# Modify Snowflake warehouse

You can use the Modify Snowflake warehouse job entry to edit warehouse settings. For more information about working with Snowflake in PDI, see [PDI and Snowflake](/pdia-data-integration/9.3-data-integration/advanced-topics-pentaho-data-integration-overview/pdi-and-snowflake-cp.md)

Modifying a warehouse is useful if your data and usage needs change through the day, week, month, or year. For example, your users might only perform simple queries which require a small warehouse. However, to meet your ETL service-level agreements (SLA), you may need a larger warehouse during the ETL process. Using this job entry, you can modify the warehouse at the beginning of the ETL process to scale it up, and then modify it to scale it back down when the ETL process is complete.

For more information about Snowflake warehouse settings, see the [Snowflake](https://docs.snowflake.net/manuals/index.html) documentation.

## 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/9.3-data-integration/pdi-job-entries-reference-overview/modify-warehouse-pdi-job-entry.md?ask=<question>&goal=<endgoal>
```

`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.
