# Setup tab
Fill in the following fields.
| Option | Description |
| ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Connection** | Select a connection type:
Specify the Bootstrap servers from which you want to receive the Kafka streaming data.
Specify the Hadoop cluster configuration from which you want to retrieve the Kafka streaming data. In a Hadoop cluster configuration, you can specify information like host names and ports for HDFS, Job Tracker, security, and other big data cluster components. Multiple servers can be specified if these are part of the same cluster. For information on Hadoop clusters, see Connecting to a Hadoop cluster with the PDI client.
|
| **Client ID** | The unique Client identifier, used to identify and set up a durable connection path to the server to make requests and to distinguish between different clients. |
| **Topic** | The category to which records are published. |
| **Key Field** | In Kafka, all messages can be keyed, allowing for messages to be distributed to partitions based on their keys in a default routing scheme. If no key is present, messages are randomly distributed to partitions. |
| **Message Field** | The individual record contained in a topic. |

## Querying This Documentation
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, and the optional `goal` query parameter:
```
GET https://docs.pentaho.com/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/kafka-producer/options-kafka-producer/setup-tab.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
