Why teams connect Google Cloud Spanner and Ukg Pro

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

Ukg Pro is the system of record for the people side of the business — employees, candidates, roles, and the org structure around them. Google Cloud Spanner is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Time & Attendance (UTA), Employee (Person Details), Employment Details, Job / Position History in Ukg Pro need to exist as queryable Tables, Rows, Interleaved tables, Secondary indexes in Google Cloud Spanner 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 Tables, Rows, Interleaved tables, Secondary indexes in Google Cloud Spanner with Time & Attendance (UTA), Employee (Person Details), Employment Details, Job / Position History in Ukg Pro field by field, in real time. You decide which system owns which fields — Ukg Pro 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 Consolidate data from a globally distributed Spanner deployment into regional business systems.
  • 02 Push billing or entitlement changes from finance tools into Spanner tables the application reads at runtime.
  • 03 Two-way sync of Employee and Job Details (position, department, supervisor, location, cost center) into Postgres so provisioning, internal apps, and analytics read current worker and org data in SQL while HR edits in UKG Pro.
  • 04 Push new hires (Employee, Employment, Job) into an ERP, IdP, or app database when onboarding completes so account, cost-center, and payroll setup fire on hire instead of manual report exports.

Common sync patterns

Org and structure stay aligned

Groups, departments, managers, and reporting lines from Ukg Pro stay consistent in Google Cloud Spanner, so hierarchy-driven logic and permissions don't drift.

Computed and operational fields flow back

Values assembled or corrected in Google Cloud Spanner write onto the matching record in Ukg Pro where those fields are writable, keeping the people system enriched.

Mirror people records into the database

Records maintained in Ukg Pro land as queryable Tables, Rows, Interleaved tables, Secondary indexes in Google Cloud Spanner, so internal apps and dashboards read live data instead of a periodic export.

What you can sync between Google Cloud Spanner and Ukg Pro

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.

Google Cloud Spanner objects Ukg Pro objects How this pairing syncs
Rows The unit of read and write in each sync cycle, keyed by primary key. Configuration Setup (Code Tables) Reference data such as jobs, locations, positions, earnings, and deduction codes; used to resolve and validate field values when mapping records during sync. Rows is specific to Google Cloud Spanner and Configuration Setup (Code Tables) to Ukg Pro — each maps to any object or custom field on the other side.
Interleaved tables Child rows physically co-located with parents; synced as related records. Time & Attendance (UTA) Timekeeping and worked-hours data exposed by the UTA services; synced into scheduling, payroll, or workforce-analytics databases. Interleaved tables is specific to Google Cloud Spanner and Time & Attendance (UTA) to Ukg Pro — each maps to any object or custom field on the other side.
Secondary indexes Used to make incremental read queries efficient on non-key columns. Employee (Person Details) Core worker record with demographics and identifiers; read by listing employee IDs then fetching each profile, and created on hire via the personnel/onboarding endpoints. Secondary indexes is specific to Google Cloud Spanner and Employee (Person Details) to Ukg Pro — each maps to any object or custom field on the other side.
Change streams Capture inserts, updates, and deletes for log-style change data capture. Employment Details Employment status, hire and service dates, and company assignment; the record that drives active/terminated state for provisioning downstream. Change streams is specific to Google Cloud Spanner and Employment Details to Ukg Pro — each maps to any object or custom field on the other side.
Views Read-only projections useful for shaping data before it leaves Spanner. Job / Position History Effective-dated job, position, department, supervisor, location, and cost center; the most-synced record for org charts, provisioning, and analytics. Views is specific to Google Cloud Spanner and Job / Position History to Ukg Pro — each maps to any object or custom field on the other side.
Databases Top-level containers that scope schema and sync configuration. Compensation Details Effective-dated pay rate and salary; usually read into a warehouse for comp reporting and writable as new dated changes through the compensation endpoints. Databases is specific to Google Cloud Spanner and Compensation Details to Ukg Pro — each maps to any object or custom field on the other side.

How changes propagate between Google Cloud Spanner and Ukg Pro

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.

Google Cloud Spanner Ukg Pro Sub-second propagation

DetectionChanges in Google Cloud Spanner are captured at the source via change data capture — no polling loop against its API. Change streams (log-style CDC), or timestamp-based polling queries.

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

Ukg Pro Google Cloud Spanner Sub-second propagation

DetectionUkg Pro notifies Stacksync of record changes through webhook events. No CDC stream.

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

Rate-limit considerations

  • Google Cloud Spanner: Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.
  • Ukg Pro: An API gateway throttles calls per client over a rolling window (typically per minute); UKG does not publish exact numeric thresholds. Exceeding the limit returns HTTP 429, and UKG recommends a roughly one-second looping backoff before resuming (a Retry-After header is not yet standard). Reads are offset-paginated.

Google Cloud Spanner

Capabilities

Ukg Pro

Integration surface
REST API (UKG Pro HCM REST services) with separate Onboarding and Recruiting REST APIs, plus legacy SOAP-based UKG Pro Web Services
Authentication
Core HCM REST APIs use HTTP Basic authentication with a dedicated web service account, plus a Customer API Key and a User API Key sent as headers (found under System Configuration > Security > Service Account Administration); the Onboarding and Recruiting REST APIs instead require a bearer Authorization Token from the token endpoint.
Change detection
No CDC stream. UKG Pro publishes Pro HCM Webhook Events for changes such as new hire, employee and job detail changes, termination, and PTO, which Stacksync subscribes to for near-real-time triggers; bulk and historical loads use paged reads with each service's modified-since filters.
Capabilities

Rate limits
An API gateway throttles calls per client over a rolling window (typically per minute); UKG does not publish exact numeric thresholds. Exceeding the limit returns HTTP 429, and UKG recommends a roughly one-second looping backoff before resuming (a Retry-After header is not yet standard). Reads are offset-paginated.
