Why teams connect Apache Impala and Navan

Land the financial records from Navan in Apache Impala 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 Connect Transactions, Manual Transactions, Bookings, Custom Fields from Navan into tables in Apache Impala in real time, and the connection works in both directions: values computed in Apache Impala 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 Sync Card Transactions and Manual Transactions into Postgres or a warehouse so finance analyzes corporate spend in SQL without manual CSV exports.
  • 02 Push coded expense transactions into an accounting system, then set their ERP sync status in Navan so the same records are not exported twice.
  • 03 Read new partitions incrementally from Parquet tables and land them in a cloud warehouse during migration.
  • 04 Publish Impala query results (aggregates, KPIs) to CRMs or spreadsheets on a schedule.

Common sync patterns

Write-back of computed fields

Scores or segments computed in Apache Impala, 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 Apache Impala gives you a durable, queryable record of financial data for month-end and audit questions.

Finance analytics without ETL

Invoices, payments, and customer records from Navan arrive in Apache Impala as queryable tables, current within seconds instead of a day behind.

What you can sync between Apache Impala 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.

Apache Impala objects Navan objects How this pairing syncs
Users and Roles Principals (often via Ranger/Sentry) used to grant scoped read access. Users Employee and cardholder records referenced by every transaction; usually provisioned from an HRIS and used to map spend to people and departments. Users and Roles is specific to Apache Impala and Users to Navan — each maps to any object or custom field on the other side.
Databases Namespaces shared with the Hive Metastore that scope tables. 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. Databases is specific to Apache Impala and Card Transactions to Navan — each maps to any object or custom field on the other side.
Tables HDFS or object-storage backed tables (commonly Parquet) read at interactive speed. Connect Transactions External and personal card feed matched into Navan; retrieved read-only and coded with custom-field values through the transaction update endpoint. Tables is specific to Apache Impala and Connect Transactions to Navan — each maps to any object or custom field on the other side.
Partitions Partition values used to limit scans and drive incremental reads. Manual Transactions Out-of-pocket reimbursements and payroll submissions; synced for approval and reimbursement, then GL-coded back into Navan. Partitions is specific to Apache Impala and Manual Transactions to Navan — each maps to any object or custom field on the other side.
Views Logical views readable as modeled sources. Bookings Flight, hotel, rail, and car reservations from the Booking API; pulled read-only by createdFrom/createdTo date range for trip and travel-spend reporting. Views is specific to Apache Impala and Bookings to Navan — each maps to any object or custom field on the other side.
Kudu Tables Kudu-backed tables that support row-level insert, update, upsert, and delete. Custom Fields Company metadata such as cost centers and project codes; discovered via GET and their option lists created or updated via async POST. Kudu Tables is specific to Apache Impala and Custom Fields to Navan — each maps to any object or custom field on the other side.

How changes propagate between Apache Impala 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.

Apache Impala Navan Interval-based propagation

DetectionStacksync polls Apache Impala for changes on an incremental schedule, reading only records changed since the previous pass. Polling on partition or timestamp columns.

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

Navan Apache Impala 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 Apache Impala as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Apache Impala: No API quotas; concurrency is bounded by cluster resources and admission control settings.
  • 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.

How the Apache Impala and Navan connectors work

Apache Impala

Integration surface
SQL over JDBC/ODBC (HiveServer2-compatible protocol)
Authentication
Deployment-dependent: Kerberos, LDAP, or username/password
Change detection
Polling on partition or timestamp columns; no change log exposed for external consumers
Capabilities

Rate limits
No API quotas; concurrency is bounded by cluster resources and admission control settings

Navan

Integration surface
REST (Expense API and Booking API)
Authentication
OAuth 2.0 client-credentials flow; an admin creates a client_id and client_secret under Settings > Integrations and exchanges them at Navan's OAuth token endpoint for a short-lived bearer token that is refreshed on expiry (separate US and EU regional hosts)
Change detection
Navan's Expense API supports webhooks for transaction and expense events; sync engines also poll GET endpoints with date-range and updatedAt filters (createdFrom/createdTo for bookings) to backfill history and reconcile. There is no database-level CDC.
Capabilities

Rate limits
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.
