Why teams connect Apache Druid and Oracle Fusion Cloud HCM

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

Stacksync syncs Positions, Departments (Organizations), Locations, Grades and Salaries from Oracle Fusion Cloud HCM into tables in Apache Druid continuously, handling API limits and schema drift as they come. The connection is bi-directional, so values computed in Apache Druid, 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 Feed operational records into Druid via batch ingestion so analysts get interactive slice-and-dice on fresh data.
  • 02 Sync Druid query results into a warehouse to combine real-time aggregates with historical models.
  • 03 Keep Positions and Departments aligned between Oracle HCM and a finance/ERP system so cost centers and reporting structures match.
  • 04 Sync Absences (workerAbsenceEntries) into a scheduling or workforce-management database for coverage planning.

Common sync patterns

Write-back of computed values

Segments, rollups, or risk flags computed in Apache Druid 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 Apache Druid 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 Apache Druid for reporting the HR system cannot produce on its own.

What you can sync between Apache Druid 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.

Apache Druid objects Oracle Fusion Cloud HCM objects How this pairing syncs
Datasources The table-like unit of storage and querying, the main target of reads and ingestion. Locations Physical work locations referenced by assignments; synced so downstream provisioning and directory tools resolve the same location codes. Datasources is specific to Apache Druid and Locations to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Segments Time-partitioned immutable files that hold datasource data; ingestion produces them. Grades and Salaries Grade, grade-rate, and worker compensation records; usually read out for compensation and headcount analytics, and written back for corrections. Segments is specific to Apache Druid and Grades and Salaries to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Dimensions String and categorical columns used for filtering and grouping in synced queries. Absences (workerAbsenceEntries) Time-off and leave entries; synced into scheduling or workforce-management databases for coverage planning. Dimensions is specific to Apache Druid and Absences (workerAbsenceEntries) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Metrics Numeric columns, often pre-aggregated at ingestion via rollup. 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. Metrics is specific to Apache Druid and Workers (publicWorkers) to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Ingestion Supervisors Long-running specs that pull from streams like Kafka; the write path into Druid. 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. Ingestion Supervisors is specific to Apache Druid and Assignments to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.
Lookups Key-value mappings joined at query time, refreshable from external systems. Jobs Job catalog reference data; commonly read out to align titles and job codes in a warehouse or written to keep downstream systems consistent. Lookups is specific to Apache Druid and Jobs to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.

How changes propagate between Apache Druid 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.

Apache Druid Oracle Fusion Cloud HCM Interval-based propagation

DetectionStacksync polls Apache Druid for changes on an incremental schedule, reading only records changed since the previous pass. Data enters Druid through streaming or batch ingestion rather than row updates.

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

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

Rate-limit considerations

  • Apache Druid: No fixed API quotas; query concurrency is bounded by broker and historical node capacity.
  • 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.
