Why teams connect MongoDB and Ukg Ready

Put your workforce data where your apps can reach it: MongoDB and Ukg Ready share the same people, positions, and org structure in real time.

Ukg Ready is the system of record for the people side of the business — employees, candidates, roles, and the org structure around them. MongoDB is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Compensation, Timesheet Entries, Accruals / Time Off, Payroll (Earnings / Deductions / Employee Payroll Runs) in Ukg Ready need to exist as queryable Collections, Documents, Embedded documents and arrays, Indexes in MongoDB before an app can act on them. When that bridge is a nightly export or a hand-run CSV, every downstream system spends the day working from a roster that has already moved on.

Stacksync syncs Collections, Documents, Embedded documents and arrays, Indexes in MongoDB with Compensation, Timesheet Entries, Accruals / Time Off, Payroll (Earnings / Deductions / Employee Payroll Runs) in Ukg Ready field by field, in real time. You decide which system owns which fields — Ukg Ready typically owns identity and org attributes, while operational or computed values can flow back the other way — and Stacksync keeps every copy consistent, matching records on a stable key and resolving conflicts by rules you set.

The result is one live picture of the workforce on both sides: HR keeps its source of truth, and the database keeps a current mirror that internal apps, reports, and access controls can trust without a batch window in between.

Common use cases

  • 01 Sync MongoDB collections with a CRM so customer documents written by the application appear as CRM records, and CRM edits flow back as document updates.
  • 02 Replicate operational MongoDB data into a relational database, flattening nested documents into normalized tables for SQL reporting.
  • 03 Two-way sync Employees and Employment/Position records with an operational Postgres database so internal apps and IT provisioning read job title, department, and status in SQL while HR edits in UKG Ready.
  • 04 Import computed Earnings and deductions into UKG Ready payroll runs from a warehouse or external time-tracking system ahead of each pay period.

Common sync patterns

Mirror people records into the database

Records maintained in Ukg Ready land as queryable Collections, Documents, Embedded documents and arrays, Indexes in MongoDB, so internal apps and dashboards read live data instead of a periodic export.

One directory of record

When a person record is added, changed, or deactivated in either system, the matching row in the other stays current, ending dual maintenance.

Reporting and analytics on current data

Compensation, Timesheet Entries, Accruals / Time Off, Payroll (Earnings / Deductions / Employee Payroll Runs) replicate into MongoDB where they join operational tables, so headcount, roles, and status reports run on the live state without manual pulls.

What you can sync between MongoDB and Ukg Ready

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.

MongoDB objects Ukg Ready objects How this pairing syncs
Change streams The oplog-backed event feed that powers real-time change capture. Cost Centers / Groups Departments, locations, and hierarchy used as org structure; read to align headcount and budget models across systems. Change streams is specific to MongoDB and Cost Centers / Groups to Ukg Ready — each maps to any object or custom field on the other side.
GridFS files Chunked file storage whose metadata can be referenced by synced documents. Reports (Report-as-a-Service) Scheduled IBM Cognos extracts used for bulk historical pulls that the per-employee REST endpoints are not built for. GridFS files is specific to MongoDB and Reports (Report-as-a-Service) to Ukg Ready — each maps to any object or custom field on the other side.
Databases Logical groupings of collections that scope a sync connection. Employees Core person records (demographics, contact info, status, work location); synced two-way and mapped to HRIS or person tables in a database. Databases is specific to MongoDB and Employees to Ukg Ready — each maps to any object or custom field on the other side.
Collections The table-like sync unit; each collection maps to a table or object in the paired system. Employment / Positions Job title, department, employment type, hire and termination dates; read for org modeling and written when roles change. Collections is specific to MongoDB and Employment / Positions to Ukg Ready — each maps to any object or custom field on the other side.
Documents BSON records created, updated, and deleted during syncs, keyed by _id. Compensation Salary or hourly rate, pay frequency, and FLSA status; often mastered elsewhere and written onto the employee record, or read into finance. Documents is specific to MongoDB and Compensation to Ukg Ready — each maps to any object or custom field on the other side.
Embedded documents and arrays Nested structures that syncs flatten or map to related records in relational targets. Timesheet Entries Time-and-attendance punches, hours worked, and breaks; written from external time systems and read into warehouses for labor-cost reporting. Embedded documents and arrays is specific to MongoDB and Timesheet Entries to Ukg Ready — each maps to any object or custom field on the other side.

How changes propagate between MongoDB and Ukg Ready

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.

MongoDB Ukg Ready Sub-second propagation

DetectionChanges in MongoDB are captured at the source via change data capture — no polling loop against its API. MongoDB oplog and change streams (requires the database to run as a replica set — even single-node).

DeliveryEach detected change is written to Ukg Ready through its API, with automatic retries and rate-limit backoff.

Ukg Ready MongoDB Sub-second propagation

DetectionUkg Ready notifies Stacksync of record changes through webhook events. UKG Webhooks for select events (employee.created, employee.updated, account/org changes) with HMAC signing.

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

Rate-limit considerations

  • Ukg Ready: Rate limits apply over roughly a 1-minute window and return HTTP 429 when exceeded (back off / exponential retry); UKG Webhooks run on a tiered quota with a free tier around 10,000 event notifications per month and 14-day event retention.
