Why teams connect CockroachDB and Lever

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

Lever is the system of record for the people side of the business — employees, candidates, roles, and the org structure around them. CockroachDB is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Requisitions, Offers, Users, Stages in Lever need to exist as queryable Schemas, Tables, Views, Indexes in CockroachDB 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 Schemas, Tables, Views, Indexes in CockroachDB with Requisitions, Offers, Users, Stages in Lever field by field, in real time. You decide which system owns which fields — Lever 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 Use changefeeds to propagate row changes from a multi-region cluster into a warehouse or search index.
  • 02 Keep reference data consistent between CockroachDB and regional application databases.
  • 03 Push Postings and Requisitions into an HRIS or warehouse to reconcile approved headcount against open roles.
  • 04 When an Opportunity is marked hired, write the candidate and its Offer into an HRIS or onboarding system to start employee provisioning.

Common sync patterns

Computed and operational fields flow back

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

Mirror people records into the database

Records maintained in Lever land as queryable Schemas, Tables, Views, Indexes in CockroachDB, 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.

What you can sync between CockroachDB and Lever

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.

CockroachDB objects Lever objects How this pairing syncs
Views Read-only projections used as curated sync sources. Interviews Scheduled interview panel events with times and interviewers; read for scheduling reporting and time-to-hire metrics, and creatable via the panels endpoint. Views is specific to CockroachDB and Interviews to Lever — each maps to any object or custom field on the other side.
Indexes Secondary indexes that keep sync lookup queries fast on key columns. Notes and Contacts Free-text Notes on Opportunities plus the underlying Contact (person) that dedupes multiple Opportunities; notes are posted via POST /opportunities/:id/notes and contact-level tags, sources, and links can be added back for attribution. Indexes is specific to CockroachDB and Notes and Contacts to Lever — each maps to any object or custom field on the other side.
Sequences ID generators that matter when writes originate from an external system. Opportunities The core pipeline record for a candidate applying to a role; replaced the deprecated Candidates endpoint. Created via POST /opportunities and updated (stage, archive, links, tags, sources, files) through the API, and synced two-way with a database or HRIS. Sequences is specific to CockroachDB and Opportunities to Lever — each maps to any object or custom field on the other side.
Changefeeds Built-in CDC streams that emit row-level changes to external sinks. Postings Job posting records with categories, apply URLs, workplace type, and requisition codes. Can be created via POST /postings and read into a warehouse for open-role reporting. Changefeeds is specific to CockroachDB and Postings to Lever — each maps to any object or custom field on the other side.
Databases Logical containers a sync connects to, addressed like PostgreSQL databases. Requisitions Headcount/requisition records with custom requisition fields, tied to Postings; read via GET /requisitions and synced to an HRIS to reconcile approved headcount against open roles. Databases is specific to CockroachDB and Requisitions to Lever — each maps to any object or custom field on the other side.
Schemas Namespaces within a database used to isolate synced tables from application tables. Offers Offer records attached to an Opportunity with status and offer-form fields; exposed read-only through GET /opportunities/:id/offers, so they sync outbound to an HRIS or onboarding system when a candidate reaches the offer stage. Schemas is specific to CockroachDB and Offers to Lever — each maps to any object or custom field on the other side.

How changes propagate between CockroachDB and Lever

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.

CockroachDB Lever Sub-second propagation

DetectionChanges in CockroachDB are captured at the source via change data capture — no polling loop against its API. CDC via changefeeds, which stream row-level changes.

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

Lever CockroachDB Sub-second propagation

DetectionLever notifies Stacksync of record changes through webhook events. Webhooks for candidate and application lifecycle events (applicationCreated, candidateStageChange, candidateArchiveStateChange, candidateHired,.

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

Rate-limit considerations

  • CockroachDB: No API rate limits in the SaaS sense; throughput is bounded by cluster capacity.
  • Lever: 10 requests/second per API key with a token-bucket burst to ~20/s; POSTs that create candidates/applications are throttled to roughly 2/second. Sustained overage returns 429 with Retry-After. List endpoints are cursor-paginated at up to 100 records per page.
