Why teams connect Greenplum and Navan

Land the financial records from Navan in Greenplum continuously, and write results back, without building or maintaining a pipeline.

Finance data belongs in the warehouse: revenue, invoices, payments, and customers joined with everything else the business measures. Getting it there usually means an extraction pipeline that breaks quietly and delivers yesterday's numbers.

Stacksync syncs Receipts, Repayments, Fees, and Adjustments, Users, Card Transactions from Navan into tables in Greenplum in real time, and the connection works in both directions: values computed in Greenplum can be written back to fields in Navan where you want them operational. Schema changes are handled, API limits are managed, and the sync is something you configure rather than code you maintain.

Common use cases

  • 01 Pull Bookings by date range into a database to reconcile travel reservations against Card Transactions and monitor travel-policy spend.
  • 02 Sync Users and department mappings from an HRIS into reporting tables so every transaction is attributed to a cost center and manager.
  • 03 Consolidate data from multiple source systems into partitioned Greenplum fact tables.
  • 04 Load operational data from CRMs, ERPs, and production databases into Greenplum for MPP analytics.

Common sync patterns

Revenue joined with everything else

Analysts combine Navan's financial records with product, marketing, or operational data already in Greenplum for reporting the finance system cannot do alone.

Write-back of computed fields

Scores or segments computed in Greenplum, like payment-risk flags or customer tiers, sync back onto records in Navan where the finance team can act on them.

Queryable history for audit and reconciliation

A continuously synced copy in Greenplum gives you a durable, queryable record of financial data for month-end and audit questions.

What you can sync between Greenplum and Navan

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.

Greenplum objects Navan objects How this pairing syncs
Databases Top-level containers that scope a sync connection. Receipts Receipt images tied to each transaction; fetched read-only through presigned URLs for archival in a warehouse or document store. Databases is specific to Greenplum and Receipts to Navan — each maps to any object or custom field on the other side.
Schemas Namespace tables and control which objects a sync can see. Repayments, Fees, and Adjustments Money-movement records including repayments, FX and platform fees, and credit or debit memos; read-only for reconciliation ledgers. Schemas is specific to Greenplum and Repayments, Fees, and Adjustments to Navan — each maps to any object or custom field on the other side.
Tables Heap or append-optimized tables mapped directly to sync targets. Users Employee and cardholder records referenced by every transaction; usually provisioned from an HRIS and used to map spend to people and departments. Tables is specific to Greenplum and Users to Navan — each maps to any object or custom field on the other side.
Partitions Large tables are commonly partitioned by date, which shapes incremental reads. Card Transactions Navan physical and virtual card spend; read via GET, then GL codes, cost centers, and ERP sync status are written back per transaction through the transaction update endpoint. Partitions is specific to Greenplum and Card Transactions to Navan — each maps to any object or custom field on the other side.
Views Read-only projections used to shape data before syncing it out. Connect Transactions External and personal card feed matched into Navan; retrieved read-only and coded with custom-field values through the transaction update endpoint. Views is specific to Greenplum and Connect Transactions to Navan — each maps to any object or custom field on the other side.
External tables Reference external files for bulk load paths alongside row-level syncs. Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. External tables is specific to Greenplum and Manual Transactions to Navan — each maps to any object or custom field on the other side.

How changes propagate between Greenplum and Navan

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.

Greenplum Navan Interval-based propagation

DetectionStacksync polls Greenplum for changes on an incremental schedule, reading only records changed since the previous pass. Polling with timestamp or key-based cursors.

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

Navan Greenplum Sub-second propagation

DetectionNavan notifies Stacksync of record changes through webhook events. Navan's Expense API supports webhooks for transaction and expense events.

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

Rate-limit considerations

  • Greenplum: Bounded by cluster resources and concurrency settings rather than an API quota.
  • Navan: Requests are throttled with HTTP 429 and Navan recommends retrying with exponential backoff; the Expense/Public API must first be enabled per account by Navan.
