When should I avoid vearch?

If your project does not require cloud-native deployment or Kubernetes integration, Vearch might offer more features than necessary. If your application does not benefit from retrieval-augmented generation, Vearch's specialized features might not be fully utilized. For scenarios where the application does not involve AI-native operations, Vearch's specialized design for AI-native applications might not be the best fit.
