Why teams connect Dremio and Oracle Fusion Cloud HCM

Land the people and organization records from Oracle Fusion Cloud HCM in Dremio 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 Dremio next to everything else the company measures.

Stacksync syncs Grades and Salaries, Absences (workerAbsenceEntries), Workers (publicWorkers), Assignments from Oracle Fusion Cloud HCM into tables in Dremio continuously, handling API limits and schema drift as they come. The connection is bi-directional, so values computed in Dremio, 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 Reverse-ETL aggregates computed over lake data out to CRMs and finance tools for business users.
  • 02 Publish operational database tables into Iceberg via Dremio so the lakehouse reflects current application state.
  • 03 Provision identities and app access downstream when an Atom new-hire or termination feed event fires, joining Workers, Assignments, Departments, and Locations.
  • 04 Replicate Grades and Salaries into a warehouse for compensation and headcount analytics without exporting HDL files.

Common sync patterns

Write-back of computed values

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

HR data in the warehouse, minus the pipeline

People and organization records from Oracle Fusion Cloud HCM arrive in Dremio as queryable tables, current within seconds instead of a day behind, replacing hand-built extract jobs.

Headcount and cost joined with everything else

Analysts combine Oracle Fusion Cloud HCM's workforce records with finance, product, or operational data already in Dremio for reporting the HR system cannot produce on its own.

What you can sync between Dremio 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.

Dremio objects Oracle Fusion Cloud HCM objects How this pairing syncs
Jobs Query execution records useful for monitoring sync workloads. Jobs Job catalog reference data; commonly read out to align titles and job codes in a warehouse or written to keep downstream systems consistent. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Apache Iceberg tables Lakehouse tables supporting DML and snapshot metadata usable for incremental reads. 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. Apache Iceberg tables is specific to Dremio and Assignments to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Spaces and folders Namespaces that organize virtual datasets and govern access. Positions Position-management records used where positions control headcount; synced to keep vacancy and reporting structures aligned with finance/ERP. Spaces and folders is specific to Dremio and Positions to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Reflections Materialized accelerations that make repeated extraction queries cheaper. Departments (Organizations) Org-structure records that define cost centers and reporting lines; typically mastered in HCM and read into other systems. Reflections is specific to Dremio and Departments (Organizations) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Sources Connected storage and database systems (S3, ADLS, relational databases) Dremio queries in place. Locations Physical work locations referenced by assignments; synced so downstream provisioning and directory tools resolve the same location codes. Sources is specific to Dremio and Locations to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Physical datasets Tables and files promoted from sources; the raw data a sync ultimately reads. Grades and Salaries Grade, grade-rate, and worker compensation records; usually read out for compensation and headcount analytics, and written back for corrections. Physical datasets is specific to Dremio and Grades and Salaries to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.

How changes propagate between Dremio 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.

Dremio Oracle Fusion Cloud HCM Interval-based propagation

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

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

Oracle Fusion Cloud HCM Dremio 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 Dremio as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Dremio: Bounded by engine capacity and workload management rather than 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.
