Source

Use the Source API to clear the AWS Lake Formation permission cache for AWS Glue Data Catalog sources. The Source API is supported only for AWS Glue Data Catalog sources.

Dremio maintains a cache of permissions defined in AWS Lake Formation with a one-hour expiry time. When the cache for the queried table expires, Dremio requests permission information from AWS Lake Formation. After changing permissions on the AWS Lake Formation side, use the Source API to immediately invalidate Dremio's AWS Lake Formation permission cache.
