Key Takeaways
  • Most teams run three separate databases for transactions, analytics, and AI — each adding sync lag, consistency gaps, and operational overhead. OceanBase 4.4.2 LTS collapses all three into one engine.
  • Key upgrades: ~60% faster DDL, 14x follower-read improvement, full materialized-view support, native vector + full-text hybrid search, transparent column encryption, and heterogeneous zone deployment for smoother failure recovery.
  • If you're building RAG, semantic search, or real-time analytics on operational data, 4.4.2 LTS lets you do it without copying data to a separate system.
