Deletes a single item in a table by primary key. You can perform a conditional delete operation that deletes the item if it exists, or if it has an expected attribute value.
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.
For .NET Core this operation is only available in asynchronous form. Please refer to DeleteItemAsync.

public virtual DeleteItemResponse DeleteItem( String tableName, Dictionary<String, AttributeValue> key )
The name of the table from which to delete the item. You can also provide the Amazon Resource Name (ARN) of the table in this parameter.
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 key 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.
| Exception | Condition |
|---|---|
| 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 Amazon Web Services 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. |
| RequestLimitExceededException | Throughput exceeds the current throughput quota for your account. Please contact Amazon Web Services Support to request a quota increase. |
| 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. |
| TransactionConflictException | Operation was rejected because there is an ongoing transaction for the item. |
