#はじめに
Automationでやるのは意外と面倒そうということでAzure Data Factoryから実行する方法をまとめます

#参考
参考コード
https://github.com/furmangg/automating-azure-sql-dw

公式
Azure SQL Data Warehouse の REST API

#手順概要

Azure Data FactoryでPipelineを作成
SQL Data WarehouseのあるSQL Serverの各種情報をPipelineに設定
SQL ServerのロールをData Factoryに割り当て

##権限について
Data Warehouseの再開、停止、性能変更は下記のような操作で実行されるため、最小の権限ロールを作成する場合は以下を実行できるロールを作成します。

再開　"action": "Microsoft.Sql/servers/databases/resume/action"
停止　"action": "Microsoft.Sql/servers/databases/pause/action"
性能変更 "action": "Microsoft.Sql/servers/databases/write"
性能変更はdatabaseリソース自体の書き換えになってますね

組み込みロールにはないので、以下の許可を持っているSQL DB Contributorあたりを振っておけばOK.(もちろん共同作成者でもOK)
SQL DB Contributor

Microsoft.Sql/servers/databases/*
#手順
##Azure Data FactoryでPipelineを作成
###再開用Pipeline
名前を「ResumeAzureSQLDW」にして空のPipelineを作ります

パイプラインのDWUパラメータを変更することでアップ時の性能を制御しています。

Trigger nowかdebugで動作確認してみましょう

#まとめ
これを利用すればData Factoryでバッチジョブ実行をする際にフロー中で再開→性能アップ→処理→性能ダウン→休止が可能になります。

#補足
UntilSqlDwOnlineなどのチェック部分が毎秒チェックして回数＝課金がかさむかもしれないのである程度waitを入れてもいいかもしれません
あとDWの情報は親のパイプラインに持たせて共通のパラメータにしたりね。。
