AI打分理由: "正文主线是Oracle MySQL HeatWave独立数据库系统的蓝绿部署功能，用于低停机升级和基础设施变更，并非超节点、AI Rack或机架级AI基础设施。来源为Oracle官方发布说明，权威性高；固定知识库未发现该功能的明确历史记录，但知识库不完整且正文无发布日期，不能认定首次发布。新增事实仅为支持预先验证目标数据库并切换客户端连接，缺少机架拓扑、互连、功耗、散热等技术信息，也无客户、量产或规模部署信号。页面较短但事实可抽取并链接详细文档；因主题不相关且未命中任何高价值准入通道，判定非优质。"

You can now use blue/green deployments to perform low-downtime upgrades and infrastructure changes for standalone DB systems. A blue/green deployment prepares and validates a green (target) DB system before switching client connections from the blue (source) DB system to the target DB system.

For more information, see [Blue/Green Deployment](https://docs.oracle.com/iaas/mysql-database/doc/blue-green-deployments.html).
