| **Input name**  | <p>The input name is received from the Kinesis streams. The following are received by default:</p><ul><li><strong>message</strong></li></ul><p>The individual message contained in a record. Each record consists of a sequence number, a partition key, and a message.</p><ul><li><strong>partition key</strong></li></ul><p>Used to group data by shard within a stream. The partition key is associated with each data record to determine which shard a given data record belongs to.</p><ul><li><strong>sequence number</strong></li></ul><p>A sequential ID number assigned to each record. It uniquely identifies each record within the partition.</p><ul><li><strong>subsequence number</strong></li></ul><p>Because all subrecords within a record have the same sequence number, additional data is stored with the checkpoint if you need to distinguish between subrecords. This additional data is the subsequence number.</p><ul><li><strong>shard id</strong></li></ul><p>The unique identifier of the shard within the stream.</p> |
| **Output name** | The **Output name** can be mapped to subscriber and member requirements.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            |
| **Type**        | <p>The <strong>Type</strong> field defines the data format for streaming the record. You must choose the same data type that produced the records. This field applies to the message input names. Options include:</p><ul><li>String</li><li>Boolean</li><li>Number</li><li>Integer</li><li>Binary</li></ul><p>The default value is String.</p>                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     |

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.pentaho.com/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/kinesis-consumer/options-kinesis-consumer/fields-tab-kinesis-consumer.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
