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.

Deletes a delivery stream and its data.
You can delete a delivery stream only if it is in one of the following states: ACTIVE, DELETING, CREATING_FAILED, or DELETING_FAILED. You can't delete a delivery stream that is in the CREATING state. To check the state of a delivery stream, use DescribeDeliveryStream.
DeleteDeliveryStream is an asynchronous API. When an API request to DeleteDeliveryStream succeeds, the delivery stream is marked for deletion, and it goes into the DELETING state.While the delivery stream is in the DELETING state, the service might continue to accept records, but it doesn't make any guarantees with respect to delivering the data. Therefore, as a best practice, first stop any applications that are sending records before you delete a delivery stream.
Removal of a delivery stream that is in the DELETING state is a low priority operation for the service. A stream may remain in the DELETING state for several minutes. Therefore, as a best practice, applications should not wait for streams in the DELETING state to be removed.

Describes the specified delivery stream and its status. For example, after your delivery stream is created, call DescribeDeliveryStream to see whether the delivery stream is ACTIVE and therefore ready for data to be sent to it.
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. If the status is DELETING_FAILED, you can force deletion by invoking DeleteDeliveryStream again but with DeleteDeliveryStreamInput$AllowForceDelete set to true.

Lists your delivery streams in alphabetical order of their names.
The number of delivery streams might be too large to return using a single call to ListDeliveryStreams. You can limit the number of delivery streams returned, using the Limit parameter. To determine whether there are more delivery streams to list, check the value of HasMoreDeliveryStreams in the output. If there are more delivery streams to list, you can request them by calling this operation again and setting the ExclusiveStartDeliveryStreamName parameter to the name of the last delivery stream returned in the last call.

Writes a single data record into an Amazon Firehose delivery stream. To write multiple data records into a delivery stream, use PutRecordBatch. Applications using these operations are referred to as producers.
By default, each delivery stream can take in up to 2,000 transactions per second, 5,000 records per second, or 5 MB per second. If you use PutRecord and PutRecordBatch, the limits are an aggregate across these two operations for each delivery stream. For more information about limits and how to request an increase, see Amazon Firehose Limits.
Firehose accumulates and publishes a particular metric for a customer account in one minute intervals. It is possible that the bursts of incoming bytes/records ingested to a delivery stream last only for a few seconds. Due to this, the actual spikes in the traffic might not be fully visible in the customer's 1 minute CloudWatch metrics.
You must specify the name of the delivery stream and the data record when using PutRecord. The data record consists of a data blob that can be up to 1,000 KiB in size, and any kind of data. For example, it can be a segment from a log file, geographic location data, website clickstream data, and so on.
Firehose buffers records before delivering them to the destination. To disambiguate the data blobs at the destination, a common solution is to use delimiters in the data, such as a newline (
The PutRecord operation returns a RecordId, which is a unique string assigned to each record. Producer applications can use this ID for purposes such as auditability and investigation.
If the PutRecord operation throws a ServiceUnavailableException, the API is automatically reinvoked (retried) 3 times. If the exception persists, it is possible that the throughput limits have been exceeded for the delivery stream.
Re-invoking the Put API operations (for example, PutRecord and PutRecordBatch) can result in data duplicates. For larger data assets, allow for a longer time out before retrying Put API operations.
Data records sent to Firehose are stored for 24 hours from the time they are added to a delivery stream as it tries to send the records to the destination. If the destination is unreachable for more than 24 hours, the data is no longer available.
Don't concatenate two or more base64 strings to form the data fields of your records. Instead, concatenate the raw data, then perform base64 encoding.

Writes multiple data records into a delivery stream in a single call, which can achieve higher throughput per producer than when writing single records. To write single data records into a delivery stream, use PutRecord. Applications using these operations are referred to as producers.

For information about service quota, see Amazon Firehose Quota.
Each PutRecordBatch request supports up to 500 records. Each record in the request can be as large as 1,000 KB (before base64 encoding), up to a limit of 4 MB for the entire request. These limits cannot be changed.

The PutRecordBatch response includes a count of failed records, FailedPutCount, and an array of responses, RequestResponses. Even if the PutRecordBatch call succeeds, the value of FailedPutCount may be greater than 0, indicating that there are records for which the operation didn't succeed. Each entry in the RequestResponses array provides additional information about the processed record. It directly correlates with a record in the request array using the same ordering, from the top to the bottom. The response array always includes the same number of records as the request array. RequestResponses includes both successfully and unsuccessfully processed records. Firehose tries to process all records in each PutRecordBatch request. A single record failure does not stop the processing of subsequent records.
A successfully processed record includes a RecordId value, which is unique for the record. An unsuccessfully processed record includes ErrorCode and ErrorMessage values. ErrorCode reflects the type of error, and is one of the following values: ServiceUnavailableException or InternalFailure. ErrorMessage provides more detailed information about the error.
If there is an internal server error or a timeout, the write might have completed or it might have failed. If FailedPutCount is greater than 0, retry the request, resending only those records that might have failed processing. This minimizes the possible duplicate records and also reduces the total bytes sent (and corresponding charges). We recommend that you handle any duplicates at the destination.
If PutRecordBatch throws ServiceUnavailableException, the API is automatically reinvoked (retried) 3 times. If the exception persists, it is possible that the throughput limits have been exceeded for the delivery stream.

Enables server-side encryption (SSE) for the delivery stream.
This operation is asynchronous. It returns immediately. When you invoke it, 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, Firehose schedules the grant it had on the old CMK for retirement. If the new CMK is of type CUSTOMER_MANAGED_CMK, Firehose creates a grant that enables it to use the new CMK to encrypt and decrypt data and to manage the grant.
For the KMS grant creation to be successful, the Firehose API operations StartDeliveryStreamEncryption and CreateDeliveryStream should not be called with session credentials that are more than 6 hours old.
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 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.

Disables server-side encryption (SSE) for the delivery stream.
This operation is asynchronous. It returns immediately. When you invoke it, Firehose first sets the encryption status of the stream to DISABLING, and then to DISABLED. You can continue to read and write data to your stream while its status is DISABLING. It can take up to 5 seconds after the encryption status changes to DISABLED 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 PutRecordOutput$Encrypted and PutRecordBatchOutput$Encrypted, respectively.
To check the encryption state of a delivery stream, use DescribeDeliveryStream.
If SSE is enabled using a customer managed CMK and then you invoke StopDeliveryStreamEncryption, Firehose schedules the related KMS grant for retirement and then retires it after it ensures that it is finished delivering records to the destination.
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.

Adds or updates tags for the specified delivery stream. A tag is a key-value pair that you can define and assign to Amazon Web Services resources. If you specify a tag that already exists, the tag value is replaced with the value that you specify in the request. Tags are metadata. For example, you can add friendly names and descriptions or other types of information that can help you distinguish the delivery stream. For more information about tags, see Using Cost Allocation Tags in the Amazon Web Services Billing and Cost Management User Guide.
Each delivery stream can have up to 50 tags.
This operation has a limit of five transactions per second per account.

Updates the specified destination of the specified delivery stream.
Use this operation to change the destination type (for example, to replace the Amazon S3 destination with Amazon Redshift) or change the parameters associated with a destination (for example, to change the bucket name of the Amazon S3 destination). The update might not occur immediately. The target delivery stream remains active while the configurations are updated, so data writes to the delivery stream can continue during this process. The updated configurations are usually effective within a few minutes.
Switching between Amazon OpenSearch Service and other services is not supported. For an Amazon OpenSearch Service destination, you can only update to another Amazon OpenSearch Service destination.
If the destination type is the same, Firehose merges the configuration parameters specified with the destination configuration that already exists on the delivery stream. If any of the parameters are not specified in the call, the existing values are retained. For example, in the Amazon S3 destination, if EncryptionConfiguration is not specified, then the existing EncryptionConfiguration is maintained on the destination.
If the destination type is not the same, for example, changing the destination from Amazon S3 to Amazon Redshift, Firehose does not merge any parameters. In this case, all parameters must be specified.
Firehose uses CurrentDeliveryStreamVersionId to avoid race conditions and conflicting merges. This is a required field, and the service updates the configuration only if the existing configuration has a version ID that matches. After the update is applied successfully, the version ID is updated, and can be retrieved using DescribeDeliveryStream. Use the new version ID to set CurrentDeliveryStreamVersionId in the next call.
