Why teams connect MotherDuck and Oracle Fusion Cloud HCM

Land the people and organization records from Oracle Fusion Cloud HCM in MotherDuck as live tables for workforce reporting, without extract jobs, and write computed results back where Oracle Fusion Cloud HCM can use them.

Workforce data is some of the most requested data in the warehouse and some of the most awkward to move: the record types are many, the fields carry sensitive personal information, the APIs are strict, and hand-built extract jobs go stale or break quietly. Whether Oracle Fusion Cloud HCM is the system of record for employees and payroll, for candidates and applications, or for learners and course completions, the reporting belongs in MotherDuck next to everything else the company measures.

Stacksync syncs Assignments, Jobs, Positions, Departments (Organizations) from Oracle Fusion Cloud HCM into tables in MotherDuck continuously, handling API limits and schema drift as they come. The connection is bi-directional, so values computed in MotherDuck, such as headcount rollups, cost allocations, or attrition risk flags, can be written back to fields in Oracle Fusion Cloud HCM where the HR team acts on them. You configure which records and fields cross over, and in which direction, instead of maintaining pipeline code.

Common use cases

  • 01 Share curated, synced datasets with other teams through read-only database shares
  • 02 Land CRM and operational database records in MotherDuck so a small team gets warehouse-style analytics without cluster management
  • 03 Two-way sync Workers and Assignments with an operational Postgres so internal apps read reporting lines, departments, and locations in SQL while HR keeps mastering data in Oracle HCM.
  • 04 Provision identities and app access downstream when an Atom new-hire or termination feed event fires, joining Workers, Assignments, Departments, and Locations.

Common sync patterns

Fresh data instead of last night's load

Because changes stream continuously, reports query current workforce data rather than waiting for an overnight load window to finish.

Queryable history for planning and audit

A continuously synced copy in MotherDuck gives you a durable, queryable record of how Oracle Fusion Cloud HCM's records change over time, for headcount planning and audit questions.

Write-back of computed values

Segments, rollups, or risk flags computed in MotherDuck sync back onto the matching records in Oracle Fusion Cloud HCM, where the HR team sees them in the system they already use.

What you can sync between MotherDuck and Oracle Fusion Cloud HCM

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.

MotherDuck objects Oracle Fusion Cloud HCM objects How this pairing syncs
Database Shares Read-only copies of a database shared with other users or teams. Departments (Organizations) Org-structure records that define cost centers and reporting lines; typically mastered in HCM and read into other systems. Database Shares is specific to MotherDuck and Departments (Organizations) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries. Locations Physical work locations referenced by assignments; synced so downstream provisioning and directory tools resolve the same location codes. Attached Local DuckDB Databases is specific to MotherDuck and Locations to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes. Grades and Salaries Grade, grade-rate, and worker compensation records; usually read out for compensation and headcount analytics, and written back for corrections. Databases is specific to MotherDuck and Grades and Salaries to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Schemas Namespaces within a database used to organize synced tables. Absences (workerAbsenceEntries) Time-off and leave entries; synced into scheduling or workforce-management databases for coverage planning. Schemas is specific to MotherDuck and Absences (workerAbsenceEntries) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Tables The main landing target for synced records and source for analysis. Workers (publicWorkers) Person master with personNumber, names, national IDs, and work relationships; synced two-way via the /workers resource, which replaced the desupported /emps resource. Tables is specific to MotherDuck and Workers (publicWorkers) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Views Modeled projections used as outbound sync sources. Assignments Child of a worker's work relationship carrying job, position, department, location, grade, and manager; effective-dated, so writes go through PATCH with an effective date. Views is specific to MotherDuck and Assignments to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.

How changes propagate between MotherDuck and Oracle Fusion Cloud HCM

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.

MotherDuck Oracle Fusion Cloud HCM Interval-based propagation

DetectionStacksync polls MotherDuck for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

DeliveryEach detected change is written to Oracle Fusion Cloud HCM through its API, with automatic retries and rate-limit backoff.

Oracle Fusion Cloud HCM MotherDuck Sub-second propagation

DetectionChanges in Oracle Fusion Cloud HCM are captured at the source via change data capture — no polling loop against its API. Atom feeds expose changes-only feeds for key events (new hire, termination, assignment change).

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

Rate-limit considerations

  • MotherDuck: Subject to the platform's compute and concurrency limits rather than per-request API rate limits.
  • Oracle Fusion Cloud HCM: Oracle publishes no fixed per-tenant REST rate limit; pages are capped via limit/offset and Oracle recommends client-side throttling, backoff, and using HDL for mass loads rather than transactional REST.
