Designing Massively Scalable Storage

Table Storage

Provides Structured StorageMassively Scalable Tables

Billions of entities (rows) and TBs of data

Can 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 LINQ

REST – 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 scalability

RowKey – unique id within the partition

the only indexed property

Timestamp – for optimistic concurrency

255 properties for your data

Max size of 1MB

Table Schema

Define the schema as a .NET class

[DataServiceKey("PartitionKey", "RowKey")]public class User{

// ChannelNamepublic string PartitionKey { get; set; }// PostedDatepublic string RowKey { get; set; }

// User defined propertiespublic string Id { get; set; }public int Name { get; set; }

}

Azure

Windows Platform Integration

Reuse .NET skills

Fully compatible with ADO.NET data services

.NET client included in .NET 3.5 SP1

LINQ support

ASP.NET integration for website authoringSample data source control for data binding

ASP.NET dynamic data for instant front-ends

ASP.NET providers for membership, roles, etc.
