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

Qlik Sense

  • Expensive pricing structure, particularly for enterprise users and large data volumes
  • Performance degradation when working with very large datasets
  • Limited field capacity and strict 10 GB data limit on Starter plan ($300/month)
  • Weak date handling in set analysis compared to other BI tools
  • Poor API usability, particularly for Python scripts and integration workflows
