An Amazon Kinesis data object is a physical data object that represents data in an Amazon Kinesis Data Firehose Delivery Stream. After you create an Amazon Kinesis connection, create an Amazon Kinesis data object to write to Amazon Kinesis Data Firehose.
Kinesis Data Firehose is a real-time data stream processing option that Amazon Kinesis offers within the AWS ecosystem. Kinesis Data Firehose allows batching, encrypting, and compressing of data. Kinesis Data Firehose can automatically scale to meet system needs.
When you configure the Amazon Kinesis data object, specify the name of the Data Firehose Delivery Stream that you write to. You can specify the Kinesis Data Firehose Delivery Stream name or use a regular expression for the stream name pattern. If the input has multiple partitions, you can create multiple Kinesis Data Firehose Delivery Streams to the same target and send the data from these partitions to the individual delivery streams based on the pattern you specify in the stream name.
After you create the data object, create a data object write operation to write data to an Amazon Kinesis Data Firehose Delivery Stream. You can then add the data object write operation as a target in Streaming mappings.
When you configure the data operation properties, specify the format in which the data object writes data. When you write to Amazon Data Firehose targets, you can specify JSON or binary as the format.
When you specify JSON format, you must provide a sample file.
You can pass any payload format directly from source to target in Streaming mappings. You can project columns in binary format pass a payload from source to target in its original form or to pass a payload format that is not supported.
Streaming mappings can read, process, and write hierarchical data. You can use array, struct, and map complex data types to process the hierarchical data. You assign complex data types to ports in a mapping to flow hierarchical data. Ports that flow hierarchical data are called complex ports.
When you run a mapping to write data to an Amazon Kinesis Data Firehose Delivery Stream, the data object uses the AWS Firehose SDK to write data.
You cannot run a mapping with an Amazon Kinesis data object on MapR and Azure HDInsight distributions.
