Settings for DynamoDBContext.

Inheritance Hierarchy


Namespace: Amazon.Util
Assembly: AWSSDK.DynamoDBv2.dll
Version: 3.x.y.z


public class DynamoDBContextConfig

The DynamoDBContextConfig type exposes the following members


Public Property DisableFetchingTableMetadata System.Nullable<System.Boolean>

If true disables fetching table metadata automatically from DynamoDB. Table metadata must be defined by Amazon.DynamoDBv2.DataModel.DynamoDBAttribute attributes and/or in Amazon.AWSConfigsDynamoDB.

Public Property MetadataCachingMode System.Nullable<Amazon.DynamoDBv2.MetadataCachingMode>

The object persistence API relies on an internal cache of the DynamoDB table's metadata to construct and validate requests. This controls how the cache key is derived, which influences when the SDK will call IAmazonDynamoDB.DescribeTable(string) internally to populate the cache.

Public Property RetrieveDateTimeInUtc System.Nullable<System.Boolean>

If true, all System.DateTime properties are retrieved in UTC timezone while reading data from DynamoDB. Else, the local timezone is used.

Public Property TableAliases System.Collections.Generic.Dictionary<System.String, System.String>

A string-to-string dictionary (From-Table to To-Table) used by DynamoDBContext to use a different table from one that is configured for a type. Remapping is done before applying TableNamePrefix.

Public Property TableNamePrefix System.String

Configures the default TableNamePrefix that the DynamoDBContext will use if not manually configured. TableNamePrefix is used after TableAliases have been applied.

Public Property TypeMappings System.Collections.Generic.Dictionary<System.Type, Amazon.Util.TypeMapping>

A Type-to-TypeMapping (type to TypeMapping defining its DynamoDB conversion) used by DynamoDBContext to modify or configure a particular type.



Asynchronous operations (methods ending with Async) in the table below are for .NET 4.5 or higher. For .NET 3.5 the SDK follows the standard naming convention of BeginMethodName and EndMethodName to indicate asynchronous operations - these method pairs are not shown in the table below.

Public Method AddAlias(TableAlias)

Adds a TableAlias to the TableAliases property. An exception is thrown if there is already a TableAlias with the same FromTable configured.

Public Method AddMapping(TypeMapping)

Adds a TypeMapping to the TypeMappings property. An exception is thrown if there is already a TypeMapping with the same Type configured.
