AI Agents Need More Than Storage. OceanBase Built It Into the Engine

Key Takeaways
  • AI agents interact with databases hundreds of times per decision cycle — hybrid search, memory retrieval, and context updates need to happen in milliseconds, not across a fragile chain of external API calls.
  • The two mainstream approaches — bolted-on vector plugins and standalone vector databases — both break in production: one can't co-optimize across search types; the other demands a multi-hop glue architecture that collapses under load.
  • OceanBase 4.4.2 LTS embeds vector search, full-text search, and AI inference (AI_EMBED, AI_COMPLETE, AI_RERANK) inside the SQL engine, collapsing the agent's six-hop data pipeline into a single query backed by battle-tested ACID transactions.
