Why teams connect Apache Pinot and Smartrecruiters

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

Stacksync syncs Approvals, Candidates, Applications, Jobs from Smartrecruiters into tables in Apache Pinot continuously, handling API limits and schema drift as they come. The connection is bi-directional, so values computed in Apache Pinot, such as headcount rollups, cost allocations, or attrition risk flags, can be written back to fields in Smartrecruiters 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 Sync Pinot aggregates into a warehouse to join low-latency metrics with modeled historical data.
  • 02 Serve user-facing analytics from Pinot while syncing daily rollups to finance and ops tools.
  • 03 Export Interviews and Offers to a data warehouse to analyze interviewer load, offer-acceptance rates, and hiring outcomes.
  • 04 Subscribe to the Webhooks API to react to new applications and status changes in near real time across downstream systems.

Common sync patterns

Write-back of computed values

Segments, rollups, or risk flags computed in Apache Pinot sync back onto the matching records in Smartrecruiters, 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 Smartrecruiters arrive in Apache Pinot 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 Smartrecruiters's workforce records with finance, product, or operational data already in Apache Pinot for reporting the HR system cannot produce on its own.

What you can sync between Apache Pinot and Smartrecruiters

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 Pinot objects Smartrecruiters objects How this pairing syncs
Tenants Logical groupings that isolate workloads on shared clusters. Candidates Person records with contact details, tags, attachments, custom properties, and consent; created, updated, and searched via the Candidates API, often populated from sourcing or enrichment pipelines. Tenants is specific to Apache Pinot and Candidates to Smartrecruiters — each maps to any object or custom field on the other side.
Tables The queryable unit, defined as offline, real-time, or hybrid; the main read target. Applications Links a Candidate to a Job and carries the current hiring status and source; created and advanced through statuses (screening, interview, offer, hired, rejected) via the Application API. Tables is specific to Apache Pinot and Applications to Smartrecruiters — each maps to any object or custom field on the other side.
Schemas Column definitions (dimensions, metrics, time columns) mapped during integration setup. Jobs Requisitions (positions) with openings, departments, locations, and hiring team; created, patched, and read out for requisition and time-to-fill reporting via the Jobs API. Schemas is specific to Apache Pinot and Jobs to Smartrecruiters — each maps to any object or custom field on the other side.
Segments Immutable data files that batch ingestion uploads and the cluster serves. Job Postings Job ads and publications pushed to the career site and job boards; created and managed via the job publication endpoints (rate-limited to 2 requests/sec). Segments is specific to Apache Pinot and Job Postings to Smartrecruiters — each maps to any object or custom field on the other side.
Real-time Tables Tables fed continuously from streams like Kafka, including upsert-enabled tables. Interviews Interview types, timeslots, templates, and scheduled interviews with interviewers and times; created, updated, and read for scheduling and interviewer-load analytics. Real-time Tables is specific to Apache Pinot and Interviews to Smartrecruiters — each maps to any object or custom field on the other side.
Offline Tables Batch-loaded tables merged with real-time data at query time. Offers Offer records tied to an Application with status, custom offer fields, and offer documents; readable and writable, commonly synced to an HRIS on hire (documents endpoint limited to 2 requests/sec). Offline Tables is specific to Apache Pinot and Offers to Smartrecruiters — each maps to any object or custom field on the other side.

How changes propagate between Apache Pinot and Smartrecruiters

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 Pinot Smartrecruiters Interval-based propagation

DetectionStacksync polls Apache Pinot for changes on an incremental schedule, reading only records changed since the previous pass. Data enters Pinot via streaming ingestion or segment upload, not row-level writes.

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

Smartrecruiters Apache Pinot Sub-second propagation

DetectionSmartrecruiters notifies Stacksync of record changes through webhook events. Webhooks API — subscribe to events (new application, candidate updated, status changed) delivered with a signing secret and retrievable callback logs.

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

Rate-limit considerations

  • Apache Pinot: No fixed API quotas; query throughput depends on broker and server sizing.
  • Smartrecruiters: Per API credential: most endpoints allow up to 10 requests/sec (job publication and offer documents 2/sec), plus a concurrency limiter of up to 8 simultaneous requests (GET /candidates capped at 1). Exceeding returns 429; responses carry X-RateLimit-Limit/Remaining and concurrent-limit headers.
