# Disable Immuta from Sampling Raw Data

If you want to disable the metadata collection that requires sampling data, you must

1. [Stop all data source health checks.](#data-source-health-checks)
2. [Add the `Skip Stats Job` tag to all data sources.](#skip-stats-job-tag)

These steps will ensure that Immuta queries no data, under any circumstances. Without this sample data, the following masking policies ([which are only available in the Snowflake integration](/saas/govern/secure-your-data/authoring-policies-in-secure/data-policies/reference-guides/masking-matrix-functions.md#types-limited-to-snowflake)) will not work:

* Masking with format preserving masking
* Masking using randomized response

## Data Source Health Checks

Reach out to your Immuta representative to disable health checks on all data sources.

## Skip Stats Job Tag

Tag each data source with the seeded `Skip Stats Job` tag to stop Immuta from collecting a sample and running table stats on the sample. You can tag data sources as you create them in the UI or [via the Immuta API](/saas/developer-guides/api-intro/immuta-v2-api/data-source.md#options-object).

Note that data sources automatically skip the stats job upon registration, without the `Skip Stats Job` tag, as long as there are no active policies requiring them. The following policies require stats:

* Column masking with randomized response
* Column masking with format preserving masking
* Column masking with rounding
* Column masking with reversibility
* Row minimization

# Agent Instructions: 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:

```
GET https://documentation.immuta.com/saas/configuration/integrations/data-and-integrations/registering-metadata/data-source-settings/how-to-guides/disable-data-sampling.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.
