获取异常 - "属性值大于表服务允许的值",天蓝色存储表中行的最大大小是多少

Question

尝试在azure表存储中插入记录时,获取异常"属性值大于表服务允许的值".

Follwing是我的表结构,字符串PartitionKey,String RowKey,字符串Id,字符串站点,字符串名称,byte []内容,
public DateTime createdtime

我试图在内容字段中保存83755字节数组(82KB),其他字段最多35个字符.

谁能告诉我天蓝色存储表的最大行数是多少？

以下是我提到的网址..其中提到的行最多可以有1MB.但我的不超过100 KB.

谢谢,

Answer 1

是的,每行最多可以有1MB.但是,每个字节数组属性或字符串属性限制为64K.有关每种数据类型的详细信息,请参阅此MSDN参考.

Answer 2

我建议查看Lokad.Cloud for Azure框架(开源).有一个经过生产测试的代码,用于将大型实体序列化到表存储中,限制为960KB(属性拆分和管理由框架处理)

以下是FatEntities wiki的示例用法

// TODO: change your connection string here
var providers = Standalone.CreateProviders(
   "DefaultEndpointsProtocol=https;AccountName=;AccountKey=");

// 'books' is the name of the table
var books = new CloudTable<Book>(providers.TableStorage, "books");

var potterBook = new Book 
   { Author = "J. K. Rowling", Title = "Harry Potter" };

var poemsBook = new Book 
   { Author = "John Keats", Title = "Complete Poems" };

// inserting (or updating record in Table Storage)
books.Upsert(new[]
    {
        new CloudEntity<Book> {
            PartitionKey = "UK", RowRey = "potter", Value = potterBook},
        new CloudEntity<Book> {
            PartitionKey = "UK", RowRey = "poems", Value = poemsBook}
    });

// reading from table
foreach(var entity in books.Get())
{
    Console.WriteLine("{0} by {1} in partition '{2}' and rowkey '{3}'",
        entity.Value.Title, entity.Value.Author, 
        entity.PartitionKey, entity.RowRey);
}

Console.WriteLine("Press enter to exit.");
Console.ReadLine();
