Creates a Firehose delivery stream.

By default, you can create up to 50 delivery streams per Amazon Web Services Region.

This is an asynchronous operation that immediately returns. The initial status of the delivery stream is CREATING. After the delivery stream is created, its status is ACTIVE and it now accepts data. If the delivery stream creation fails, the status transitions to CREATING_FAILED. Attempts to send data to a delivery stream that is not in the ACTIVE state cause an exception. To check the state of a delivery stream, use DescribeDeliveryStream.

If the status of a delivery stream is CREATING_FAILED, this status doesn't change, and you can't invoke CreateDeliveryStream again on it. However, you can invoke the DeleteDeliveryStream operation to delete it.

A Firehose delivery stream can be configured to receive records directly from providers using PutRecord or PutRecordBatch, or it can be configured to use an existing Kinesis stream as its source. To specify a Kinesis data stream as input, set the DeliveryStreamType parameter to KinesisStreamAsSource, and provide the Kinesis stream Amazon Resource Name (ARN) and role ARN in the KinesisStreamSourceConfiguration parameter.

To create a delivery stream with server-side encryption (SSE) enabled, include DeliveryStreamEncryptionConfigurationInput in your request. This is optional. You can also invoke StartDeliveryStreamEncryption to turn on SSE for an existing delivery stream that doesn't have SSE enabled.

A delivery stream is configured with a single destination, such as Amazon Simple Storage Service (Amazon S3), Amazon Redshift, Amazon OpenSearch Service, Amazon OpenSearch Serverless, Splunk, and any custom HTTP endpoint or HTTP endpoints owned by or supported by third-party service providers, including Datadog, Dynatrace, LogicMonitor, MongoDB, New Relic, and Sumo Logic. You must specify only one of the following destination configuration parameters: ExtendedS3DestinationConfiguration, S3DestinationConfiguration, ElasticsearchDestinationConfiguration, RedshiftDestinationConfiguration, or SplunkDestinationConfiguration.

When you specify S3DestinationConfiguration, you can also provide the following optional values: BufferingHints, EncryptionConfiguration, and CompressionFormat. By default, if no BufferingHints value is provided, Firehose buffers data up to 5 MB or for 5 minutes, whichever condition is satisfied first. BufferingHints is a hint, so there are some cases where the service cannot adhere to these conditions strictly. For example, record boundaries might be such that the size is a little over or under the configured buffering size. By default, no encryption is performed. We strongly recommend that you enable encryption to ensure secure data storage in Amazon S3.

A few notes about Amazon Redshift as a destination:

• An Amazon Redshift destination requires an S3 bucket as intermediate location. Firehose first delivers data to Amazon S3 and then uses COPY syntax to load data into an Amazon Redshift table. This is specified in the RedshiftDestinationConfiguration.S3Configuration parameter.

• The compression formats SNAPPY or ZIP cannot be specified in RedshiftDestinationConfiguration.S3Configuration because the Amazon Redshift COPY operation that reads from the S3 bucket doesn't support these compression formats.

• We strongly recommend that you use the user name and password you provide exclusively with Firehose, and that the permissions for the account are restricted for Amazon Redshift INSERT permissions.

Firehose assumes the IAM role that is configured as part of the destination. The role should allow the Firehose principal to assume the role, and the role should have permissions that allow the service to deliver the data. For more information, see Grant Firehose Access to an Amazon S3 Destination in the Amazon Firehose Developer Guide.
