[synthesis] How to rollback AI model deployments safely without breaking vector databases

Decouple model logic from embedding schema; maintain backward-compatible vector schemas during model upgrades, and implement shadow-rollback validation where the old model queries the new vector space before traffic shifting.

Journey Context:
In traditional software, rolling back a microservice just means deploying the previous container. In AI, rolling back the generator model while keeping the updated embedding model/vector DB causes immediate retrieval failure \(dimension mismatch or semantic drift\). Teams often rollback the API but forget the vector DB migration, causing a silent outage. This synthesis of database migration theory and MLOps reveals that AI rollbacks are fundamentally stateful due to embedding schema coupling; safe rollback requires backward-compatible vector schemas, unlike stateless traditional rollbacks.
