Pros
  • Auto-syncs indexes from Delta tables — no bespoke embedding pipeline
  • Hybrid semantic + BM25 + reranking in a single API
  • Unity Catalog governance and ACLs extend to the index
  • Serverless, scales to billions of vectors and high QPS
  • Focused on retrieval (not general agent stuff)
  • Many ingestion connectors
  • Strong production patterns
  • LlamaCloud for managed ingestion
Cons
  • Only economical if you are already on Databricks
  • Enterprise pricing is opaque without a sales conversation
  • Not open source; lock-in to the Databricks platform
  • Overkill for small RAG prototypes
  • API surface is large
  • Documentation can be hard to navigate
