Delta Sync
Efficient watermark-based change detection for identity synchronization. Process only what changed since the last run — uSNChanged for Active Directory, configurable delta columns for SQL databases.
Key Benefits
Watermark-Based Detection
Changes are tracked via watermarks (uSNChanged for AD, configurable delta columns for SQL), processing only records modified since the last sync run.
Minimal Network Overhead
Only changed attributes are transmitted, dramatically reducing bandwidth usage compared to full-sync approaches.
Confidence-Based Resolution
Each flow rule assigns a confidence score to attribute values. When multiple sources contribute to the same attribute, the highest-confidence value wins.
Change Tracking & Versioning
Every change is versioned and tracked with full history, enabling rollback and detailed audit capabilities.
How It Works
Four stages power the sync pipeline from import to export
Import
Read objects from source connectors using watermark-based delta detection. Only records changed since the last run are imported into the management space.
Join
Anchor-based identity correlation matches imported objects to mesh objects using join rules. New identities are projected into the mesh.
Flow
Attribute mapping and transform rules flow data into mesh objects with confidence scoring. The highest-confidence value wins per attribute.
Export
Projection rules determine what to write to target connectors. Changes are queued in the export queue and written to target systems with audit logging.
Use Cases
Employee Onboarding
When a new employee is created in your HR database, delta sync detects the change and provisions their identity into Active Directory with the appropriate attributes, groups, and OU placement.
Role Changes
Department transfers, promotions, and role changes in the source system are picked up by the next delta sync run. Attribute flow rules update group memberships and attributes in connected systems.
Account Lifecycle
When an account is disabled or deleted in the source system, delta sync detects the change and propagates the status update to all connected target systems on the next run.
