AI doesn't hide shallow thinking. It accelerates it.
Two types of engineers are emerging in 2026 — those thinking with AI, and those outsourcing thinking to it.
The divide is already here.
Without your critical thinking, would AI still answer you right?

Oracle 23ai: vector search is not a bolt-on.

VECTOR type, HNSW/IVF indexes, Select AI — all native SQL.
No external round trip needed.

@connor_mc_d Meanwhile, why I concluded this:

1. Vector datatype = data stays in Oracle
2. ONNX model = embedding generation internal (vs external conversion)
3. 23ai docs: "Brings AI algorithms to where data lives, not moving data to AI"

May have misinterpreted.

Stop. Before you shard your database...

OpenAI proved you can serve 800M users without sharding.

I analyzed their PostgreSQL architecture and found 5 myths
every DBA should know.

@connor_mc_d Merry Christmas Connor! Thanks for all the excellent Oracle content throughout the year. Enjoy the break! 🎄

[Sanjeeva Kumar @kumarsanjeeva]

🔥 Hot take: Your startup doesn't need a vector database.
PostgreSQL + pgvector handles 90% of AI workloads at 60-80% lower cost. AWS, Google Cloud, Azure ALL bet on PostgreSQL for AI. Why?

@connor_mc_d Thank you for this Clarification. I understand your point now 🙂

💡 DBA Tip:

Always set undo_retention to 3600+ for OLTP systems

Why? Reduces ORA-01555 snapshot errors during long queries

@Nagarro Excellent ! Strengthening our retail & CPG capabilities while expanding our US presence. Welcome to the CHTS team! 💪

[Sanjeeva Kumar @kumarsanjeeva]

@RichNiemiec Spot on! Writing about PostgreSQL vector capabilities currently, however Oracle's integrated approach with 26ai looks compelling.
The native vector DB + agent architecture could be game-changing for enterprises already invested in Oracle ecosystem.
Worth exploring both paths.
