28 Designing Massively Scalable Storage Table Storage Provides Structured Storage Massively Scalable Tables Billions of entities (rows) and TBs of data Can use thousands of servers as traffic grows Highly Available Can always access your data Durable Data is replicated several times Familiar ADO.NET Data Services API.NET classes and LINQ REST with any platform or language

29 Data Model Data stored in Tables A Table is a set of Entities (rows) An Entity is a set of Properties (columns) Entity has: PartitionKey enables scalability RowKey unique id within the partition the only indexed property Timestamp for optimistic concurrency 255 properties for your data Max size of 1MB

ChannelName public string PartitionKey { get; set; } // PostedDate public

30 Table Schema Define the schema as a.net class [DataServiceKey("PartitionKey", "RowKey")] public class User { // ChannelName public string PartitionKey { get; set; } // PostedDate public string RowKey { get; set; } } // User defined properties public string Id { get; set; } public int Name { get; set; }
