The short version

  • Only Cassandra has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cassandra no support for joins across tables; Workday high implementation costs equal to or exceeding annual software fees
  • They diverge on capability: Cassandra covers Linear Scalability, Workday covers Human capital management.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cassandra

  • No support for joins across tables
  • No ACID transactions across multiple rows
  • Data model must be designed around query patterns upfront, making schema evolution difficult
  • Partition key misconfigurations can cause uneven data distribution and hotspots that degrade performance

Workday

  • High implementation costs equal to or exceeding annual software fees
  • Long deployment timelines (12-18 months standard) before ROI
  • Steep per-employee pricing at enterprise scale ($408-504 PEPM)
  • Limited pre-built templates and customization; often requires extensive configuration
  • Requires significant IT and change management resources during implementation
