Why teams connect Apache Druid and Microsoft 365

Get the data locked inside Microsoft 365 into Apache Druid as live tables, and send results back where Microsoft 365 can use them, without writing a pipeline.

Whatever Microsoft 365 is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs OneDrive Files (driveItems), SharePoint Sites & Lists, Teams, Planner & To Do Tasks from Microsoft 365 into tables in Apache Druid continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Apache Druid can also be written back into fields in Microsoft 365 where the tool can use them.

Common use cases

  • Archive mail and file metadata into a warehouse for compliance and activity analytics.
  • Keep CRM contacts and Microsoft 365 contacts aligned in both directions.
  • Feed operational records into Druid via batch ingestion so analysts get interactive slice-and-dice on fresh data.
  • Sync Druid query results into a warehouse to combine real-time aggregates with historical models.

History that outlives the tool

A continuously synced copy in Apache Druid preserves a queryable record even as data ages out of Microsoft 365 or gets changed inside it.

Analytics on Microsoft 365's data

Records and events from Microsoft 365 land in Apache Druid as queryable tables, current within seconds and ready to join with the rest of the warehouse.

Cross-tool reporting

Combine Microsoft 365's data with data from every other synced system to answer questions no single tool can.

What you can sync between Apache Druid and Microsoft 365

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 Microsoft 365 objects
Segments Time-partitioned immutable files that hold datasource data; ingestion produces them. Groups Microsoft 365 and security groups kept aligned with org structure and access rules.
Dimensions String and categorical columns used for filtering and grouping in synced queries. Mail Messages Exchange Online messages read for logging, archiving, or activity capture.
Metrics Numeric columns, often pre-aggregated at ingestion via rollup. Calendar Events Events synced with scheduling tools and CRMs for meeting visibility.
Ingestion Supervisors Long-running specs that pull from streams like Kafka; the write path into Druid. Contacts Personal and org contacts kept consistent with CRM contact records.
Lookups Key-value mappings joined at query time, refreshable from external systems. OneDrive Files (driveItems) File and folder metadata synced for document workflows and audits.
Tasks Batch ingestion and compaction jobs monitored during data loads. SharePoint Sites & Lists List items read and written like lightweight database tables.

How the Apache Druid and Microsoft 365 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

Microsoft 365

Integration surface
REST API (Microsoft Graph)
Authentication
OAuth 2.0 via Microsoft Entra ID, with delegated or application permissions
Change detection
Graph change notifications (webhooks) plus delta queries for incremental sync
Capabilities
read · write · webhooks
