Why teams connect IBM Db2 and Lever

Put your workforce data where your apps can reach it: IBM Db2 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. IBM Db2 is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Stages, Feedback, Interviews, Notes and Contacts in Lever need to exist as queryable Stored Procedures, Sequences, Tablespaces, Databases in IBM Db2 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, Sequences, Tablespaces, Databases in IBM Db2 with Stages, Feedback, Interviews, Notes and Contacts 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 Expose Db2 records that back core business systems to a CRM so sales and support see order or account state.
  • 02 Sync SaaS data into Db2 tables that existing enterprise applications and reports already consume.
  • 03 Two-way sync Opportunities and their Stages between Lever and a Postgres database so recruiting ops and analysts query the pipeline in SQL while recruiters keep working in Lever.
  • 04 Push Postings and Requisitions into an HRIS or warehouse to reconcile approved headcount against open roles.

Common sync patterns

Org and structure stay aligned

Groups, departments, managers, and reporting lines from Lever stay consistent in IBM Db2, so hierarchy-driven logic and permissions don't drift.

Computed and operational fields flow back

Values assembled or corrected in IBM Db2 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 Stored Procedures, Sequences, Tablespaces, Databases in IBM Db2, so internal apps and dashboards read live data instead of a periodic export.

What you can sync between IBM Db2 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.

IBM Db2 objects Lever objects How this pairing syncs
Indexes Support fast key lookups on sync match columns. Stages Pipeline stage definitions that Opportunities move through; read to model funnel state and stage transitions in a database. Indexes is specific to IBM Db2 and Stages to Lever — each maps to any object or custom field on the other side.
Stored Procedures Existing business logic sometimes invoked as part of write paths. Feedback Interview feedback and scorecard forms attached to Opportunities; created via POST /opportunities/:id/feedback and consolidated into a warehouse for interviewer analytics. Stored Procedures is specific to IBM Db2 and Feedback to Lever — each maps to any object or custom field on the other side.
Sequences ID generation relevant when external systems insert rows. Interviews Scheduled interview panel events with times and interviewers; read for scheduling reporting and time-to-hire metrics, and creatable via the panels endpoint. Sequences is specific to IBM Db2 and Interviews to Lever — each maps to any object or custom field on the other side.
Tablespaces Physical storage layout that operators consider when adding synced tables. 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. Tablespaces is specific to IBM Db2 and Notes and Contacts to Lever — each maps to any object or custom field on the other side.
Databases The connection target; each database holds the schemas a sync addresses. 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. Databases is specific to IBM Db2 and Opportunities to Lever — each maps to any object or custom field on the other side.
Schemas Namespaces separating synced data from application and system objects. 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. Schemas is specific to IBM Db2 and Postings to Lever — each maps to any object or custom field on the other side.

How changes propagate between IBM Db2 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.

IBM Db2 Lever Sub-second propagation

DetectionChanges in IBM Db2 are captured at the source via change data capture — no polling loop against its API. Log-based CDC through IBM's replication tooling where licensed.

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

Lever IBM Db2 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 IBM Db2 as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • IBM Db2: No API rate limits; throughput is bounded by instance resources and workload management settings.
  • 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.
