Why teams connect Greenhouse and IBM Netezza

Land the people and organization records from Greenhouse in IBM Netezza as live tables for workforce reporting, without extract jobs, and write computed results back where Greenhouse 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 Greenhouse is the system of record for employees and payroll, for candidates and applications, or for learners and course completions, the reporting belongs in IBM Netezza next to everything else the company measures.

Stacksync syncs Applications, Jobs, Offers, Scorecards from Greenhouse into tables in IBM Netezza continuously, handling API limits and schema drift as they come. The connection is bi-directional, so values computed in IBM Netezza, such as headcount rollups, cost allocations, or attrition risk flags, can be written back to fields in Greenhouse 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 Publish segments and scores computed in Netezza back to operational tools where business teams act on them.
  • 02 Keep Netezza and a cloud warehouse in sync during a platform migration so reporting stays consistent.
  • 03 Export Scorecards and Scheduled Interviews to a data warehouse to analyze interviewer load and interview outcomes.
  • 04 Two-way sync Candidates and Applications with Postgres so recruiting-ops apps read and update stage, status, and custom fields in SQL while recruiters stay in Greenhouse.

Common sync patterns

HR data in the warehouse, minus the pipeline

People and organization records from Greenhouse arrive in IBM Netezza 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 Greenhouse's workforce records with finance, product, or operational data already in IBM Netezza for reporting the HR system cannot produce on its own.

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.

What you can sync between Greenhouse and IBM Netezza

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.

Greenhouse objects IBM Netezza objects How this pairing syncs
Jobs Requisitions with openings, hiring team, departments, and offices; created and patched via Harvest, read out for funnel and time-to-fill reporting. Sequences Key generators referenced when writing new rows. Jobs is specific to Greenhouse and Sequences to IBM Netezza — each maps to any object or custom field on the other side.
Offers Offer records tied to an Application with status and custom offer fields; readable and patchable, commonly synced to HRIS on hire. External tables File-backed load/unload paths used for bulk movement alongside row-level syncs. Offers is specific to Greenhouse and External tables to IBM Netezza — each maps to any object or custom field on the other side.
Scorecards Interviewer feedback and ratings tied to interviews; read-only in Harvest, exported to a warehouse for interview analytics. Databases Top-level containers that scope a sync connection. Scorecards is specific to Greenhouse and Databases to IBM Netezza — each maps to any object or custom field on the other side.
Scheduled Interviews Interview events with interviewers, times, and rooms; full create/update/delete support for calendar and reporting syncs. Schemas Namespace tables within a database. Scheduled Interviews is specific to Greenhouse and Schemas to IBM Netezza — each maps to any object or custom field on the other side.
Users Greenhouse users (recruiters, hiring managers); read and written, and referenced by the On-Behalf-Of header on every write. Tables Distributed tables mapped directly to sync targets. Users is specific to Greenhouse and Tables to IBM Netezza — each maps to any object or custom field on the other side.
Departments and Offices Org structure attached to Jobs; read and written to keep reporting hierarchies aligned with an HRIS or warehouse. Views Read-only projections used to shape outbound data. Departments and Offices is specific to Greenhouse and Views to IBM Netezza — each maps to any object or custom field on the other side.

How changes propagate between Greenhouse and IBM Netezza

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.

Greenhouse IBM Netezza Sub-second propagation

DetectionGreenhouse notifies Stacksync of record changes through webhook events. HMAC-SHA256 signed webhooks for candidate, application, job, and interview events, plus polling list endpoints with created_after / updated_after /.

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

IBM Netezza Greenhouse Interval-based propagation

DetectionStacksync polls IBM Netezza for changes on an incremental schedule, reading only records changed since the previous pass. Polling with timestamp or key-based cursors.

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

Rate-limit considerations

  • Greenhouse: Harvest enforces a per-integration limit over a rolling 10-second window (X-RateLimit-Limit, commonly 50 requests / 10s for approved integrations); responses carry X-RateLimit-Remaining and, on a 429, X-RateLimit-Reset and Retry-After.
  • IBM Netezza: Bounded by appliance or instance capacity and concurrency settings.
