WebHashing keys in Data Vault allows integration keys to be loaded in a deterministic way from multiple sources in parallel. This also removes the need for key lookups between related entities. Hashing row checksums for identifying changes allows the load process to compare a single generated hash to identify if an attribute has changed for a key.
