I am running a MERGE query in Databricks on a Photon-enabled cluster, but I encountered the following error message:
== Photon Explanation ==
Commands are not directly photonized. They must be run to determine if they can be Photon-ized. If this message appears on an executed command, please check the next Job to ascertain if the resulting plan was Photon-ized.
The question is that I was expecting to say that the query is using photon. The displayed messages is not make it clear if it uses photon or not.
