name the underlying auth mechanism (OAuth vs API key)
Change detection
Webhooks on record and list-entry events, with polling as a fallback
Capabilities
read · write · webhooks
Rate limits
Subject to the platform's published API rate limits.
