start-delivery-stream-encryption

Description

Enables server-side encryption (SSE) for the delivery stream.

This operation is asynchronous. It returns immediately. When you invoke it, Kinesis Data Firehose first sets the encryption status of the stream to ENABLING , and then to ENABLED . The encryption status of a delivery stream is the Status property in DeliveryStreamEncryptionConfiguration . If the operation fails, the encryption status changes to ENABLING_FAILED . You can continue to read and write data to your delivery stream while the encryption status is ENABLING , but the data is not encrypted. It can take up to 5 seconds after the encryption status changes to ENABLED before all records written to the delivery stream are encrypted. To find out whether a record or a batch of records was encrypted, check the response elements PutRecordOutput$Encrypted and PutRecordBatchOutput$Encrypted , respectively.

To check the encryption status of a delivery stream, use DescribeDeliveryStream .

Even if encryption is currently enabled for a delivery stream, you can still invoke this operation on it to change the ARN of the CMK or both its type and ARN. If you invoke this method to change the CMK, and the old CMK is of type CUSTOMER_MANAGED_CMK , Kinesis Data Firehose schedules the grant it had on the old CMK for retirement. If the new CMK is of type CUSTOMER_MANAGED_CMK , Kinesis Data Firehose creates a grant that enables it to use the new CMK to encrypt and decrypt data and to manage the grant.

If a delivery stream already has encryption enabled and then you invoke this operation to change the ARN of the CMK or both its type and ARN and you get ENABLING_FAILED , this only means that the attempt to change the CMK failed. In this case, encryption remains enabled with the old CMK.

If the encryption status of your delivery stream is ENABLING_FAILED , you can invoke this operation again with a valid CMK. The CMK must be enabled and the key policy mustn't explicitly deny the permission for Kinesis Data Firehose to invoke KMS encrypt and decrypt operations.

You can enable SSE for a delivery stream only if it's a delivery stream that uses DirectPut as its source.

The StartDeliveryStreamEncryption and StopDeliveryStreamEncryption operations have a combined limit of 25 calls per delivery stream per 24 hours. For example, you reach the limit if you call StartDeliveryStreamEncryption 13 times and StopDeliveryStreamEncryption 12 times for the same delivery stream in a 24-hour period.

Synopsis

  start-delivery-stream-encryption
--delivery-stream-name <value>
[--delivery-stream-encryption-configuration-input <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--delivery-stream-name (string)

The name of the delivery stream for which you want to enable server-side encryption (SSE).

--delivery-stream-encryption-configuration-input (structure)

Used to specify the type and Amazon Resource Name (ARN) of the KMS key needed for Server-Side Encryption (SSE).

KeyARN -> (string)

If you set KeyType to CUSTOMER_MANAGED_CMK , you must specify the Amazon Resource Name (ARN) of the CMK. If you set KeyType to AWS_OWNED_CMK , Kinesis Data Firehose uses a service-account CMK.

KeyType -> (string)

Indicates the type of customer master key (CMK) to use for encryption. The default setting is AWS_OWNED_CMK . For more information about CMKs, see Customer Master Keys (CMKs) . When you invoke CreateDeliveryStream or StartDeliveryStreamEncryption with KeyType set to CUSTOMER_MANAGED_CMK, Kinesis Data Firehose invokes the Amazon KMS operation CreateGrant to create a grant that allows the Kinesis Data Firehose service to use the customer managed CMK to perform encryption and decryption. Kinesis Data Firehose manages that grant.

When you invoke StartDeliveryStreamEncryption to change the CMK for a delivery stream that is encrypted with a customer managed CMK, Kinesis Data Firehose schedules the grant it had on the old CMK for retirement.

You can use a CMK of type CUSTOMER_MANAGED_CMK to encrypt up to 500 delivery streams. If a CreateDeliveryStream or StartDeliveryStreamEncryption operation exceeds this limit, Kinesis Data Firehose throws a LimitExceededException .

Warning

To encrypt your delivery stream, use symmetric CMKs. Kinesis Data Firehose doesn't support asymmetric CMKs. For information about symmetric and asymmetric CMKs, see About Symmetric and Asymmetric CMKs in the AWS Key Management Service developer guide.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
