Why teams connect SingleStore and Smartrecruiters

Put your workforce data where your apps can reach it: SingleStore 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. SingleStore is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Jobs, Job Postings, Interviews, Offers in Smartrecruiters need to exist as queryable Views, Reference Tables, Pipelines, Stored Procedures in SingleStore 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 Views, Reference Tables, Pipelines, Stored Procedures in SingleStore with Jobs, Job Postings, Interviews, Offers 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 Mirror CRM and SaaS objects into SingleStore tables to serve low-latency operational dashboards.
  • 02 Sync results of real-time analytical queries back into business tools where teams act on them.
  • 03 Two-way sync Candidates and Applications with Postgres so recruiting-ops apps read and update hiring status, tags, and custom fields in SQL while recruiters keep working in SmartRecruiters.
  • 04 Write enriched or sourced Candidates from external sourcing tools into SmartRecruiters and keep contact fields refreshed as data changes.

Common sync patterns

Mirror people records into the database

Records maintained in Smartrecruiters land as queryable Views, Reference Tables, Pipelines, Stored Procedures in SingleStore, so internal apps and dashboards read live data instead of a periodic export.

One directory of record

When a person record is added, changed, or deactivated in either system, the matching row in the other stays current, ending dual maintenance.

Reporting and analytics on current data

Jobs, Job Postings, Interviews, Offers replicate into SingleStore where they join operational tables, so headcount, roles, and status reports run on the live state without manual pulls.

What you can sync between SingleStore 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.

SingleStore objects Smartrecruiters objects How this pairing syncs
Databases The connection target containing the tables a sync addresses. 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. Databases is specific to SingleStore and Jobs to Smartrecruiters — each maps to any object or custom field on the other side.
Tables (rowstore and columnstore) Primary read/write target; storage type affects whether a table suits point lookups or scans. 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). Tables (rowstore and columnstore) is specific to SingleStore and Job Postings to Smartrecruiters — each maps to any object or custom field on the other side.
Views Read-only projections used as curated sync sources. Interviews Interview types, timeslots, templates, and scheduled interviews with interviewers and times; created, updated, and read for scheduling and interviewer-load analytics. Views is specific to SingleStore and Interviews to Smartrecruiters — each maps to any object or custom field on the other side.
Reference Tables Small tables replicated to every node, often used for dimension data in syncs. 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). Reference Tables is specific to SingleStore and Offers to Smartrecruiters — each maps to any object or custom field on the other side.
Pipelines Native ingestion jobs from Kafka or object storage that coexist with external syncs. Users Company users (recruiters, hiring managers) with roles, access groups, and activation state; read and written via the User Management API. Pipelines is specific to SingleStore and Users to Smartrecruiters — each maps to any object or custom field on the other side.
Stored Procedures Existing logic sometimes invoked on write paths. Approvals Approval requests for jobs and offers; requests can be created, retrieved as pending, commented on, and approved or rejected via the Approvals API. Stored Procedures is specific to SingleStore and Approvals to Smartrecruiters — each maps to any object or custom field on the other side.

How changes propagate between SingleStore 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.

SingleStore Smartrecruiters Interval-based propagation

DetectionStacksync polls SingleStore for changes on an incremental schedule, reading only records changed since the previous pass. Polling on timestamp or watermark columns.

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

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

Rate-limit considerations

  • SingleStore: No API rate limits; throughput is bounded by workspace or cluster size.
  • 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.
