amazon-web-services - 您请求的无服务器引擎模式目前在 5.7 (2.07.1) 中不可用

Question

尝试使用 MySQL 2.07.1 创建 RDS aurora 服务器并收到错误“您请求的引擎模式无服务器当前不可用。(服务:AmazonRDS；状态代码:400；错误代码:InvalidParameterValue；请求 ID:xxxx；代理:null)”

任何建议都会对我有很大帮助

这里是示例代码

要查看无服务器模式下可用的版本，请运行以下命令:

aws rds describe-db-engine-versions --engine aurora-mysql --filters Name=engine-mode,Values=serverless

如果你想了解根据引擎模式有哪些数据库版本可用，只需删除过滤器即可:

aws rds describe-db-engine-versions --engine aurora-mysql

通过这种方式，您将看到无服务器或配置模式下的可能性，以及每种模式支持的数据库版本。

特别是 SupportedEngineModes block ，通常如下所示:

"SupportedEngineModes": [
   "serverless"
]

或者

"SupportedEngineModes": [
   "provisioned"
]
