切换集群实例可用区 - UpdateAzByInstanceType
功能介绍
可用区(Availability Zone,AZ)指在同一区域(Region)下,电力、网络隔离的物理区域。同一地域内的可用区之间通过内网互通,但彼此在物理层面保持隔离,以降低单点故障风险。
多可用区部署是CSS服务提供的高可用性解决方案。通过在同一个地域内选择2个或3个不同的可用区部署集群,可有效防止数据丢失并降低服务中断风险。
该接口通过指定节点类型切换可用区。

调用方法
请参见如何调用API。
授权信息
账号具备所有API的调用权限,如果使用账号下的IAM用户调用当前API,该IAM用户需具备调用API所需的权限。
- 如果使用角色与策略授权,具体权限要求请参见权限和授权项。
- 如果使用身份策略授权,需具备如下身份策略权限。

请求参数
| 参数 | 是否必选 | 参数类型 | 描述 |
|---|---|---|---|
| source_az | 是 | String | 参数解释: 节点当前所在可用区。 约束限制: 不涉及 取值范围: 不涉及 默认取值: 不涉及 |
| target_az | 是 | String | 参数解释: 节点目标可用区。 约束限制: 不涉及 取值范围: 不涉及 默认取值: 不涉及 |
| migrate_type | 是 | String | 参数解释: 可用区迁移方式。 约束限制: 取值范围: 默认取值: 不涉及 |
| agency | 是 | String | 参数解释: 委托名称,重建节点时会重新绑定网卡,需要VPC的操作权限。选择IAM委托,授权当前账号访问和使用VPC的权限。 约束限制: 无法配置含特殊字符和中文字符的委托,允许使用的委托名称仅可包含a-zA-Z0-9-_字符。 取值范围: 不涉及 默认取值: 不涉及 |
| indices_backup_check | 否 | Boolean | 参数解释: 是否进行全量索引快照备份检测。建议选择进行全量索引快照备份检测,保证数据有备份,防止任务失败,数据丢失。 约束限制: 不涉及 取值范围: 默认取值: true |
