<p>Disables server-side encryption (SSE) for the delivery stream. </p> <p>This operation is asynchronous. It returns immediately. When you invoke it, Kinesis Data Firehose first sets the encryption status of the stream to <code>DISABLING</code>, and then to <code>DISABLED</code>. You can continue to read and write data to your stream while its status is <code>DISABLING</code>. It can take up to 5 seconds after the encryption status changes to <code>DISABLED</code> before all records written to the delivery stream are no longer subject to encryption. To find out whether a record or a batch of records was encrypted, check the response elements <a>PutRecordOutput$Encrypted</a> and <a>PutRecordBatchOutput$Encrypted</a>, respectively.</p> <p>To check the encryption state of a delivery stream, use <a>DescribeDeliveryStream</a>. </p> <p>If SSE is enabled using a customer managed CMK and then you invoke <code>StopDeliveryStreamEncryption</code>, Kinesis Data Firehose schedules the related KMS grant for retirement and then retires it after it ensures that it is finished delivering records to the destination.</p> <p>The <code>StartDeliveryStreamEncryption</code> and <code>StopDeliveryStreamEncryption</code> operations have a combined limit of 25 calls per delivery stream per 24 hours. For example, you reach the limit if you call <code>StartDeliveryStreamEncryption</code> 13 times and <code>StopDeliveryStreamEncryption</code> 12 times for the same delivery stream in a 24-hour period.</p>
