UnverifiedA vector index is essentially a copy of the documents, must be kept in sync with the data source, requires rebuilding the entire index when the embedding model is changed, and must enforce the same access permission controls as the original system.90% similarUnverifiedAfter permission changes, an incremental index rebuild needs to be triggered, otherwise the old permissions will persist along with the vectors.75% similarUnverified数据库需要持久化存储、数据一致性、主从复制、自动备份和故障切换，这些需求与容器的短暂性本质相冲突73% similarUnverifiedThe vector index itself is not the source of truth but a derived view; the original records must be kept in auditable storage so they can be rebuilt if the index is corrupted or migrated.73% similarUnverifiedThe prerequisite for rollback is that operations are idempotent or transactionally guaranteed; database changes should prioritize migration scripts over direct SQL, and file changes should be included in version control.70% similar
