Table

The Azure CloudTable in which the entities will be stored. Repositories can use this property to implement the read operations beyond the simple Get(ITableEntity) and List() methods.

Declaration
protected readonly Lazy<CloudTable> Table
Field Value
Type Description
System.Lazy<Microsoft.Azure.Cosmos.Table.CloudTable>

TableName

By default, TableName will be the typeof(TEntity).Name (which means the table name will change if you rename the entity class). If you wish to have a stable name, then override and return the desired name. Either way, the actual table name may include a prefix as governed by the TContext when it prepares the table.

Declaration
protected virtual string TableName { get; }
Property Value
Type Description
System.String

CalculatePartitionKeyFor(TEntity)

Override to return a suitable PartitionKey derived from the entity. This should be a function of the other properties in the entity so that a fundamental change to the partition can be detected and handled allowing for an entity to be moved properly (i.e. the entity's actual PartitionKey value should be treated as Read-Only).

Declaration
protected abstract string CalculatePartitionKeyFor(TEntity entity)
Parameters
Type Name Description
TEntity entity
Returns
Type Description
System.String

NewUniqueId()

Override to provide some other means of generating unique IDs. Default is using Guid.NewGuid() to reduce 3rd-party dependencies, but consider overriding and using a CombGuid algorithm or something similar. Do be sure this will generate a unique identifier within the scope of this TEntity's persistent store.

Declaration
protected virtual string NewUniqueId()
Returns
Type Description
System.String
