Pros
  • End-to-end RAG: ingest, process, vectorize, and serve from one platform
  • Cloud, private-server, and on-prem deployment options for compliance buyers
  • SOC 2 Type I and Type II compliant with encryption in transit and at rest
  • No-code framework lowers the lift for teams without ML platform engineers
  • True hybrid retrieval — BM25 + dense + sparse (ELSER) in one query with reranking
  • Filters, aggregations, geo, and time-series in the same index, so one cluster serves search + analytics + RAG
  • `semantic_text` field handles chunking and embedding calls automatically at ingest
  • Better Binary Quantization slashes vector RAM footprint dramatically for billion-scale corpora
  • Broad embedding-provider and framework support (OpenAI, Cohere, Bedrock, Vertex, LangChain, LlamaIndex)
  • Enterprise-grade RBAC, field/document-level security, and audit — rare among vector DBs
  • Open-source core with self-managed, cloud, and serverless deployment paths
Cons
  • No public pricing; enterprise sales motion required
  • Marketing site is thin on technical stack details (models, vector store)
  • No visible free tier or self-serve trial
  • Likely overkill for solo developers or simple chatbot use cases
  • Steeper learning curve and operational overhead than purpose-built vector DBs like Pinecone or Qdrant
  • JVM cluster tuning (heap, shards, HNSW parameters) is non-trivial at scale
  • Cloud Hosted pricing is opaque compared to per-vector pricing of newer competitors
  • License change (Elastic License v2 / SSPL) blocks some managed-service resellers
  • Latency-sensitive pure-vector workloads can be beaten by specialised ANN-only engines
