  • Method Details

    • createDeliveryStream

      public CreateDeliveryStreamResult createDeliveryStream(CreateDeliveryStreamRequest createDeliveryStreamRequest)

      Creates a delivery stream.

      CreateDeliveryStream 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. 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.

      The name of a delivery stream identifies it. You can't have two delivery streams with the same name in the same region. Two delivery streams in different AWS accounts or different regions in the same AWS account can have the same name.

      By default, you can create up to 20 delivery streams per region.

      A delivery stream can only be configured with a single destination, Amazon S3, Amazon Elasticsearch Service, or Amazon Redshift. For correct CreateDeliveryStream request syntax, specify only one destination configuration parameter: either S3DestinationConfiguration, ElasticsearchDestinationConfiguration, or RedshiftDestinationConfiguration.

      As part of S3DestinationConfiguration, optional values BufferingHints, EncryptionConfiguration, and CompressionFormat can be provided. By default, if no BufferingHints value is provided, Firehose buffers data up to 5 MB or for 5 minutes, whichever condition is satisfied first. Note that BufferingHints is a hint, so there are some cases where the service cannot adhere to these conditions strictly; for example, record boundaries are 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 RedshiftDestinationConfiguration:

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

      • 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 the username and password provided is used exclusively for Firehose purposes, 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 destinations. The IAM role should allow the Firehose principal to assume the role, and the role should have permissions that allows the service to deliver the data. For more information, see Amazon S3 Bucket Access in the Amazon Kinesis Firehose Developer Guide.

      Specified by:
      createDeliveryStream in interface AmazonKinesisFirehose
      Parameters:
      createDeliveryStreamRequest - Contains the parameters for CreateDeliveryStream.
      Returns:
      Result of the CreateDeliveryStream operation returned by the service.
      Throws:
      InvalidArgumentException - The specified input parameter has an value that is not valid.
      LimitExceededException - You have already reached the limit for a requested resource.
      ResourceInUseException - The resource is already in use and not available for this operation.
    • deleteDeliveryStream

      public DeleteDeliveryStreamResult deleteDeliveryStream(DeleteDeliveryStreamRequest deleteDeliveryStreamRequest)

      Deletes a delivery stream and its data.

      You can delete a delivery stream only if it is in ACTIVE or DELETING state, and not in the CREATING state. While the deletion request is in process, the delivery stream is in the DELETING state.

      To check the state of a delivery stream, use DescribeDeliveryStream.

      While the delivery stream is DELETING state, the service may continue to accept the records, but the service doesn't make any guarantees with respect to delivering the data. Therefore, as a best practice, you should first stop any applications that are sending records before deleting a delivery stream.

      Specified by:
      deleteDeliveryStream in interface AmazonKinesisFirehose
      Parameters:
      deleteDeliveryStreamRequest - Contains the parameters for DeleteDeliveryStream.
      Returns:
      Result of the DeleteDeliveryStream operation returned by the service.
      Throws:
      ResourceInUseException - The resource is already in use and not available for this operation.
      ResourceNotFoundException - The specified resource could not be found.
    • describeDeliveryStream

      public DescribeDeliveryStreamResult describeDeliveryStream(DescribeDeliveryStreamRequest describeDeliveryStreamRequest)

      Describes the specified delivery stream and gets the status. For example, after your delivery stream is created, call DescribeDeliveryStream to see if the delivery stream is ACTIVE and therefore ready for data to be sent to it.

      Specified by:
      describeDeliveryStream in interface AmazonKinesisFirehose
      Parameters:
      describeDeliveryStreamRequest - Contains the parameters for DescribeDeliveryStream.
      Returns:
      Result of the DescribeDeliveryStream operation returned by the service.
      Throws:
      ResourceNotFoundException - The specified resource could not be found.
    • listDeliveryStreams

      public ListDeliveryStreamsResult listDeliveryStreams(ListDeliveryStreamsRequest listDeliveryStreamsRequest)

      Lists your delivery streams.

      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 specifying the name of the last delivery stream returned in the call in the ExclusiveStartDeliveryStreamName parameter of a subsequent call.

      Specified by:
      listDeliveryStreams in interface AmazonKinesisFirehose
      Parameters:
      listDeliveryStreamsRequest - Contains the parameters for ListDeliveryStreams.
      Returns:
      Result of the ListDeliveryStreams operation returned by the service.
    • putRecord

      public PutRecordResult putRecord(PutRecordRequest putRecordRequest)

      Writes a single data record into an Amazon Kinesis 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. Note that 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 Kinesis Firehose Limits.

      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 KB in size, and any kind of data, for example, a segment from a log file, geographic location data, web site clickstream data, etc.

      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 (\n) or some other character unique within the data. This allows the consumer application(s) to parse individual data items when reading the data from the destination.

      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, back off and retry. If the exception persists, it is possible that the throughput limits have been exceeded for the delivery stream.

      Data records sent to Firehose are stored for 24 hours from the time they are added to a delivery stream as it attempts to send the records to the destination. If the destination is unreachable for more than 24 hours, the data is no longer available.

      Specified by:
      putRecord in interface AmazonKinesisFirehose
      Parameters:
      putRecordRequest - Contains the parameters for PutRecord.
      Returns:
      Result of the PutRecord operation returned by the service.
      Throws:
      ResourceNotFoundException - The specified resource could not be found.
      InvalidArgumentException - The specified input parameter has an value that is not valid.
      ServiceUnavailableException - The service is unavailable, back off and retry the operation. If you continue to see the exception, throughput limits for the delivery stream may have been exceeded. For more information about limits and how to request an increase, see Amazon Kinesis Firehose Limits.
    • putRecordBatch

      public PutRecordBatchResult putRecordBatch(PutRecordBatchRequest putRecordBatchRequest)

      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.

      Each PutRecordBatch request supports up to 500 records. Each record in the request can be as large as 1,000 KB (before 64-bit encoding), up to a limit of 4 MB for the entire request. 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. Note that 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 Kinesis Firehose Limits.

      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 KB in size, and any kind of data, for example, a segment from a log file, geographic location data, web site 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 (\n) or some other character unique within the data. This allows the consumer application(s) to parse individual data items when reading the data from the destination.

      The PutRecordBatch response includes a count of any failed records, FailedPutCount, and an array of responses, RequestResponses. The FailedPutCount value is a count of records that failed. Each entry in the RequestResponses array gives additional information of the processed record. Each entry in RequestResponses directly correlates with a record in the request array using the same ordering, from the top to the bottom of the request and response. RequestResponses always includes the same number of records as the request array. RequestResponses both successfully and unsuccessfully processed records. Firehose attempts 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 a unique value identified 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: ServiceUnavailable or InternalFailure. ErrorMessage provides more detailed information about the error.

      If FailedPutCount is greater than 0 (zero), retry the request. A retry of the entire batch of records is possible; however, we strongly recommend that you inspect the entire response and resend only those records that failed processing. This minimizes duplicate records and also reduces the total bytes sent (and corresponding charges).

      If the PutRecordBatch operation throws a ServiceUnavailableException, back off and retry. If the exception persists, it is possible that the throughput limits have been exceeded for the delivery stream.

      Data records sent to Firehose are stored for 24 hours from the time they are added to a delivery stream as it attempts to send the records to the destination. If the destination is unreachable for more than 24 hours, the data is no longer available.

      Specified by:
      putRecordBatch in interface AmazonKinesisFirehose
      Parameters:
      putRecordBatchRequest - Contains the parameters for PutRecordBatch.
      Returns:
      Result of the PutRecordBatch operation returned by the service.
      Throws:
      ResourceNotFoundException - The specified resource could not be found.
      InvalidArgumentException - The specified input parameter has an value that is not valid.
      ServiceUnavailableException - The service is unavailable, back off and retry the operation. If you continue to see the exception, throughput limits for the delivery stream may have been exceeded. For more information about limits and how to request an increase, see Amazon Kinesis Firehose Limits.
    • updateDestination

      public UpdateDestinationResult updateDestination(UpdateDestinationRequest updateDestinationRequest)

      Updates the specified destination of the specified delivery stream. Note: Switching between Elasticsearch and other services is not supported. For Elasticsearch destination, you can only update an existing Elasticsearch destination with this operation.

      This operation can be used to change the destination type (for example, to replace the Amazon S3 destination with Amazon Redshift) or change the parameters associated with a given destination (for example, to change the bucket name of the Amazon S3 destination). The update may 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 normally effective within a few minutes.

      If the destination type is the same, Firehose merges the configuration parameters specified in the UpdateDestination request with the destination configuration that already exists on the delivery stream. If any of the parameters are not specified in the update request, then the existing configuration parameters 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 the CurrentDeliveryStreamVersionId to avoid race conditions and conflicting merges. This is a required field in every request and the service only updates the configuration if the existing configuration matches the VersionId. After the update is applied successfully, the VersionId is updated, which can be retrieved with the DescribeDeliveryStream operation. The new VersionId should be uses to set CurrentDeliveryStreamVersionId in the next UpdateDestination operation.

      Specified by:
      updateDestination in interface AmazonKinesisFirehose
      Parameters:
      updateDestinationRequest - Contains the parameters for UpdateDestination.
      Returns:
      Result of the UpdateDestination operation returned by the service.
      Throws:
      InvalidArgumentException - The specified input parameter has an value that is not valid.
      ResourceInUseException - The resource is already in use and not available for this operation.
      ResourceNotFoundException - The specified resource could not be found.
      ConcurrentModificationException - Another modification has already happened. Fetch VersionId again and use it to update the destination.
    • getCachedResponseMetadata

      public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
      Returns additional metadata for a previously executed successful, request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

      Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing the request.

      Specified by:
      getCachedResponseMetadata in interface AmazonKinesisFirehose
      Parameters:
      request - The originally executed request
      Returns:
      The response metadata for the specified request, or null if none is available.
