Why teams connect CockroachDB and Coupa

Work with Coupa's financial data straight from CockroachDB: read it with ordinary queries, write to it from your own code, and let Stacksync keep both sides consistent.

Engineers need finance data more often than finance systems make it easy to get: for internal tools, reporting services, or logic that reacts to invoices and payments. Working through the vendor API means rate limits, pagination, and glue code that has to be maintained forever.

Stacksync mirrors Accounts, Contracts, Expense Reports, Requisitions from Coupa into Tables, Views, Indexes, Sequences in CockroachDB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against CockroachDB, and rows your code writes or updates flow back into Coupa with validation, so the finance system stays the system of record.

Common use cases

  • 01 Provision and update Users in Coupa from an HRIS or identity provider as employees join, change roles, or leave.
  • 02 Mirror Purchase Orders and their status into an operational Postgres database for spend reporting and three-way match analytics.
  • 03 Consolidate data from several SaaS tools into one distributed SQL store that survives zone failures.
  • 04 Write application events from CockroachDB back to CRM fields to give go-to-market teams product context.

Common sync patterns

Internal tools without API plumbing

Build dashboards and back-office tools directly on CockroachDB; Stacksync handles the API calls, rate limits, and retries against Coupa.

Write back safely

Updates written to the synced tables in CockroachDB propagate into Coupa, so automations can create or correct finance records without custom integration code.

React to financial events

Changes in Coupa appear in CockroachDB as row changes, so you can trigger downstream logic with the database tooling you already use.

What you can sync between CockroachDB and Coupa

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 Coupa objects How this pairing syncs
Sequences ID generators that matter when writes originate from an external system. Contracts Supplier contract records with terms and dates; read out for reporting or created from a CLM system. Sequences is specific to CockroachDB and Contracts to Coupa — 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. Expense Reports Employee expense reports and their lines; exported to AP or ERP for reimbursement and GL posting. Changefeeds is specific to CockroachDB and Expense Reports to Coupa — each maps to any object or custom field on the other side.
Databases Logical containers a sync connects to, addressed like PostgreSQL databases. Requisitions Employee purchase requests with lines and approval chains; read out to warehouses, or created via the API from upstream intake tools. Databases is specific to CockroachDB and Requisitions to Coupa — 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. Purchase Orders PO headers and lines; synced two-way with ERPs so orders raised in Coupa flow to the ledger and status updates flow back on the /purchase_orders resource. Schemas is specific to CockroachDB and Purchase Orders to Coupa — each maps to any object or custom field on the other side.
Tables The core read/write target; rows sync bi-directionally with SaaS objects or other databases. Invoices Supplier/AP invoices with lines and approval status; polled out to accounting and ERP systems for the pay cycle, or created through the API. Tables is specific to CockroachDB and Invoices to Coupa — each maps to any object or custom field on the other side.
Views Read-only projections used as curated sync sources. Suppliers Supplier master records; kept aligned with an ERP vendor master and onboarding tools, synced two-way on the /suppliers resource. Views is specific to CockroachDB and Suppliers to Coupa — each maps to any object or custom field on the other side.

How changes propagate between CockroachDB and Coupa

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 Coupa 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 Coupa through its API, with automatic retries and rate-limit backoff.

Coupa CockroachDB Interval-based propagation

DetectionStacksync polls Coupa for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at and created-at filters (e.g.

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.
  • Coupa: Coupa does not publish explicit rate limits or expose X-RateLimit/Retry-After headers; integrations page 50 records at a time and back off on 429/503 responses.
