It helps 'gate' the process, so that (for example) only authorized users can set a model to be the newest Production version of a model - that's not something just anyone should be able to do!</P><P></P><P>The Registry can trigger webhooks when a model enters a new state, for example to run a testing notebook when a new Staging candidate appears.</P><P></P><P>It also helps serve as a single source of truth: what's the current production model? rather than pass around the run ID "abc123456..." informally, the stage tags in the Registry let any process look up the 'latest production model' reliably.</P> Thu, 17 Jun 2021 19:55:01 GMT https://community.databricks.com/t5/data-engineering/what-is-the-point-of-the-model-staging-and-promotion-functions/m-p/23574#M16296 sean_owen 2021-06-17T19:55:01Z
