Why teams connect Smartrecruiters and VoltDB

Put your workforce data where your apps can reach it: VoltDB and Smartrecruiters share the same people, positions, and org structure in real time.

Smartrecruiters is the system of record for the people side of the business — employees, candidates, roles, and the org structure around them. VoltDB is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Offers, Users, Approvals, Candidates in Smartrecruiters need to exist as queryable Stored Procedures, Materialized Views, Streams, Export Targets and Topics in VoltDB before an app can act on them. When that bridge is a nightly export or a hand-run CSV, every downstream system spends the day working from a roster that has already moved on.

Stacksync syncs Stored Procedures, Materialized Views, Streams, Export Targets and Topics in VoltDB with Offers, Users, Approvals, Candidates in Smartrecruiters field by field, in real time. You decide which system owns which fields — Smartrecruiters typically owns identity and org attributes, while operational or computed values can flow back the other way — and Stacksync keeps every copy consistent, matching records on a stable key and resolving conflicts by rules you set.

The result is one live picture of the workforce on both sides: HR keeps its source of truth, and the database keeps a current mirror that internal apps, reports, and access controls can trust without a batch window in between.

Common use cases

  • 01 Keep product, plan, or entitlement state consistent between VoltDB and back-office systems.
  • 02 Push aggregates from VoltDB materialized views into dashboards or operational tools.
  • 03 Write enriched or sourced Candidates from external sourcing tools into SmartRecruiters and keep contact fields refreshed as data changes.
  • 04 Stream Jobs and Job Postings into a reporting database for requisition, funnel, and time-to-fill dashboards.

Common sync patterns

Reporting and analytics on current data

Offers, Users, Approvals, Candidates replicate into VoltDB where they join operational tables, so headcount, roles, and status reports run on the live state without manual pulls.

Org and structure stay aligned

Groups, departments, managers, and reporting lines from Smartrecruiters stay consistent in VoltDB, so hierarchy-driven logic and permissions don't drift.

Computed and operational fields flow back

Values assembled or corrected in VoltDB write onto the matching record in Smartrecruiters where those fields are writable, keeping the people system enriched.

What you can sync between Smartrecruiters and VoltDB

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.

Smartrecruiters objects VoltDB objects How this pairing syncs
Approvals Approval requests for jobs and offers; requests can be created, retrieved as pending, commented on, and approved or rejected via the Approvals API. Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources. Approvals is specific to Smartrecruiters and Materialized Views to VoltDB — each maps to any object or custom field on the other side.
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. Streams Insert-only constructs that feed the export subsystem with committed rows. Candidates is specific to Smartrecruiters and Streams to VoltDB — each maps to any object or custom field on the other side.
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. Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks. Applications is specific to Smartrecruiters and Export Targets and Topics to VoltDB — each maps to any object or custom field on the other side.
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. Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target. Jobs is specific to Smartrecruiters and Partitioned Tables to VoltDB — each maps to any object or custom field on the other side.
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). Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data. Job Postings is specific to Smartrecruiters and Replicated Tables to VoltDB — each maps to any object or custom field on the other side.
Interviews Interview types, timeslots, templates, and scheduled interviews with interviewers and times; created, updated, and read for scheduling and interviewer-load analytics. Stored Procedures Precompiled transactional units that serve as the primary write interface. Interviews is specific to Smartrecruiters and Stored Procedures to VoltDB — each maps to any object or custom field on the other side.

How changes propagate between Smartrecruiters and VoltDB

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.

Smartrecruiters VoltDB 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 VoltDB as a row-level write, with types converted between the two schemas.

VoltDB Smartrecruiters Interval-based propagation

DetectionStacksync polls VoltDB for changes on an incremental schedule, reading only records changed since the previous pass. Export streams and topics push committed changes to configured targets.

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

Rate-limit considerations

  • 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.
  • VoltDB: No API rate limits; throughput is bounded by partition count and cluster sizing.
