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
30. Table Schema
Define the schema as a .NET class
[DataServiceKey(quot;PartitionKeyquot;, quot;RowKeyquot;)]
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; }
}
32. 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 authoring
Sample data source control for data binding
ASP.NET dynamic data for instant front-ends
ASP.NET providers for membership, roles, etc.
