When implementing Azure tables there are a few things to remember. An entity can have up to 255 properties, including three system properties: PartitionKey, RowKey, and Timestamp.
You are responsible for inserting and updating the values of PartitionKey and RowKey. The server manages the value of Timestamp, which cannot be modified. Together the PartitionKey and RowKey must uniquely identify every entity within a table.
Currently, Azure PowerShell does not provide cmdlets to manage table entities directly. To perform operations on table entities, you can use the classes given in the Azure Storage Client Library for .NET. Your practical exercise will provide some example code.
