Note The Table service REST API operations also return an ETag value that it derives from the last-modified timestamp (LMT).

In this document you will notice the terms ETag and LMT interchangeably because they refer to the same underlying data.

For more information about the internal details of the Table service, and in particular how the service manages partitions, see the paper Microsoft Azure Storage: A Highly Available Cloud Storage Service with Strong Consistency.

In the Table service, Entity Group Transactions (EGTs) are the only built-in mechanism for performing atomic updates across multiple entities.

If you are new to Azure Storage and the Table service, first read Introduction to Microsoft Azure Storage and Get started with Azure Table Storage using . Although the focus of this guide is on the Table service, it will include some discussion of the Azure Queue and Blob services, and how you might use them along with the Table service in a solution. As you might expect from the name, the Table service uses a tabular format to store data.

In the standard terminology, each row of the table represents an entity, and the columns store the various properties of that entity.

If you have previously designed schemas for relational databases, these considerations will be familiar to you, but while there are some similarities between the Azure Table service storage model and relational models, there are also many important differences.

These differences typically lead to different designs that may look counter-intuitive or wrong to someone familiar with relational databases, but that do make good sense if you are designing for a No SQL key/value store such as the Azure Table service.

Every entity stored in a table must have a unique combination of Partition Key and Row Key.

As with keys in a relational database table, the Partition Key and Row Key values are indexed to create a clustered index that enables fast look-ups; however, the Table service does not create any secondary indexes so these are the only two indexed properties (some of the patterns described later show how you can work around this apparent limitation).

So far, this design looks similar to a table in a relational database with the key differences being the mandatory columns, and the ability to store multiple entity types in the same table.
