Why teams connect Active Directory and Apache Druid

Land the users, groups, and access events from Active Directory in Apache Druid continuously for security analytics, and write computed results back — without building or maintaining a pipeline.

Active Directory is the record of who exists and what they can reach; Apache Druid is where the business measures everything else. The two overlap on people and their access — the same users, groups, roles, and events that Active Directory governs are what security, compliance, and analytics teams want to query in Apache Druid. Getting them there usually means a brittle export that runs overnight and hands auditors a snapshot that is already out of date.

Stacksync syncs Organizational units, Organizational contacts, Users, Groups from Active Directory into tables in Apache Druid in real time, and the connection works in both directions: values computed in Apache Druid, such as risk scores or access-review decisions, can be written back to attributes in Active Directory where the identity team acts on them. Schema changes are handled, API limits are managed, and the sync is something you configure rather than a pipeline you keep alive.

Common use cases

  • 01 Query aggregated event metrics from Druid and sync them into CRM account fields for usage-based selling.
  • 02 Feed operational records into Druid via batch ingestion so analysts get interactive slice-and-dice on fresh data.
  • 03 Read Users, Groups, and directoryRole assignments into a warehouse for periodic access reviews and SOC 2 audit evidence.
  • 04 Keep security-group memberships aligned with application entitlement tables so access reflects the right teams as they change.

Common sync patterns

Risk and review results back on the account

Risk scores, anomaly flags, or access-review outcomes computed in Apache Druid write back to attributes on the matching user in Active Directory, where the identity team can act on them.

Directory data in the warehouse, minus the pipeline

Users, groups, and roles from Active Directory arrive in Apache Druid as queryable tables, current within seconds instead of a nightly directory export.

Access and sign-in analytics

Sign-in and access events from Active Directory land in Apache Druid, so security and compliance teams can query who reached what, and when, alongside the rest of the business's data.

What you can sync between Active Directory and Apache Druid

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.

Active Directory objects Apache Druid objects How this pairing syncs
Service principals & applications App registrations and enterprise apps; read-mostly for entitlement and license inventory. Ingestion Supervisors Long-running specs that pull from streams like Kafka; the write path into Druid. Service principals & applications is specific to Active Directory and Ingestion Supervisors to Apache Druid — each maps to any object or custom field on the other side.
Organizational units On-prem AD DS containers (LDAP organizationalUnit) used to scope which users and groups a sync includes. Lookups Key-value mappings joined at query time, refreshable from external systems. Organizational units is specific to Active Directory and Lookups to Apache Druid — each maps to any object or custom field on the other side.
Organizational contacts Directory contact objects (orgContact); synced for shared address-book and CRM person records. Tasks Batch ingestion and compaction jobs monitored during data loads. Organizational contacts is specific to Active Directory and Tasks to Apache Druid — each maps to any object or custom field on the other side.
Users User accounts in Entra ID and on-prem AD DS; synced two-way to create, update attributes, and enable or disable accounts. Datasources The table-like unit of storage and querying, the main target of reads and ingestion. Users is specific to Active Directory and Datasources to Apache Druid — each maps to any object or custom field on the other side.
Groups Security and Microsoft 365 groups; synced two-way including name, type, and owner, with membership tracked separately. Segments Time-partitioned immutable files that hold datasource data; ingestion produces them. Groups is specific to Active Directory and Segments to Apache Druid — each maps to any object or custom field on the other side.
Group memberships Member and owner links between users and groups; membership add/remove changes are surfaced by delta query. Dimensions String and categorical columns used for filtering and grouping in synced queries. Group memberships is specific to Active Directory and Dimensions to Apache Druid — each maps to any object or custom field on the other side.

How changes propagate between Active Directory and Apache Druid

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.

Active Directory Apache Druid Sub-second propagation

DetectionActive Directory notifies Stacksync of record changes through webhook events. Microsoft Graph delta query (change tracking) for Users and Groups, plus change-notification subscriptions (webhooks) for near-real-time triggers.

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

Apache Druid Active Directory 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 Active Directory through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Active Directory: Graph throttles by resource-unit cost per app per tenant in 10-second windows (about 3,500–8,000 units by tenant size); directory delta tokens expire after ~7 days.
  • Apache Druid: No fixed API quotas; query concurrency is bounded by broker and historical node capacity.

How the Active Directory and Apache Druid connectors work

Active Directory

Integration surface
Microsoft Graph REST API (Entra ID / cloud) and LDAP/LDAPS (on-premises AD DS)
Authentication
OAuth 2.0 via the Microsoft identity platform — an app registration with application or delegated permissions (e.g. User.ReadWrite.All, Group.ReadWrite.All) and admin consent; on-prem AD DS uses a bound service account over LDAPS.
Change detection
Microsoft Graph delta query (change tracking) for Users and Groups, plus change-notification subscriptions (webhooks) for near-real-time triggers; on-prem AD DS uses the DirSync control and uSNChanged polling.
Capabilities
read · write · webhooks
Rate limits
Graph throttles by resource-unit cost per app per tenant in 10-second windows (about 3,500–8,000 units by tenant size); directory delta tokens expire after ~7 days.

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
