Why teams connect Lever and YugabyteDB

Put your workforce data where your apps can reach it: YugabyteDB 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. YugabyteDB is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Interviews, Notes and Contacts, Opportunities, Postings in Lever need to exist as queryable CDC Streams, Databases and Keyspaces, Tables, Indexes in YugabyteDB 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 CDC Streams, Databases and Keyspaces, Tables, Indexes in YugabyteDB with Interviews, Notes and Contacts, Opportunities, Postings 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 Run log-based CDC from YugabyteDB tables into a warehouse for analytics without batch dumps.
  • 02 Two-way sync between YugabyteDB application tables and a CRM so product data and account records stay consistent.
  • 03 When an Opportunity is marked hired, write the candidate and its Offer into an HRIS or onboarding system to start employee provisioning.
  • 04 Consolidate Feedback, Interviews, and Notes into a warehouse for interviewer scorecard and time-to-fill reporting.

Common sync patterns

Org and structure stay aligned

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

Computed and operational fields flow back

Values assembled or corrected in YugabyteDB 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 CDC Streams, Databases and Keyspaces, Tables, Indexes in YugabyteDB, so internal apps and dashboards read live data instead of a periodic export.

What you can sync between Lever and YugabyteDB

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.

Lever objects YugabyteDB objects How this pairing syncs
Users Lever team members (recruiters, hiring managers) with configurable roles; can be created via POST /users, deactivated, and reactivated through the API. CDC Streams Change streams over the storage-layer WAL consumed through logical replication or Debezium-compatible connectors. Users is specific to Lever and CDC Streams to YugabyteDB — each maps to any object or custom field on the other side.
Stages Pipeline stage definitions that Opportunities move through; read to model funnel state and stage transitions in a database. Databases and Keyspaces Top-level containers for the YSQL (Postgres-style) and YCQL (Cassandra-style) APIs respectively. Stages is specific to Lever and Databases and Keyspaces to YugabyteDB — each maps to any object or custom field on the other side.
Feedback Interview feedback and scorecard forms attached to Opportunities; created via POST /opportunities/:id/feedback and consolidated into a warehouse for interviewer analytics. Tables Distributed SQL tables split into tablets; the primary read and write targets. Feedback is specific to Lever and Tables to YugabyteDB — each maps to any object or custom field on the other side.
Interviews Scheduled interview panel events with times and interviewers; read for scheduling reporting and time-to-hire metrics, and creatable via the panels endpoint. Indexes Global secondary indexes maintained transactionally alongside table writes. Interviews is specific to Lever and Indexes to YugabyteDB — each maps to any object or custom field on the other side.
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. Materialized Views Precomputed query results available in YSQL for read-side shaping. Notes and Contacts is specific to Lever and Materialized Views to YugabyteDB — each maps to any object or custom field on the other side.
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. Schemas Postgres-style namespaces in YSQL used to organize synced data. Opportunities is specific to Lever and Schemas to YugabyteDB — each maps to any object or custom field on the other side.

How changes propagate between Lever and YugabyteDB

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.

Lever YugabyteDB 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 YugabyteDB as a row-level write, with types converted between the two schemas.

YugabyteDB Lever Sub-second propagation

DetectionChanges in YugabyteDB are captured at the source via change data capture — no polling loop against its API. Native CDC from the write-ahead log via PostgreSQL logical replication or Debezium-compatible connectors.

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

Rate-limit considerations

  • 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.
  • YugabyteDB: No API rate limits; throughput scales with cluster nodes and tablet distribution.
