Disable Data Sampling

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

1. Disable Immuta fingerprinting.

2. Stop all data source health checks.

3. Add the Skip Stats Job tag to all data sources.

These steps will ensure that Immuta queries no data, under any circumstances. Without this sample data, some Immuta features will be unavailable. Sensitive Data Discovery (SDD) cannot be used to automatically detect sensitive data in your data sources, and the following masking policies will not work:

• Masking with format preserving masking

• Masking with k-anonymization

• Masking using randomized response

Advanced Configuration

Fingerprinting

To stop Immuta from running fingerprints on all data sources,

1. Navigate to the App Settings page, and scroll to the Advanced Configuration section.

2. Enter the following YAML:

   Copy

   fingerprints:
     uri: null
     classification:
       enabled: false

3. Click Save.

Data Source Health Checks

To stop Immuta from running data source health checks on all data sources,

1. Navigate to the App Settings page, and scroll to the Advanced Configuration section.

2. Enter the following YAML:

   Copy

   plugins:
     snowflakeHandler:
       config:
         healthCheckQuery: null
     redshiftHandler:
        config:
         healthCheckQuery: null
     trinoHandler:
       config:
         healthCheckQuery: null
     databricksHandler:
       config:
         healthCheckQuery: null
     asaHandler:
       config:
         healthCheckQuery: null

3. Click Save.

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.
