# Row grouping tab

![Row grouping tab](https://3411831820-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FAYwCj9fPr1B2pjC11IOQ%2Fuploads%2Fgit-blob-da4f35fd39d1a3f8f5d803baa1292eae84b88a00%2FJobExecutor_step_RowGrouping_tab.png?alt=media)

Specify how to group the result rows by one of the following methods:

* Specific number of rows.
* Specific field.
* Specified duration of time.

You can use the result rows in a transformation or job entry, or you can get the records themselves by using the Get rows from result step in a transformation.

To access the **Field to group rows on** or **Duration time when collecting rows** options, delete the default value in the **Number of rows to send to transformation** option.

| Option                                       | Description                                                                                                                                                                                                                   |
| -------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Number of rows to send to transformation** | Specify a number. After every n number of rows, the job will be executed and these n rows will be passed to the transformation.                                                                                               |
| **Field to group rows on**                   | Specify a field for grouping rows. Rows will be collected in a group as long as the field value stays the same. If the value changes, the job will be executed and the accumulated rows will be passed to the transformation. |
| **Duration time when collecting rows**       | Specify a time in milliseconds. This value is the amount of time the step will spend collecting rows prior to the execution of the job.                                                                                       |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.pentaho.com/pdia-data-integration/9.3-data-integration/pdi-transformation-steps-reference-overview/job-executor/options-job-executor/row-grouping-tab.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
