Why teams connect Azure Active Directory and Citus

Close the gap between your application data and your directory: Citus and Azure Active Directory share users, groups, and access in real time, in both directions.

Azure Active Directory is the system of record for who people are and what they can reach: users, the groups they belong to, and the applications assigned to them. Citus holds the operational data those same people show up in, whether an employee or member table that decides who should have an account at all, a customers list, or the rows an application checks before it authorizes an action. The two describe overlapping users and groups, and when a nightly export or a hand-run script is all that connects them, accounts lag joiners and leavers and the application authorizes against a stale picture of who has access.

Stacksync syncs Local tables, Schemas, Views, Sequences in Citus with Applications, Service principals, Directory roles, Devices in Azure Active Directory field by field, in real time, and in both directions. You decide which system owns which fields, with the directory holding credentials and group membership and the database holding the source list of people who should exist at all, and Stacksync keeps every copy consistent, resolving conflicts by rules you set. A person added to a table becomes an account within seconds, a departure disables one just as fast, and the directory's users and groups are always present in your tables as ordinary rows.

Common use cases

  • 01 Use a Citus cluster as the scalable operational store behind a customer-facing app while syncing summaries back to internal tools.
  • 02 Consolidate per-tenant rows from distributed tables into per-customer reporting databases.
  • 03 Mirror Applications and Service principals into a database or CMDB to track app ownership and credential expiry.
  • 04 Reconcile Entra ID Users and assignedLicenses with an ITSM or finance database to audit license allocation and reclaim unused seats.

Common sync patterns

Provision accounts from the source of truth

When a person is added to the employee, member, or customer table in Citus, Stacksync creates the matching user in Azure Active Directory with the right attributes, so access starts from live data instead of a manual ticket.

Deprovision the moment the record changes

When someone is marked inactive or removed in Citus, the matching account in Azure Active Directory is disabled within seconds, closing the window between a departure and a login that still works.

Read users and groups as ordinary tables

Users, groups, and their memberships from Azure Active Directory land in Citus as rows your application and queries can join, so authorization checks and access reporting run against the database instead of the directory API.

What you can sync between Azure Active Directory and Citus

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.

Azure Active Directory objects Citus objects How this pairing syncs
Service principals /servicePrincipals (enterprise apps) plus appRoleAssignments; read for app inventory and access-posture reporting. Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Service principals is specific to Azure Active Directory and Schemas to Citus — each maps to any object or custom field on the other side.
Directory roles /directoryRoles and roleManagement assignments; read for privileged-access reviews, with role-assignment writes where the granted scopes permit. Views Curated projections over distributed data, often used as read-only sync sources. Directory roles is specific to Azure Active Directory and Views to Citus — each maps to any object or custom field on the other side.
Devices /devices registered or joined to the tenant; typically read-only into asset and security databases. Sequences Key generators that matter when external writes must not collide with application inserts. Devices is specific to Azure Active Directory and Sequences to Citus — each maps to any object or custom field on the other side.
Users /users in Microsoft Graph; synced two-way — profile attributes, accountEnabled, and assignedLicenses are read out while provisioning writes (create, update, disable, delete) are pushed back. Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Users is specific to Azure Active Directory and Distributed tables to Citus — each maps to any object or custom field on the other side.
Groups /groups covering security and Microsoft 365 groups; created, updated, and deleted through Graph, and read into warehouses for entitlement reporting. Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Groups is specific to Azure Active Directory and Reference tables to Citus — each maps to any object or custom field on the other side.
Group memberships Member and owner relationships on /groups/{id}/members; added and removed via the $ref endpoint and tracked for changes with delta query on $select=members. Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Group memberships is specific to Azure Active Directory and Local tables to Citus — each maps to any object or custom field on the other side.

How changes propagate between Azure Active Directory and Citus

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.

Azure Active Directory Citus Sub-second propagation

DetectionAzure Active Directory notifies Stacksync of record changes through webhook events. Microsoft Graph delta query (deltaLink tokens returning only changed users and groups, with @removed deletions) paired with change-notification.

DeliveryEach detected change is applied to Citus as a row-level write, with types converted between the two schemas.

Citus Azure Active Directory Sub-second propagation

DetectionChanges in Citus are captured at the source via change data capture — no polling loop against its API. PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres.

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

Rate-limit considerations

  • Azure Active Directory: Resource-unit throttling: roughly 8,000 ResourceUnits per 10 seconds per app for reads on tenants over 500 users, writes near 3,000 requests per 2.5 minutes; 429 responses include a Retry-After header.
