AppEngine RemoteAPI SocketTimeoutException

我正在使用RemoteAPI從GAE Datastore中一次獲取300個實體。AppEngine RemoteAPI SocketTimeoutException

我做線沿線的東西：

while(!(emails = getEmails()).isEmpty()) { 

    Filter filter = new FilterPredicate("email", FilterOperator.IN, emails) 
    Query query = new Query("MyEntity").setFilter(filter); 
    QueryResultIterable<Entity> result = ds.prepare(query).asQueryResultIterable(); 

    for (Entity entity : result) { 
    System.out.println(entity.getProperty("name")); 
    } 
}

我處理類似50K電子郵件。當我第一次運行這個代碼時，它可能是3/4，然後拋出了下面的異常。現在它在單循環迭代運行後拋出它。

我找不出什麼問題，但代碼似乎是在拋出異常之前評估for（）條件。

這可能是一個配額問題？配額詳細信息屏幕沒有顯示任何問題，我在文檔中找不到任何相關信息。

我試過今天運行完全相同的代碼，它只是工作。我已經多次執行它（試圖弄清楚它是否與配額有關的問題），但是我無法**重現該問題。我仍然不知道問題是什麼。 –

我得到這些很少，但他們很煩惱。你有沒有得到這個決議？如果可能的話，我寧願趕上這些，然後重試。 –

我什麼都沒改變，第二天它只是工作。所有配額都低於限額。不知道是什麼。 :( –
