Why teams connect Citus and Smartrecruiters

Put your workforce data where your apps can reach it: Citus 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. Citus 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 Sequences, Distributed tables, Reference tables, Local tables in Citus 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 Sequences, Distributed tables, Reference tables, Local tables in Citus 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 Sync high-volume event or tenant data from a Citus cluster into a warehouse for cross-tenant analytics.
  • 02 Write CRM or billing records into reference tables so distributed queries can join operational context locally on every node.
  • 03 Subscribe to the Webhooks API to react to new applications and status changes in near real time across downstream systems.
  • 04 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.

Common sync patterns

Org and structure stay aligned

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

Computed and operational fields flow back

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

Mirror people records into the database

Records maintained in Smartrecruiters land as queryable Sequences, Distributed tables, Reference tables, Local tables in Citus, so internal apps and dashboards read live data instead of a periodic export.

What you can sync between Citus 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.

Citus objects Smartrecruiters objects How this pairing syncs
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. 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. Reference tables is specific to Citus and Candidates to Smartrecruiters — each maps to any object or custom field on the other side.
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. 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. Local tables is specific to Citus and Applications to Smartrecruiters — each maps to any object or custom field on the other side.
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. 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 Citus and Jobs to Smartrecruiters — each maps to any object or custom field on the other side.
Views Curated projections over distributed data, often used as read-only sync sources. 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). Views is specific to Citus and Job Postings to Smartrecruiters — each maps to any object or custom field on the other side.
Sequences Key generators that matter when external writes must not collide with application inserts. Interviews Interview types, timeslots, templates, and scheduled interviews with interviewers and times; created, updated, and read for scheduling and interviewer-load analytics. Sequences is specific to Citus and Interviews to Smartrecruiters — each maps to any object or custom field on the other side.
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. 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). Distributed tables is specific to Citus and Offers to Smartrecruiters — each maps to any object or custom field on the other side.

How changes propagate between Citus 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.

Citus Smartrecruiters Sub-second propagation

DetectionChanges in Citus are captured at the source via change data capture — no polling loop against its API. PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres.

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

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

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.
