In addition to deleting an item, you can also return the item's attribute values in the same operation, using the ReturnValues parameter.
Unless you specify conditions, the DeleteItem is an idempotent operation; running it multiple times on the same item or attribute does not result in an error response.
Conditional deletes are useful for deleting items only if specific conditions are met. If those conditions are met, DynamoDB performs the delete. Otherwise, the item is not deleted.
Version: (assembly version)
public virtual DeleteItemResponse DeleteItem( String tableName, Dictionary<String, AttributeValue> key, ReturnValue returnValues )
The name of the table from which to delete the item.
A map of attribute names to AttributeValue objects, representing the primary key of the item to delete. For the primary key, you must provide all of the attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.
Use ReturnValues if you want to get the item attributes as they appeared before they were deleted. For DeleteItem, the valid values are: NONE - If ReturnValues is not specified, or if its value is NONE, then nothing is returned. (This setting is the default for ReturnValues.) ALL_OLD - The content of the old item is returned.
|ConditionalCheckFailedException||A condition specified in the operation could not be evaluated.|
|InternalServerErrorException||An error occurred on the server side.|
|ItemCollectionSizeLimitExceededException||An item collection is too large. This exception is only returned for tables that have one or more local secondary indexes.|
|ProvisionedThroughputExceededException||Your request rate is too high. The AWS SDKs for DynamoDB automatically retry requests that receive this exception. Your request is eventually successful, unless your retry queue is too large to finish. Reduce the frequency of requests and use exponential backoff. For more information, go to Error Retries and Exponential Backoff in the Amazon DynamoDB Developer Guide.|
|ResourceNotFoundException||The operation tried to access a nonexistent table or index. The resource might not be specified correctly, or its status might not be ACTIVE.|
