Microsoft Graphは作成/削除のために多くの不必要な通知を送信します

Question

効率を高めるために、システムをポーリングからwebhooksサブスクリプションとデルタクエリを使用するようにアップグレードしました。

しかし、ウェブフックの場合、私は不必要な/偽の通知をたくさん得ていることを知っています。

たとえば、ユーザがイベントをキャンセルした場合、通知は複数のupdateと表示され、そのあとにはdeleted通知が1秒間で送信されます。

これは、（作業キューが空であれば）通知に即座に反応できるのではなく、スロットル/デバウンスを追加しなければならないという状況を作り出すので、非常に面倒ですウェブフックからのより正確な読み取り。次のように

も更新を招く削除の例は：

は、同様に第二の画分中の同じイベントに対して複数の更新通知を送信します。秒以内に、いくつかのアップデートイベントが続くことができます作成​​され

通知は、Outlookのカレンダーの行動の結果です。特定の変更タイプのみを購読したり、サブスクリプションに$フィルタを使用することを検討することができます。

POST https://graph.microsoft.com/V1.0/subscriptions 

Header: 
Content-type = application/json 

Body: 
{ 
    "resource": "me/mailFolders('Inbox')/messages?$filter=IsRead%20eq%20false", 
    "notificationUrl": "https://mywebhook.azurewebsites.net/api/send/NotifyClient", 
    "changeType": "Created,Deleted ", 
    "expirationDateTime": "2017-06-30T18:23:45.935Z", 
    "clientState": "Message unread" 
}
