  • They diverge on capability: Cassandra covers Linear Scalability, Zoom covers HD video & audio.

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

Zoom

  • Cost creep from add-ons increases pricing from $14/user to $25+/user when including Phone and advanced features
  • Feature set is overwhelming with complex navigation and too many options
  • Limited analytics and coaching features compared to dedicated contact center platforms
  • Call recording and admin oversight lack strict governance needed for regulated industries
