Designing Massively Scalable StorageTable StorageProvides Structured Storage

Massively Scalable TablesBillions of entities (rows) and TBs of dataCan use thousands of servers as traffic grows

Highly AvailableCan always access your data

DurableData is replicated several times

Familiar ADO.NET Data Services API.NET classes and LINQREST – with any platform or language

Data Model

Data stored in TablesA Table is a set of Entities (rows)An Entity is a set of Properties (columns)

Entity has:PartitionKey – enables scalabilityRowKey – unique id within the partition

the only indexed property Timestamp – for optimistic concurrency255 properties for your dataMax size of 1MB

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; }}
