The

masking

task uses the H2 database to stage record IDs, data subset for simple entities, entities with junction objects, multipath relationships, and lookup based relationships, and masking fields.

The H2 staging database installer is packaged with the Secure Agent. You can run the H2 package installer to install the staging connection. You can either start the staging database connection from the

Schedule

page of the

masking

task wizard, or manually run the H2 startup script.

You can view the subset record count in the logs. The task reads the record IDs that are selected for subset from the staging database and uses standard API to read those records from the source. The task uses standard or bulk API to load data into the target.
