Hubs make key management easier (natural keys from hubs can be converted to surrogate keys via Identity columns).

In this blog https://databricks.com/blog/2022/06/24/prescriptive-guidance-for-implementing-a-data-vault-model-on-the-databricks-lakehouse-platform.html

It is mention that "Data Vault modeling recommends using a hash of business keys as the primary keys. Databricks supports hash, md5, and SHA functions out of the box to support business keys.".

If my HUB primary keys are HASH then how it can be converted to identity columns in Gold Layer ???

Thanks
