对于Azure Cosmos DB，是否可以从单区域写入改为多区域写入？
[英]For Azure Cosmos DB, is it possible to change from single region write to multi region write?
问题描述
As Cosmos DB cost extra for multi-region write, is it possible to start with single region write and upgrade to multi-region write at a later stage or will that require a database migration?
由于 Cosmos DB 多区域写入需要额外费用，是否可以从单区域写入开始，然后升级到多区域写入，或者是否需要迁移数据库？
From the pricing information it looks like the multi-region write pricing kicks in even if you don't have any geo redundancy configured.从定价信息来看，即使您没有配置任何地理冗余，多区域写入定价似乎也会生效。 So it looks like you either have to go with a high cost from the start, or choose to pay the price through a migration at a later stage.所以看起来你要么从一开始就付出高昂的代价，要么选择在后期通过迁移来付出代价。 Is this a correct observation?这是一个正确的观察吗？

Multi-region write functionality can be enable after a single region account has been created.创建single region帐户后，可以启用多区域写入功能。 This can be done via the Azure Portal or via Powershell: Set up Azure Cosmos DB global distribution using the SQL API这可以通过 Azure 门户或 Powershell 完成： 使用 SQL API 设置 Azure Cosmos DB 全球分发
This applies to the SQL(Core) API.这适用于 SQL(Core) API。
Powershell example: Replicate an Azure Cosmos DB database account in multiple regions and configure failover priorities using PowerShell Powershell 示例： 在多个区域复制 Azure Cosmos DB 数据库帐户并使用 PowerShell 配置故障转移优先级
