使用PowerShell在Azure China创建Data Warehouse

微软的Azure Data Warehouse是基于MPP架构的分布式系统：

Control Node负责管理系统和接受用户的请求，Compute Node负责计算。

目前在国内Azure Data Warehouse已经落地了。可以使用新的Portal页面进行管理，也可以使用PowerShell进行管理。

本文将介绍用PowerShell的管理方式。包括创建、Scale out、Suspend和Resume。

1 环境准备

登陆Azure China，并创建Resource Group

$mycred = Get-Credential -UserName admin@xxxx.partner.onmschina.cn -Message hello
Login-AzureRmAccount -EnvironmentName AzureChinaCloud -Credential $mycred
 
New-AzureRmResourceGroup -Name hwdweast -Location "China East"
 
ResourceGroupName : hwdweast
Location : chinaeast
ProvisioningState : Succeeded
Tags :
ResourceId : /subscriptions/xxxx-xxxx-xxxx/resourceGroups/hwdweast
 

2 创建Azure SQL Server

创建的SQL Server是V12版本

$sqlcred = Get-Credential -UserName hengwei -Message hello
New-AzureRmSqlServer -ServerName hwdwsv -SqlAdministratorCredentials $sqlcred -ResourceGroupName hwdweast -Location "China East" -ServerVersion 12.0 

ResourceGroupName : hwdweast
ServerName : hwdweast
Location : China East
SqlAdministratorLogin : hengwei
SqlAdministratorPassword :
ServerVersion : 12.0
Tags : 

3 给新创建的Database server配置Firewall规则，本例子中因为是测试，添加了所有可用的地址段

new-AzureRmSqlServerFirewallRule -FirewallRuleName all -StartIpAddress 1.1.1.1 -EndIpAddress 223.255.255.254 -ServerName hwdweast -ResourceGroupName hwdweast
 
ResourceGroupName : hwdweast
ServerName : hwdweast
StartIpAddress : 1.1.1.1
EndIpAddress : 223.255.255.254
FirewallRuleName : all
 

4 创建Data WareHouse

New-AzureRmSqlDatabase -DatabaseName hwdwdbeast -RequestedServiceObjectiveName "DW100" -ServerName hwdwsv -ResourceGroupName hwdweast -Edition DataWarehouse -CollationName "SQL_Latin1_General_CP1_CI_AS" -MaxSizeBytes 10995116277760

ResourceGroupName : hwdweast
ServerName : hwdweast
DatabaseName : hwdwdbeast
Location : China East
DatabaseId : 3e5f4387-099d-4a7d-858d-0d663381663a
Edition : DataWarehouse
CollationName : SQL_Latin1_General_CP1_CI_AS
CatalogCollation :
MaxSizeBytes : 1099511627776
Status : Online
CreationDate : 2016/10/5 13:46:19
CurrentServiceObjectiveId : 4e63cb0e-91b9-46fd-b05c-51fdd2367618
CurrentServiceObjectiveName : DW100
RequestedServiceObjectiveId : 4e63cb0e-91b9-46fd-b05c-51fdd2367618
RequestedServiceObjectiveName :
ElasticPoolName :
EarliestRestoreDate : 0001/1/1 0:00:00
Tags :
ResourceId : /subscriptions/xxxx-xxxx-xxxx/resourceGroups/hwdweast/providers/Microsoft.Sql/servers/hwdw
east/databases/hwdwdbeast
CreateMode :
 

其中，

-Edition DataWarehouse 表明这个是Data Warehouse

-RequestedServiceObjectiveName "DW100" 指定Data Warehouse的大小，DW100表示有1个计算节点

-CollationName "SQL_Latin1_General_CP1_CI_AS" 指定字符集

-MaxSizeBytes 10995116277760 指定最大容量

几分钟的时间，一个Data Warehouse就创建好了。

4 更改Data Warehouse大小

set-azurermsqldatabase -DatabaseName hwdwdbeast -RequestedServiceObjectiveName "DW200" -ServerName hwdwsv -ResourceGroupName hwdweast
 
ResourceGroupName : hwdweast
ServerName : hwdweast
DatabaseName : hwdwdbeast
Location : China East
DatabaseId : 3e5f4387-099d-4a7d-858d-0d663381663a
Edition : DataWarehouse
CollationName : SQL_Latin1_General_CP1_CI_AS
CatalogCollation :
MaxSizeBytes : 1099511627776
Status : Online
CreationDate : 2016/10/5 13:46:19
CurrentServiceObjectiveId : 99e78a92-d724-4e1b-857b-2be661f3d153
CurrentServiceObjectiveName : DW200
RequestedServiceObjectiveId : 99e78a92-d724-4e1b-857b-2be661f3d153
RequestedServiceObjectiveName :
ElasticPoolName :
EarliestRestoreDate : 0001/1/1 0:00:00
Tags :
ResourceId : /subscriptions/xxxx-xxxx-xxxx/resourceGroups/hwdweast/providers/Microsoft.Sql/servers/hwdw
east/databases/hwdwdbeast
CreateMode :
 

5 暂停某个Data Warehouse的服务

Suspend-AzureRmSqlDatabase -DatabaseName hwdwdbeast -ServerName hwdweast -ResourceGroupName hwdweast
 
ResourceGroupName : hwdweast
ServerName : hwdweast
DatabaseName : hwdwdbeast
Location : China East
DatabaseId : 3e5f4387-099d-4a7d-858d-0d663381663a
Edition : DataWarehouse
CollationName : SQL_Latin1_General_CP1_CI_AS
CatalogCollation :
MaxSizeBytes : 1099511627776
Status : Paused
CreationDate : 2016/10/5 13:46:19
CurrentServiceObjectiveId : 4e63cb0e-91b9-46fd-b05c-51fdd2367618
CurrentServiceObjectiveName : DW100
RequestedServiceObjectiveId : 4e63cb0e-91b9-46fd-b05c-51fdd2367618
RequestedServiceObjectiveName :
ElasticPoolName :
EarliestRestoreDate : 0001/1/1 0:00:00
Tags :
ResourceId : /subscriptions/xxxx-xxxx-xxxx/resourceGroups/hwdweast/providers/Microsoft.Sql/servers/hwdw
east/databases/hwdwdbeast
CreateMode : 

此时，数据还保留在Data Warehouse中，但计算单元已经停止计费了。

这种模式特别适合需要月末、季度末、年末进行报表统计的场景。

6 恢复某个Data Warehouse的服务

Resume-AzureRmSqlDatabase -DatabaseName hwdwdbeast -ServerName hwdweast -ResourceGroupName hwdweast
 
ResourceGroupName : hwdweast
ServerName : hwdweast
DatabaseName : hwdwdbeast
Location : China East
DatabaseId : 3e5f4387-099d-4a7d-858d-0d663381663a
Edition : DataWarehouse
CollationName : SQL_Latin1_General_CP1_CI_AS
CatalogCollation :
MaxSizeBytes : 1099511627776
Status : Online
CreationDate : 2016/10/5 13:46:19
CurrentServiceObjectiveId : 4e63cb0e-91b9-46fd-b05c-51fdd2367618
CurrentServiceObjectiveName : DW100
RequestedServiceObjectiveId : 4e63cb0e-91b9-46fd-b05c-51fdd2367618
RequestedServiceObjectiveName :
ElasticPoolName :
EarliestRestoreDate : 0001/1/1 0:00:00
Tags :
ResourceId : /subscriptions/xxxx-xxxx-xxxx/resourceGroups/hwdweast/providers/Microsoft.Sql/servers/hwdw
east/databases/hwdwdbeast
CreateMode :
 

目前Data Warehouse还只能通过PowerShell的方式进行创建，将来China 的Azure也会和Global的Azure一样，通过图形化界面完成上面所有的操作。
