Why teams connect Apache Cassandra and Workday

Work with Workday's financial data straight from Apache Cassandra: 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 Workers, Organizations, Positions, Compensation from Workday into Partitions and Rows, Materialized Views, Secondary Indexes, User-Defined Types in Apache Cassandra and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Apache Cassandra, and rows your code writes or updates flow back into Workday with validation, so the finance system stays the system of record.

Common use cases

  • Sync worker records from Workday into IT and identity systems so hires, transfers, and terminations provision access automatically.
  • Replicate worker, organization, and compensation data into a secured database for people analytics without giving analysts tenant access.
  • Write attributes computed elsewhere (scores, preferences) back into Cassandra tables serving low-latency reads.
  • Feed Cassandra change streams into search indexes or caches that must track the source of truth.

Internal tools without API plumbing

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

Write back safely

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

React to financial events

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

What you can sync between Apache Cassandra and Workday

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 Cassandra objects Workday objects
Collections List, set, and map columns handled with type-aware field mapping. Compensation Pay components read into payroll, planning, and equity systems under strict access control.
Counters Increment-only counter columns, usually read-only in syncs. Time Off and Absence Balances and requests synced with scheduling and workforce tools.
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Payroll Results Completed pay data exported to finance and benefits systems.
Tables Wide-column tables addressed by partition key, the unit of row-level sync. Suppliers Workday Financials vendor records aligned with procurement tools.
Partitions and Rows Records located by partition and clustering keys during reads and upserts. Customers and Invoices Financials receivables objects synced for billing visibility where Workday Financials is used.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Journal Entries Accounting entries imported from external subledgers into Workday Financials.

How the Apache Cassandra and Workday connectors work

Apache Cassandra

Integration surface
CQL over the Cassandra native binary protocol
Authentication
Database credentials (password authenticator); TLS and role-based grants where configured
Change detection
Commit-log based CDC on tables with CDC enabled, or polling using writetime metadata and timestamp columns
Capabilities

Rate limits
No API quotas; throughput is governed by cluster capacity and consistency-level choices

Workday

Integration surface
SOAP Workday Web Services (WWS), a REST API, and Reports-as-a-Service (RaaS) endpoints for custom reports
Authentication
OAuth 2.0 for the REST API; integration system users with WS-Security or certificate-based auth for SOAP
Change detection
Polling, including transaction-log criteria on SOAP operations to fetch objects changed since a given moment; no general webhook surface
