Where each one falls short

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

OpenSearch

  • Diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
  • Operationally heavy in the way Elasticsearch is: cluster sizing, shard strategy and JVM tuning are ongoing work
  • Smaller ecosystem of third-party tooling than Elasticsearch, which most integrations still target first
  • Overkill for plain application search, where a dedicated search engine is far simpler

ThoughtSpot

  • Limited chart customization options; font, color, and size customizations for visualizations are restricted
  • Data modeling setup is complex and requires specialized expertise
  • High implementation costs restrict adoption for smaller organizations
  • Requires quality data and user training to fully realize benefits
