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.

2. 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, the following masking policies (which are only available in the Snowflake integration) 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.

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
