Why teams connect Citus and Microsoft 365

Mirror Microsoft 365's data into Citus so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Microsoft 365 through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Citus.

Stacksync mirrors Planner & To Do Tasks, Users, Groups, Mail Messages from Microsoft 365 into Reference tables, Local tables, Schemas, Views in Citus and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Microsoft 365, so the tool and the database never disagree.

Common use cases

  • Mirror calendar events into scheduling or CRM tools so meetings appear on customer timelines.
  • Sync SharePoint lists with operational databases so business users edit in SharePoint while systems read SQL.
  • Use a Citus cluster as the scalable operational store behind a customer-facing app while syncing summaries back to internal tools.
  • Consolidate per-tenant rows from distributed tables into per-customer reporting databases.

Automate Microsoft 365 from your codebase

Write to the synced tables in Citus and Stacksync propagates the change into Microsoft 365, replacing custom integration code.

React to changes as they happen

Updates in Microsoft 365 arrive as row changes in Citus, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

What you can sync between Citus 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.

Citus objects Microsoft 365 objects
Views Curated projections over distributed data, often used as read-only sync sources. Planner & To Do Tasks Task items synced with project and work-management tools.
Sequences Key generators that matter when external writes must not collide with application inserts. Users Entra ID user accounts synced with HR and identity systems.
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Groups Microsoft 365 and security groups kept aligned with org structure and access rules.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Mail Messages Exchange Online messages read for logging, archiving, or activity capture.
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Calendar Events Events synced with scheduling tools and CRMs for meeting visibility.
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Contacts Personal and org contacts kept consistent with CRM contact records.
