Why teams connect ClickHouse and Workday

Land the financial records from Workday in ClickHouse 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 Custom Reports (RaaS), Workers, Organizations, Positions from Workday into tables in ClickHouse in real time, and the connection works in both directions: values computed in ClickHouse can be written back to fields in Workday 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

  • Keep supervisory-organization hierarchies aligned with planning and workforce tools that model the same structure.
  • Sync worker records from Workday into IT and identity systems so hires, transfers, and terminations provision access automatically.
  • Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
  • Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.

Queryable history for audit and reconciliation

A continuously synced copy in ClickHouse 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 Workday arrive in ClickHouse as queryable tables, current within seconds instead of a day behind.

Revenue joined with everything else

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