Why teams connect DuckDB and Ukg Pro

Put your workforce data where your apps can reach it: DuckDB 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. DuckDB is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Payroll (Pay Statements, Direct Deposit, Earnings), Terminations, Configuration Setup (Code Tables), Time & Attendance (UTA) in Ukg Pro need to exist as queryable Database files, Schemas, Tables, Views in DuckDB 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 Database files, Schemas, Tables, Views in DuckDB with Payroll (Pay Statements, Direct Deposit, Earnings), Terminations, Configuration Setup (Code Tables), Time & Attendance (UTA) 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 Use DuckDB as a transform step: read synced Parquet exports, aggregate with SQL, and write results back to an operational database.
  • 02 Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.
  • 03 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.
  • 04 Replicate Compensation and pay-statement / earnings history into a warehouse for headcount, labor-cost, and payroll reporting without manual BI exports.

Common sync patterns

Mirror people records into the database

Records maintained in Ukg Pro land as queryable Database files, Schemas, Tables, Views in DuckDB, 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

Payroll (Pay Statements, Direct Deposit, Earnings), Terminations, Configuration Setup (Code Tables), Time & Attendance (UTA) replicate into DuckDB where they join operational tables, so headcount, roles, and status reports run on the live state without manual pulls.

What you can sync between DuckDB 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.

DuckDB objects Ukg Pro objects How this pairing syncs
Schemas Namespaces within a database used to organize tables in sync outputs. Terminations Termination transactions posted with a terminationDate and a reason code that must match the tenant's configured reason table; drives account deprovisioning. Schemas is specific to DuckDB and Terminations to Ukg Pro — each maps to any object or custom field on the other side.
Tables Columnar tables created via SQL; the destination for materialized sync data. 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. Tables is specific to DuckDB and Configuration Setup (Code Tables) to Ukg Pro — each maps to any object or custom field on the other side.
Views SQL views used to shape or filter data for downstream consumers. Time & Attendance (UTA) Timekeeping and worked-hours data exposed by the UTA services; synced into scheduling, payroll, or workforce-analytics databases. Views is specific to DuckDB and Time & Attendance (UTA) to Ukg Pro — each maps to any object or custom field on the other side.
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. 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. External files (Parquet/CSV/JSON) is specific to DuckDB and Employee (Person Details) to Ukg Pro — each maps to any object or custom field on the other side.
Attached databases Additional database files or external systems attached into one session for cross-source queries. Employment Details Employment status, hire and service dates, and company assignment; the record that drives active/terminated state for provisioning downstream. Attached databases is specific to DuckDB and Employment Details to Ukg Pro — each maps to any object or custom field on the other side.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Job / Position History Effective-dated job, position, department, supervisor, location, and cost center; the most-synced record for org charts, provisioning, and analytics. Database files is specific to DuckDB and Job / Position History to Ukg Pro — each maps to any object or custom field on the other side.

How changes propagate between DuckDB 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.

DuckDB Ukg Pro Interval-based propagation

DetectionStacksync polls DuckDB for changes on an incremental schedule, reading only records changed since the previous pass. Polling or full re-reads.

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

Ukg Pro DuckDB Sub-second propagation

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

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

Rate-limit considerations

  • DuckDB: No API rate limits; throughput is bounded by local compute and I/O.
  • 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.

How the DuckDB and Ukg Pro connectors work

DuckDB

Integration surface
In-process SQL engine via client libraries (Python, Node.js, JDBC, CLI); no server or network API by default
Authentication
None built in; access control is file-system level (MotherDuck adds token auth for its hosted service)
Change detection
Polling or full re-reads; no change feed or transaction log API
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by local compute and I/O

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.
