app_identity_service.GetAccessToken（）需要比可用配額更多的配額

Question

我正在使用應用引擎和大型查詢作爲我網站的後端。無論何時用戶點擊一下，我都會將它們記錄到bigquery中，以便在當天晚些時候進行分析。我每天接近75,000次點擊。直到上週，它一切正常。這是我使用的代碼。

body = {"rows":[bodyFields]} 

    credentials = appengine.AppAssertionCredentials(scope=BIGQUERY_SCOPE) 
    http = credentials.authorize(httplib2.Http()) 
    bigquery = discovery.build('bigquery', 'v2', http=http) 

    response = bigquery.tabledata().insertAll(
     projectId=PROJECT_ID, 
     datasetId=BIGQUERY_DATASETID, 
     tableId=BIGQUERY_TABLEID, 
     body=body).execute() 

現在突然間我超過了配額例外。我的應用程序是付費應用程序引擎實例。下面是我的例外

我的流量已經沒有時間處理程序被擊中也多數量上升的堆棧跟蹤幾乎是一樣的近2個月的數據。那麼爲什麼我得到這個錯誤。

Answer 1

爲了確定您遇到配額錯誤的原因，您需要共享有關您的使用情況的更多詳細信息。配額應每24小時重置一次。你知道這個錯誤出現需要多長時間，並且你已經成功服務了多少流量？

你提到你「在今天晚些時候做分析」，這表明你可能使用的是TaskQueue API或Deferred Tasks。這些任務可能因其他原因而失敗，並且可能會很快耗盡您的配額。如果您使用的是TaskQueues，則可以嘗試調整queue configuration and retry options。

另一種可能可以節省配額的方式是將正在構建的bigquery發現服務保存爲類似於Memcache API的內容，以便它可以重複用於對BigQuery服務的多個請求。
