Pros
  • Genuinely live indexing - documents update without rebuild jobs
  • Self-hosted under BSL 1.1, no data leaves your infra
  • Rich connector library (Kafka, S3, SharePoint, Postgres, Delta Lake)
  • Same pipeline handles batch and streaming
  • 20+ production-ready templates including multimodal and adaptive RAG
  • Native vector search with HNSW sits inside a full SQL database, so embeddings can be filtered and joined against relational data in one query
  • Unified HTAP + vector engine removes an entire class of ETL between OLTP, warehouse, and vector store for RAG apps
  • Open-source core (Apache 2.0) with credible self-managed deployment option, avoiding hard lock-in to the managed cloud
  • MySQL wire-protocol compatibility means most ORMs, BI tools, and existing app code work with minimal changes
  • Horizontal scalability with strong ACID guarantees, workload isolation, and multi-cloud dedicated clusters
  • Serverless Starter tier is genuinely free to explore and integrates with LangChain, LlamaIndex, and MCP out of the box
Cons
  • Steeper learning curve than prompt-chain frameworks
  • BSL is not OSI-approved - commercial restrictions apply at scale
  • Smaller community than LangChain/LlamaIndex
  • Pricing for Scale/Enterprise tiers not transparent
  • Not an AI tool per se — it is infrastructure; teams still need to build the agent, retrieval, and orchestration layers on top
  • Vector features are newer than dedicated vector databases like Pinecone, Weaviate, or Milvus and lack some advanced hybrid-search tuning
  • Operational surface area is large: TiDB, TiKV, TiFlash, PD components are non-trivial to run well when self-managed
  • Dedicated and Premium tiers get expensive quickly ($1.3k-$1.8k/mo entry point) compared with a small Postgres + pgvector setup
  • Pricing on the Essential/Premium tiers uses Request Units and preview status, which makes cost forecasting harder than fixed-node plans
